When a technology becomes the “IT” product of the holiday season, there’s bound to be some misinformation out there. This year’s hot product is the consumer GPS – and it can truly do some amazing things, including: provide directions with real-time turn-by-turn navigation, help you avoid traffic and even make hands-free cell phone calls with Bluetooth. But there are also some things about GPS that just aren’t true. Here’s a look at some of the biggest myths about GPS technology.

5 Most Common Misconceptions about GPS:

Myth #1: The weather can affect your GPS

Fact: Cloudy or rainy conditions have nothing to do with the performance of your GPS device. Think about it like this: airplanes using GPS devices to navigate through cloudy conditions thousands of times a day. Last time we checked, the commercial aviation system was running without too many GPS-related problems. Well, the same technology they use is found in your car’s GPS devices. The only thing that can truly keep your GPS device from operating at peak performance are tall buildings, mountains and other large structures that may block it’s signal.

Myth #2: The government can track you because of your GPS device

Fact: It is true that some commercial grade GPS devices send out a signal about your whereabouts, the consumer GPS devices sold by Garmin, Magellan and other companies only receive information from satellite systems. While this news will be no doubt disconcerting to conspiracy theorists, the rest of us can breathe a little easier knowing that our whereabouts are private.

Myth #3: GPS devices mean you don’t have to watch the road

Fact: Just because you have a helpful GPS device in your car doesn’t mean you should be any less vigilant as a driver. It is important to watch the road and always pay attention to where you are in journey. In fact, some directions provided by your GPS device may take you through areas in which you don’t want to travel. It is always important to use these directions in conjunction with what you can see with your own eyes, and of course, common sense.

Myth #4: GPS devices don’t work outside of a local area

Fact: The beauty of GPS devices for your car is that they work almost anywhere. That means you can take your family for a cross-country drive and the GPS will provide with information every step of your journey. In fact, many GPS devices can help you find local points-of-interest along the way including parks, museums, restaurants and more.

Myth #5: GPS devices are too expensive

Fact: Of all the falsehoods out there about GPS devices, this one might be the most out of touch. Currently, there are more inexpensive GPS devices out there that at any time in the technology’s history. Even the high end models from Tom Tom, Garmin and others are reasonably priced, and the “basic” units (which are still packed with features) are affordable enough for almost any budget.

Before the arrival of the General Positioning System (GPS) technology, having a trip was certainly the most daunting experience in our life. For instance, it was perfectly acceptable to see a situation where someone was driving his car, another one was looking at the map to find the right direction, quite funny! Nowadays, this situation is obsolete and ridiculous for GPS systems have drastically changed the way we used to deal with route finding during a trip. Indeed by just installing a GPS device in your car, you can accurately and safely get the right direction.

Usually when someone mentions GPS, he is referring to the GPS receiver even if the GPS architecture is actually more complex than this small device installed in your car. In short, GPS systems are a cohort of 27 satellites rolling around the center of the Earth. Only 24 satellites are fully functional while the remaining ones are just used for storage purposes. The military industry pioneered the technology before being used for general purpose by the public.

Each GPS satellite powered by the Sun rotates around the center of the Earth completes a distance of about 12,000 miles which is equal to 19,300 kilometers. The actual trajectories of these satellites are made so that at least four satellites are available in the space at any time. The GPS receiver is responsible of finding these available satellites, working out its distance to these satellites and finding its position. This process makes use of a mathematical model called trilateration.

The GPS signals are hindered by weather conditions. Nowadays, there are many research projects aiming at finding ways around this issue in order to increase the correctness of GPS systems. Having located the satellites, the triliteration is used to work out its distance and reduce these errors.

Briefly speaking, GPS systems are used for several purposes mainly as guiding aid. The user simply needs to input his final destination and the GPS receiver will do the rest of the job. GPS systems can also be used for tracking purposed as it is noticed in the automobile industry.

