GPS Applications for the Common Man
Well, think of GPS as an electronic gadget just like your radio. Once you knew how to use your radio, you never had to know how the radio works. The same can be said about GPS receivers – almost. Almost so because radios are cheap, but not GPS receivers. You can buy radios for ten bucks, whereas GPS receivers can cost you several thousand dollars. Expensive items always attract the ‘smart’ marketers. When you are buying GPS it can be useful to know some basics of how GPS works, just enough to get a good deal at the store.
For starters let us try to understand what can you use a GPS receiver for. Similar to your radio that can play audio from radio stations, there are several fundamental capabilities of a GPS receiver. Depending on the application, a set of GPS receiver capabilities are used. The GPS receiver is capable of calculating the following:
(1) GPS user’s location in terms of X, Y, Z co-ordinates
(2) Present time and date
(3) GPS user’s velocity, acceleration,..
That’s pretty much it. Examples:
Car navigation: A GPS receiver used for car navigation would employ capability (1) of a GPS receiver. A map database stored in digital format used in conjunction with capability 1 provides the requisite navigational capabilities.
Trucking management: If you are running a business where you deliver the goods using ground transportation such as trucks – lots of them. How you do you plan the route for all the trucks such that, you minimize fuel cost, minimize the time spent for offloading the goods that you are delivering and also reduce travel time. Well now, if you had a GPS receiver in each of the trucks, you would be able to record the delivery location and time for offloading. The next time, when you want to deliver a similar item, you know which truck to load it on based on past experience.
Depending on the application, GPS receivers in the market sell in a very broad price range. You can buy one for less than hundred dollars and one with all the bells and whistles for more than a grand. The right thing for you to do is to compare a comprehensive list of GPS receivers in the market and check against your application and budget. Websites like www.gadgetknowledge.com/gps1.html can get you started in the GPS arena. What you want to look for is a listing of GPS receivers in the market, a basic understanding of the various features/capabilities that you can expect out of your GPS receiver, a list of accessories that may be useful for your application and a tutorial introduction to what GPS is all about so that you make good use of your GPS receiver.

Some GPS Tracking Devices To Choose From When Considering GPS For Children
One of the most out in the open devices there is are GPS locator watches. Two of these types of GPS devices are Chitter Chatter and Wherify. Chitter Chatter one of the smallest GPS devices in the world. It resembles a wrist watch and is generally regarded to be accurate to within 300 feet. The Wherify GPS Locator Watch is, as its name suggests, a watch. However this GPS watch is resistant to water and resistant to cuts. The watch can contact emergency authorities as well as the parents if two outer buttons on the watch are held down. A very nice additional feature of this particular GPS device is that it prevents someone from removing it when its owner does not wish it. With these such devices, all a parent need to do is to log into the monitoring website and with as few mouse clicks, they can find their child.
Not to be outdone, some wireless service providers are also offering their own take on GPS tracking systems. Verizon has a monitoring service utilizing the GPS locator embedded in a cell phone. The Verizon service is called Chaperone. Sprint also has a service which is called Family Locator. One of the biggest differences between Chaperone and Family Locator is that while the Chaperone service may only be used with Verizon supplied cell phones, Family Locator can be used with any web capable phone.
Whether it is a GPS wrist watch or a GPS cell phone, these are some of more dual-use GPS tracking devices that parents can use to provide GPS for children. There are many others to choose from so parents should do as much research as they can before settling on the right GPS tracking system for their family.

GPS Technology and Mobile Phones
The U.S. FCC (Federal Communications Commission) has mandated the E911 (Enhanced 911) which requires that the location of any cell phone used to call 9-1-1 can be determined. This program is divided into two parts; the first requires carriers to report the telephone number of the caller and the location of the antenna that received the call. The second part requires carriers to be able to provide a more precise location. This will require that the manufacturers to install a GPS receiver in all cell phones. The benefit of this not only means that a cell phone can be quickly located, but that cell phones will have the ability to receive driving directions, and to be used as a hand-held GPS out of the car.
There are two ways that a GPS cell phone can be used to get driving directions. The first is to subscribe to a GPS navigation service, which is becoming available but is limited at this time. The second way is through use of a software program. Being able to subscribe to a navigation service has its disadvantages, if you are outside your coverage area your navigation functions won’t work. Plus, not only do you have to purchase a GPS cell phone, you must also pay a set up fee and a monthly fee and be under a 3 month to one year contract.
The second way to get driving directions is to buy a software program, but you need to have a compatible cell phone. The programs and maps are on a memory card and there is no need to pay a monthly fee and since the maps are in the phone you are not dependent on a GPRS connection.
If you want to take your GPS cell phone with you while out of your car, not only are there integrated GPS cell phones, there are GPS add-ons available also.
Another advantage to having a cell phone with GPS technology is that parents know where their children are at any time (as long as they have the phone with them). Some carriers are offering this child location service as a ‘peace of mind’ feature. There is usually a monthly service charge for this service.