The GPS technology is also used for many other purposes. For instance, in the automobile industry, GPS systems are used to deter car thieves. Private investigators are also making use of the GPS technology in order to monitor a cheating wife. The GPS technology is also extensively used in the military industry as it was pioneered by the army. Some military usages include navigation, target tracking, missile and weapon guidance, search and rescue lost soldiers and acknowledgement and map creation. The possibility to keep track of a vehicle position every time is an appealing feature of the GPS technology. Other systems can furthermore keep track of a driver. This feature is of great help to anxious parents who are concerned about their children’s ability to safely drive.

Another use of the GPS for civilian purpose is to help prevent civilian GPS guidance from being used in an enemy’s military or improvised weaponry, the US Government controls the export of civilian receivers. A US-based manufacturer cannot generally export a GPS receiver unless the receiver contains limits restricting it from functioning when it is simultaneously at an altitude above 18 kilometers and traveling at over 515 m/s.

The first thing to decide is how you plan on using a GPS and the second is how much you plan on spending on a GPS. Do you plan on using it in your car, for hiking and backpacking, or for hunting and/or fishing? Current GPS receivers are limited as to what they can do and are optimized a specific purpose. There are GPS specifically for flying, others for hunting and/or fishing, and others for Car Navigation. A few are just an electronic map that shows your position on the map screen. Others have no maps at all and can be just fine if you just want to know your longitude/latitude.

If you plan on using your GPS in an automobile, there are several choices: a basic or mapping handheld receiver; a dedicated automotive receiver; a GPS with a PDA; or a Laptop GPS.

Although handheld units can be used in a car there are several disadvantages-the screen can be hard to see due to its small size and some units will need to be placed forward on the dashboard where they can get a better signal. With a basic (non-mapping) unit you can tell where you are as long as you have a paper map with you to interpret that data.

A mapping unit is the more useful choice considering with driving usually involves roads. A dedicated automotive receiver is larger than a handheld in order to accommodate a screen large enough to be seen while driving. They are powered by the car’s electrical system and because of this; they can only be used in a vehicle. Automotive units usually have voice instructions to allow you to navigate without taking your eyes off the road. Prices start at about $500 US.

A GPS with a PDA needs clear access to the sky for satellite reception. Some receivers have the antenna built in or have the capability for an external antenna. An antenna on the seat of your car may or may not work. The console is the next best place – reception may be questionable. An air vent mount is better and a windshield mount or the antenna placed all the way forward on the dashboard is better yet. The most reliable place is for an external antenna to be attached to the roof of your car.

A laptop GPS requires a CF with an external antenna, a Bluetooth GPS receiver, a mouse-type GPS receiver, or be connected via a cable to a handheld GPS unit so the receiver can be placed in a position for good reception. Of course a laptop is large, but the main advantage is a very large screen for maps. If you have a need for a laptop in your car, this may be the best choice and a mouse-type receiver is inexpensive.

If you plan on using your GPS for hiking or backpacking there are three choices, a basic handheld receiver, a mapping handheld receiver and GPS with a PDA. It is also recommended that in addition to your GPS, you should take a paper map, and magnetic compass, and extra batteries. Weight and size need to be considered when deciding which GPS to choose. A basic receiver does not have mapping abilities, however it will display your location in a format that you choose, and most likely latitude/longitude. Providing your paper maps have your chosen position format marked on them, your GPS will allow you to find your location on the map. If your maps don’t have the position format grids marked already, this is something you’ll want to do yourself. These are going to be the least expensive choices for GPS, often less than $100 US and are as accurate as more expensive units; they just don’t have as many features. The main feature they lack is mapping capability.

For hunting or fishing many handheld models include best hunting and fishing times for a given location and date. Mapping handheld receivers are often larger, heavier, and/or have shorter battery lives than basic units. Shorter battery life means carrying more extra batteries adding bulk and weight. With a mapping handheld unit you will have the benefit of having the maps displayed on your GPS. These also include other benefits such as a barometric altimeter, an electronic compass, games, and a calendar and you can plan your route ahead of time on your PC and upload it to your GPS. These units display pre-loaded maps and map detail is reflected by the size and resolution of the screen. This means that mapping units are generally larger than basic units. The downside of a GPS with a PDA is that it will drain your battery quicker and it also of the top of your PDA. Mapping units are more expensive than basic units; prices start at about $150 US unless you get one with Bluetooth capabilities which are more expensive. For fishing a chart plotter/GPS or a GPS sounder are also available. The chart plotter/GPS and GPS sounders usually have a lot of features and start at about $400 US.

The Global positioning System (GPS) is a US military system primarily intended for global navigation. The system provides highly accurate positioning information for navigation. The GPS system consists of a constellation of 24 orbiting satellites. Each satellite has an on-board atomic clock, which is ideal for providing a highly accurate timing reference.

This article discusses how the GPS clock can be used to provide an accurate timing reference for computers and computer networks. The GPS system is often used for computer timing applications, such as NTP time servers and accurate timing references.

GPS Time

GPS time is continuously broadcast by the GPS system. Time is referenced to UTC (Universal Coordinated Time), which is the same worldwide and does not vary with time zones. GPS timing information can be received with relatively low-cost equipment, such as a GPS receiver and antenna.

The GPS signal is very weak low-power radio signal. The signal has two designated frequencies, L1 and L2. Frequency, L1, is the civilian GPS frequency transmitted at 1575.42 MHz. The signal travels in a straight line and can pass through clouds, glass and plastics but is blocked by objects such as metal and brickwork. The ideal location for a GPS antenna is therefore on rooftop with a good view of the sky. Often, antenna installation on the side of a building or in a window can provide a good enough view of the sky to give adequate results.

GPS Clock

The GPS system provides a free-to-air time synchronisation service; there are no on-going set-up or subscription charges. Many computer systems utilise the GPS clock as an accurate timing reference. Highly accurate NTP server systems use the GPS clock as an external reference to synchronise Network Time Protocol servers. Typically, a GPS receiver can provide timing information to within a few nanoseconds of UTC. The accuracy achieved with a GPS receiver is generally more than required for most computer network timing applications.

GPS Receiver Output

The GPS receiver constantly outputs position and timing information. Generally, information is transmitted to and from the receiver via a RS232 serial interface. Standard GPS interface protocols exist, the most common being NMEA. The NMEA protocol consists of a number of sentences, or character strings, transmitted at 4800 bits per second. Contained within each character string is accurate time and position information. Due to the latencies involved in serial communication, the NMEA sentences are not generally accurate enough to provide a timing reference. Therefore a pulse per second (PPS) output is utilised. A PPS output is an accurate pulse output each second that is aligned to the start of each second. The PPS output can be fed into a control line on the RS232 interface to provide a hardware interrupt input for accurate timing. Often the DCD RS232 line is utilised as a PPS input from the GPS receiver. The PPS output combined with NMEA timing and positioning information provides a highly accurate timing reference for computers.

GPS Antennas

The GPS antenna is a signal amplifier that boosts the GPS signal for transmission along a cable, usually coax, to the receiver. GPS antennas used for timing purposes are generally dome-shaped pole mounting devices for permanent installation in a static location. Typically, the GPS antenna is fairly small in size, measuring less than 900 mm in diameter

GPS Cabling

The cable distance that can be utilised by a GPS antenna and receiver depends on the amplification of the GPS antenna and the quality of coax used in the installation. A typical GPS antenna may have a gain of 35 db. Low-quality coax such as RG58 has an attenuation of 0.64 db/m at 1575 MHz. Therefore, a cable run of 55m can be obtained using RG58 cable. Higher quality coax, such as LMR400, an unaided cable run of 200m can be achieved. However, very high quality coax can be expensive. A good compromise is LMR200 cable, which can be run unaided to 80m. Longer distances can be achieved with the aid of GPS amplifiers, which amplify the GPS signal still further, to increase cable distance.