GPS Navigation System – Amazing Innovation In Your Car
However, using a GPS navigation system inside an ordinary automobile, is somewhat different than using it on airplane. Transportation by car is dependent on the roads that are traveled. In reality, GPS readings alone such as longitude, latitude and altitude are for all practical purposes useless when you’re driving to Aunt Mabel’s house. When driving an automobile you can end up going through urban canyons and tunnels, where satellite singles cannot get through. So a different type of GPS technology is needed for automobile GPS navigation systems.
There has been potential for years in automobile GPS navigation systems, and industry has tried various ways to implement them. In 1983, Honda introduced an automobile navigation system that was based primarily on an accelerometer, not on GPS. It wasn’t until 1990 that an automobile GPS system was released to the public consumer by Pioneer. Automobile GPS Navigation systems had yet to really come into use until Magellan released its version in the US in 1995. Since then more portable GPS systems have been developed for greater ease of use for people.
Automobile GPS Navigation System Components
An automobile GPS Navigation System requires a GPS receiver and a map database. Some systems also have drive train sensors to supplement when GPS signals are blocked for brief periods.
The database map converts the GPS portable systems coordinates into map locations, such as street names and addresses. Some map databases contain GPS coordinates for specific locations, such as points of interest or rest stops. It’s the information in the database, however, that directs you to your location, either visually or by voice. Which means your GPS navigation system is only as good as your GPS car systems map database.
Commercial Applications
Many corporations and businesses use GPS navigation system within their vehicles to dispatch and track vehicles. In various cities throughout the US, taxis come equipped with a GPS navigation system. Dispatchers at the taxi company know where all the taxis are located at any given point in time, and can dispatch them more effectively than before.
Commercial shipping companies find GPS navigation systems indispensable. In addition to being able to track where the trucks are whenever they want, they can also give the customer a tracking number, and then the customer would have the ability to track their individual package themselves.

Understanding the Different Applications of the GPS Coordinate
You are probably thinking that the reason you want a gps is to know where you are. You never thought that you would have to know various coordinates in order to find your location. Before you start worrying and panicking you should take a look at your manual that came with your gps system.
In this manual you will be informed about the fact that the system you are holding uses signals from satellites to state your location. You will also be informed of the type of gps coordinate system that is used by your unit. Following these simple directions you can use the program to find your location using the coordinates that you receive from the gps satellites.
To make this dilemma you face fade away even more we should see how you will be receiving this gps coordinate information. The first step is to understand that your gps receiver will send signals to a number of gps satellites. As the signals travel at a set pace the gps unit will have the ability of calculating the position and the distance of the satellites to the receiver’s position.
The receiver will also use the signals from about two other gps satellites to get accurate information. From this information the gps unit can then ascertain the user’s position in relation to the information from the satellite.
The gps coordinate receiver has two different applications. There is the original military usage receiver and the civilian gps receiver.
Of these two devices the military based gps system is more accurate in displaying the gps coordinate information. This has not however stopped civilian manufactures from trying to develop their gps units to receive coordinate information much more accurately. This updating of the gps coordinate information becomes even more accurate with each new generation of gps systems and receivers.
While this information may seem to be confusing there is only one fact that you need to keep in mind. This is the reason why the gps receiver is in your possession. With the calculations from the gps satellites the gps coordinate receiver will be able to pin point the position you are in and the distance to the place that you want be at. This is the only reason for you to have a gps handheld unit in your possession.