Global Positioning Systems (GPS) have been changing the way the world works since its inception as a tool for soldiers during World War Two. Although the design may have been different, the idea of GPS has been around for over half a century.

The design of the GPS is based on similar radio navigation systems, called the Decca Navigator, and were first used in the 1940’s. When the Soviet Union launched the world’s first satellite “Sputnik” in 1957, U.S. scientists discovered that radio transmissions sent from the satellite could be used to pinpoint where the satellite was in relation to the earth. Thus, the idea of the birth of the modern-day version of the GPS was created.

The very first satellite navigation system, which was used by the United States Navy, was tested in 1960. As the technology developed, so too did advancements in locating your position in the world. In the 1970’s, the Omega Navigation System became the first world-wide radio navigation system. It was not until 1978 that an experimental Block-I GPS satellite was launched into space, ushering in a new era for civilian use of GPS. The amount of satellites using GPS’ have increased over the past 30 years, and as a result, many people have benefited from the use of navigation tools used by the GPS.

The civilian benefits of using a GPS are almost unlimited. The ability to determine the receiver’s location allows GPS receivers to perform as a tool for surveying and also as a tool for navigation. The GPS has the ability to determine relative movement, and as a result, can calculate local velocity and orientation. These benefits are most commonly used in vessels or photographs of the earth. Time transfer is also a GPS skill which allows clocks to become synchronized to exact standards. GPS has revolutionized the synchronization of the planet – there aren’t very many tools out there that can say the same thing!

Finally, by using the GPS measurements of the planet, scientists are able to better understand the Earth’s environment, such as the atmosphere and planet’s gravity. By observing how those environmental components alter the prorogation of GPS signals, scientists can find out new information on the progression of the planet.

Since those early days in 1993, the GPS system has come a long way. In 1994, a complete constellation of 24 satellites was in orbit around the Earth.

By 1996, U.S. President Bill Clinton, issued a statement that declared the creation of an Interagency GPS executive board – as a result, GPS systems became more advanced and enhanced user accuracy and reliability, particularly with aviation. The most recent launch of a GPS satellite was in November of 2006, with the oldest satellite still in orbit since 1991, still circling the globe.

GPS systems have come a long way since the idea came to fruition in the Second World War. GPS has allowed the common person the ability to navigate, with exact precision, around the globe. When you know where you are in the world, you can go anywhere! These units are very important to personal safety as they can be used to track vehicles and other valuable items. Here are some ways that citizens are using GPS:

(1) In their cars so they know where their teenage drivers are and that they are safe.

(2) To help retrieve stolen vehicles faster.

(3) To track shipments and other traveling goods.

(4) To prevent kidnappings with GPS teddy bears and backpacks.

(5) GPS units are extremely helpful to both civilians and military personnel alike. However, to help prevent civilian GPS guidance from being used as improvised weaponry, the United States government controls the export of civilian GPS receivers. For this reason it is very important that you purchase your GPS system from a reputable merchant.

Whether you are interested in GPS, or simply are interested in gathering information for a future purchase, it is important to find reputable merchants. Your first step when looking for an effective self-defence should be at http://bljsselfdefense.com/index.php . This company offers a large variety of merchandise, including GPS systems, and provides education on the necessary information needed to protect yourself and your family.

Effective GPS tracking devices are great tools to help you keep track of your loved ones, employees, products and equipment. Since these GPS tracking devices are so prevalent today, you will be able to find a suitable solution that fits your budget. Installing a GPS tracking device is a good financial and management decision. It is difficult to imagine running a business today without a GPS tracking device. Just imagine the manual communication and tracking overheads that will be required to track where your company’s assets are and whether your customers are being serviced effectively. You will need to make frequent phone calls to keep track of everyone and to ensure that the entire business process flow is working well.

With the amazing advances in technology, GPS tracking devices have made things like tracking of employees and vehicles much easier. There are sufficient proven advantages in installing a GPS tracking device. Some of these are:

1) Monitor and plan the movement of your company’s vehicles

With a GPS tracking device, you can easily plan an efficient delivery route without much time or money being wasted. In the past, before the introduction of GPS tracking devices, it would be almost impossible for you to realize if some of your employees have been skiving on their job with the company’s vehicles in tow.

However, things are different now with GPS tracking devices being installed by more companies. You will be able to figure out the real-time location of your driver and if the travelling time to the planned destination took as long or longer.

2) Recover stolen goods

It is nearly impossible to predict when a company vehicle will be stolen. So installing a GPS tracking device ahead of time is smart. Without a GPS tracking device, it will take the police a longer time to track down the stolen vehicle. In that critical lost time, both the vehicle and its precious content may be disposed off.

With a GPS tracking device installed, it will be of great help to the police as the time taken to find the vehicle will be greatly reduced.

3) Ensure the safety of your employees

GPS tracking devices can improve the safety of your employees. Employees are exposed to the danger of piracy or highway robbery if crooks realize that they are delivering goods that are of high value. Since GPS tracking devices can help keep track of your employees in real-time, you can offer help quickly and minimize their risks if should they meet with any danger.

A Portable GPS Helps You Get Around

Having a portable GPS tracking system with you when you are out on your trip is always advantageous. A portable GPS tracking system can help you find your way around in various circumstances. It can help you if you are on a jungle trek. It can also help you if you are trying to make your way around busy city centers.

In the old days if you were preparing for a trek, you would need to find an appropriate map that covers the region where you plan to explore. You run the risk of venturing off into areas that are not covered by the paper map. It is unlikely that you will bring enough maps to cover all possible contingencies. Your planned route may be blocked by fallen trees or landslides. The area may have been flooded or waterlogged. The detours that you may have to take may heighten the chances of you getting lost. Your map may also be damaged by heavy rain if the map is not well protected in a waterproof sheath. If it gets dark and you are unprepared, you may not be able to read your map. Getting lost in the woods or the jungle can be a harrowing experience. If you need a search and rescue mission to get you out of the situation, this may take time. A rugged portable GPS device may be a real lifesaver in these situations.

The portable GPS device can easily indicate to the user their position with just a click of a button. From that position, the user can try to find a way out of the area and the chances of getting lost are greatly minimized. You do not need lots of space in your luggage to accommodate a portable GPS.

It is generally quite easy to use a portable GPS as you can get instructions that appear on the screen’s display. Moreover, most models now come with a voice sampler that provides you instructions clearly instead of reading them off the screen. This allows the user to understand the portable GPS device in a more interactive way.

Basically, a portable GPS is a fantastic way for determining your location with the help of the voice sampler and allows the user to find their way through unfamiliar places with ease. In many cases, the use of a portable GPS system helps to avert the user from getting into difficult or dangerous situations.

Read Reviews of the Best GPS Systems Available

It is more than difficult to find a good GPS review on the Internet. The reason is this: GPS devices all do the same thing. They show your location on an electronic map, and then show you how to get where you’re going. Now, by GPS device I mean a car GPS device that you buy separately from your automobile and either hang from a bracket on your windshield or put next to you on the seat.

So, the key to a good GPS review is understanding the features that various GPS devices offer at each price point.

What do all GPS devices have in common?

All car GPS devices that are on the market today have a touch screen where you can enter information into the unit, such as your destination address. All auto-calculate the route to that address, and all give you spoken directions of some sort as you drive to your destination. In addition to this, virtually all GPS devices come pre-loaded with maps, usually at least of the continental United States, have an internal battery for emergency use, and can toggle between 2D and 3D map views. (3D gives you a slightly more realistic view of what you should be seeing in front of you.)

There are exceptions to all of these rules, but almost all are in the older models.

Who are the industry leaders?