GPS Tracking System – How Its Components Work
complex system, the GPS tracking system. It is made up of three
componentsL satellites that orbit the earth, control and monitoring
stations and the GPS receivers. It is a radionavigation system
providing reliable positioning, navigating, and timing services not
just for the military but also to civilian users as well in any part
of the world. The GPS tracking system has drastically changed the
world of navigation through land, sea and air, in all weather, 24/7.
The Global Positioning System (GPS) is a U.S. space-based
radionavigation system that provides reliable positioning, navigation,
and timing services to civilian users on a continuous worldwide basis
– freely available to all. For anyone with a GPS receiver, the system
will provide location and time. GPS provides accurate location and
time information for an unlimited number of people in all weather, day
and night, anywhere in the world.
In the 1960s the U.S. Navy and Air Force worked together on a number
of systems that would be able to provide a variety of navigation
applications. In 1973 the Department of Defense aimed to direct the
services in unifying their systems. The concept of the tracking
system would be atomic clocks onboard satellites was tested
successfully by an earlier Navy program called TIMATION. The Air
Force would operate the new system called the Navstar Global
Positioning System. From then on, it has since been known as simply
GPS or Global Positioning System.
The GPS tracking System Satellites
Today’s GPS Operational Constellation is funded and controlled by the
U.S. Department of Defense and being operated by the U.S. Military.
It is comprised of three major components: a “constellation” of
satellites in Earth orbit, ground stations that controlled the system
and receivers hand carried by the users. It was so designed so that
these receivers could be made small and inexpensive and would not
require atomic clocks.
The GPS tracking system is an aerospace technology comprising of at
least 24 operational satellites at all times. Each satellite is on a
circular orbit 20,000 kilometers above the Earth on a 12-hour period.
In order to make sure that these satellites are detected from anywhere
on the surface of the Earth, the satellites are divided into six
groups having four space vehicles each. The six orbital planes
completely surround the Earth, equally spaced 60 degrees apart and at
an angle of about 50 degrees with respect to the equatorial plane.
Each group is assigned a different path to follow. The orbit altitude
is such, that the GPS satellites recapitulate the same ground track
and configuration at approximately over any point each in 24 hours.
The GPS tracking system’s navigation message consists of time-tagged
data bits that mark the time of transmission of each subframe at the
time they are being transmitted by the space vehicle. A data bit
frame consists of 1500 bits divided into five 300-bit subframes and a
data frame is being transmitted at an interval of 30 seconds. There
are three six-second subframes containing orbital and clock data.
Precise clock corrections are sent in subframe one and orbital data
sets or ephemeris data parameters for the transmitting space vehicle
are sent in subframes two and three. Various pages of the system data
are being transmitted in subframes four and five. So the GPS tracking
system has an entire set of twenty-five frames or 125 subframes
creating the complete navigation message sent over a 12.5-minute
period.
The GPS Tracking System Equipment on the Ground
Ground stations are used so that each satellite orbit are accurately
tracked. The GPS tracking system has ground stations which is
comprised of a receiver and antenna, as well as communication tools to
transmit the data to the data center. When the GPS satellites supply
specially coded signals, the omni-directional antenna at each site
picks up the signals and that is processed in a receiver. The
receiver then separates the signals in various channels for a
particular satellite and frequency at a particular time. Once the
signals are isolated, the receiver now decodes them and splits them
into individual frequencies to calculate position, velocity, direction
and time anywhere on Earth.
At least four GPS satellite signals consisting of space segments are
used in computing positions in three-dimensional locations – latitude,
longitude and altitude – and the time offset in the receiver clock.
All GPS tracking system satellites have synchronized operations so
that the signals are transmitted at the speed of light to the
equipment on the ground. Each GPS satellite broadcasts data
indicating its location and current time.
Since the GPS tracking system sites are constructed throughout the
world and are being monitored by different institutions worldwide,
there are many different data center locations. The role of the data
center is to both monitor and control the GPS tracking system
stations. The data center uses an automated computer system in
retrieving and analyzing data from the receivers. Once processed, the
data, including the original raw data, are sent to scientists around
the glob for use in various applications.
From laboriously built landmarks by our ancestors to shooting the
stars to chronometers to satellites, our technology has evolved faster
than we could ever imagine. The GPS tracking system is the most
recent and significant advancement in navigation and positioning
technology. This new constellation of artificial stars serves this
important need for both the military and civilian users and is now
fast becoming important in everyday life.