There are three main manufacturers of car GPS systems, Garmin, Magellan, and Tom Tom.

Garmin sells about one out of two of all the car GPS systems sold in the world. They are known for making a quality product. Magellan was an early leader in GPS systems that can route you to more than one destination. They do not have nearly the market share that Garmin has. Tom Tom is a late arrival who is quickly catching up. According to Tom Tom, their GPS system, the Tom Tom One, is the best selling system in the world.

What are the main features to look for in a GPS system?

In this GPS review, let’s start at the cheap end and work our way up.

You can buy a GPS system for less than $200. The Garmin nuvi 200 and the Tom Tom One, 3rd Edition currently sell for less than $200 at Amazon.

As you increase price, the main features you can add are

Voice prompts that actually say the street name

Cheaper GPS devices only tell you where to turn. They say something like, “Turn right, here.” A good feature to be aware of is having the GPS device actually say the street name of the road you need to turn on. So, instead of “Turn right, here,” a better GPS system would say, “Turn right on Highland Avenue,” or “Take a left onto the entrance to I-95.” Devices with spoken street names usually start around $300.

Another feature to look out for is real-time traffic and weather capability

Wouldn’t it be nice if your GPS device could not only tell you how to drive from Atlanta, Georgia to Charlotte, North Carolina, but could alert you to bad traffic conditions in time to take a detour? Well, many of the more expensive units can. How does your GPS device know what the traffic is like up ahead? GPS devices that have this capability are tuned to either an FM or satellite radio frequency that broadcasts this information. If your device has this function, then it will usually come with a free trial subscription to this service. After that, it’s going to cost you, but the cost is fairly low, especially considering how useful real-time traffic is. Along with real-time traffic usually comes real-time weather — an added bonus.

Any of the Garmin nuvis from the nuvi 350 up have FM traffic capability. The nuvi 350 runs slightly less than $300 at Amazon. If you want a Magellan that route you around hold ups, you’ll be paying $300 to $350. All of the Tom Tom’s have this capability, even the Tom Tom One, 3rd Edition, which is one of the cheapest units on the market, currently running around $200.

Do you regularly use your cell phone while driving?

I know I do. It’s problematic to hold the cell phone in one hand and negotiate your way through heavy traffic on a busy interchange. If your phone supports Bluetooth technology you can get a GPS receiver with that same capability and actually use it to make and receive calls. You answer an incoming call by just tapping on the touch screen. You make an outgoing call by either entering the number in your GPS’s touch screen key pad or by accessing numbers stored in the device — downloaded from your phone when you first set up your receiver. So, now instead of wearing that silly Bluetooth headset and looking like a member of the Borg Collective, you can just have your GPS device do double duty. If you make a lot of calls while driving, this is definitely a feature you need to think about.

As to what Bluetooth is going to run you, the Garmin nuvi 360 is their lowest priced Bluetooth model. It currently sells for slightly more than $300. Virtually all of their upper end products have Bluetooth. Two of the Magellan Maestro series, the 3250 and the widescreen version, the 4250 have Bluetooth. They run around $280 and $350 respectively. The Tom Tom GO series has Bluetooth. They run anywhere from $350 to $900.

Multi-destination routing

It’s not something that I use much, but it’s definitely worth knowing about. Multi-destination routing means you can enter multiple routes into your GPS at one time and it will calculate the best route that includes all of your destinations.

Garmin’s nuvi 700 series does this, as well as a couple of their StreetPilot series. Most of the Magellan Maestro series does this – they can be programmed to hold up to 20 separate destinations. As for Tom Tom, the GO 510 can hold up to 15 routes. As to price, the nuvi 700s run anywhere from mid-$400s to almost $700. The Magellans are slightly less expensive, running from mid-$200s to the mid-$300s. The GO 510 costs slightly less than $500 at Amazon right now. The voice prompts, Bluetooth, and multi-destination routing are three of the more important features to consider.

Also, you want to keep in mind what maps your device comes with. And, almost as important, how many preprogrammed Points of Interest are included in its database.

Points of Interest

(POIs) are names, addresses, and phone numbers of possible destinations, anything from the nearest Starbucks to Yellowstone National Park. The lower priced units come with less than 1 million POIs. That’s not enough, if you’re going to be using this feature. For use outside of your normal travel routes, you really want a few million POIs. Virtually all GPS devices now come with this, except the lowest prices models, like the Garmin nuvi 200, which only has regional maps and less than 1 million POIs. (There’s nothing wrong with fewer POIs, if you’re not planning on needing them, but they sure can come in handy.)

Yet another feature to keep in mind is screen size. The standard size is 3.5 inches. This is measured on a diagonal. So the screen for the nuvi 270, for instance, measures 2.8″ by 2.1″. The so called widescreens measure 4.3 inches on the diagonal. You’re actually getting 70% more screen this way.

Why is screen size important?

It has to do with ease and safety of use while driving. Personally, I like a wide screen, but then again, my car is fairly big and has a big windshield. The difference in price between a regular screen and a widescreen is about $80. That might be money well spent. On the other hand, if you drive a smaller vehicle with less windshield area, the wider screen might be more of a hazard than a safety feature.

Currently at Amazon, Garmin nuvis (their newer product line) run from $179 for the nuvi 200 to $699 for the nuvi 770. The Magellan Maestros are running from $168 for the 3100 to $356 for the widescreen 4250. Tom Tom’s GPS systems are currently priced from slightly less than $200 for the Tom Tom One, 3rd Edition, to $899 for the GO 700 (which is overpriced).

Whatever you do, don’t procrastinate. Even with a good GPS review, with all of these confusing choices it’s tempting to just wait for whatever the next model is going to be. What you’re missing by doing that is lots less stress while driving! Imagine, if you’re a guy being able to always (really) know where you’re going despite what your wife or girlfriend says. And, even better, if you’re a woman you won’t have to pester your husband or boyfriend to stop at the local gas station and admit that they’re lost – not an easy admission for a guy. (I should know!)

Marine GPS based devices are a boon to all seafarers. It is based on the Global Positioning System or GPS. It is a constellation of satellites which orbit the earth twice a day, transmitting exact time and position information. With GPS, you can spot your precise location and get back to your original destination. A marine GPS can be of a great help should you get lost in any large body of water – lakes, seas or oceans.

A marine GPS device’s use starts off the first step prior to going out to sea – voyage planning. One of the most vital advantages of using marine GPS is that it is a device commonly responsible for saving lives. In addition, marine GPS also reduces the chances of getting lost at sea.

Normally, marine GPS systems are used by the Coast Guard to keep track of ships as they move along the coastlines. This will give them an idea of the direction in which a vessel is heading. They may be able to communicate with the vessel and provide precise information regarding its current position and directions to take to get to its destination.

With marine GPS technology, planning routes for other ships have been made possible for the crew. In addition, this technology also helps in avoiding collisions that may cause fatality or other accidents that may cause damage to the ship.

Basically, there are many different kinds of marine GPS in the market. They range from voice-enabled computer systems to simple radar-oriented GPS systems. The more popular marine GPS systems will be the one that is voice-enabled. Somehow seafarers relate to this type of marine GPS systems since they find some comfort in listening to a ‘human’ voice; though it may be a computer generated one. As for the radar-oriented GPS systems, they only give off a beep as a form of signal. This makes the interaction with the marine GPS a less ‘personal’ one; although they are very effective in locating positions.

People usually perceive that they need lots of sea knowledge in order to operate a marine GPS. However this is not the case. Just like any other GPS system, all you need to do is to read the manual and understand the signals that are shown on the GPS device. Thereafter, you can program the marine GPS device according to the requirements of your journey on the high seas. Whether you use a marine GPS on land or at sea, they provide user friendly interfaces that makes them easy for everyone to operate.
