GPS Systems for Ntp Time Servers and Timing Applications

Nowadays GPS is most commonly known for vehicle navigation solutions. However, the GPS system can be used for many other useful purposes. For instance, many computer network time synchronisation solutions, such as NTP time servers, use the atomic clocks on board each GPS satellite for accurate timing. The GPS system can be used as an accurate reference clock for synchronising time-critical applications on computers and networks. This article describes how computer systems can utilise GPS time and discusses what equipment is required to provide a precision timing reference.

The GPS system is a United States military system intended for global navigation. The GPS system is a space-based system, consisting of a network of 24 orbiting satellites. Precise navigation and positioning is achieved by utilising precision timing signals and triangulation between multiple satellites. Each orbiting satellite has an integrated atomic clock timing reference to provide ultra high precision timing. Each satellite broadcasts timing information to within a few nanoseconds of the correct time to provide positioning to an accuracy of better than 10m. This precise timing information can be used by NTP time servers and other computer timing equipment as a highly accurate time reference. The great thing about GPS is that it works anywhere in the world and is entirely free to air service.

Each GPS satellite transmits a low-power radio signal down to the surface of the Earth. Two separate frequencies are utilised, designated L1 and L2. The L1 band is the civilian signal; transmitted at 1575.42 MHz. L2 is the military frequency, intended for ultra-high precision positioning. The radio signals are transmitted from the satellites by line of sight. The transmitted signal is easily powerful enough to pass through clouds, glass and most plastics but is absorbed by more substantial material such as brick, roofing materials and metals. The ideal location for a GPS antenna tends to be outdoors and ideally on a rooftop with the best possible view of the sky.

With the advent of GPS navigation equipment for the mass market, GPS antennas and receivers can be obtained at very reasonable cost. A GPS antenna is utilised to receive and amplify the GPS radio signals. While a GPS receiver decodes the information and presents it in a computer readable format. Many antennas are available with integrated receivers but these have the drawback of only providing a few meters of cabling to the host NTP time server or computer system. Marine antennas are designed to withstand the worst of the weather, they typically ***** onto a threaded pole to provide a secure mounting system. These antennas provide the best solution for static timing applications.

The GPS receiver is generally embedded into the NTP time server or encapsulated within an enclosure. A GPS receiver is a small elecronic device that receives amplified GPS signals from an antenna via a coaxial cable. The receiver decodes these signal and provides a computer readable output usually via a RS232 or USB interface. Most receivers provide decoded information such as: position, visible satellites, precise time and an accurate pulse output timing reference.

Coaxial cable is utilised to provide a connection between the GPS antenna and receiver. The cable distance can be critical. The antenna must amplify the GPS signal sufficiently to overcome any cable losses associated with the cable run utilised. Better quality antennas generally provide more amplification (gain) additionally higher quality coax cables can be used with much smaller signal losses per meter allowing for relatively long cable runs between a antenna and receiver. In order to extend cable runs still further GPS amplifiers can be used to boost the signal transmitted down the coax cable. Typically, a GPS amplifier sits in-line on the coax cable and is powered from the receiver. Multiple amplifiers can be used for extremely long cable runs.

A roof mounted GPS antenna can be prone to lightning strikes and voltage surges. It is recommended that surge suppressors are utilised to protect expensive NTP time server and timing systems from potential damage. A surge suppressor is essentially a barrier that sits in-line on the coax cable between the antenna and receiver that protects the receiver from any potential damage due to voltage surges.

To summarise, the GPS system provides a highly precise timing reference for NTP time servers and other computer timing equipment. It is a reliable free to air service that can be used anywhere in the world. Additionally, with the boom in vehicle navigation systems the technology required to receive GPS broadcasts is continually falling in price.

3 Essentials for a Fabulous Trip: Gps, Money, and a Spirit of Adventure

Traveling is a great way to escape from the daily grind. In fact, a change of scenery has proved to be an effective stress killer. If you are gearing up for a fabulous trip, don’t forget to take along the three essentials: a GPS, a wallet full of money, and a spirit of adventure!

Now, if you are thinking to yourself is a GPS really a travel essential, the answer is most definitely yes! A Global Positioning System (GPS) or a GPS technology can help you locate specific destinations and even provide directions when you find yourself going around in circles (which, let’s face it, happens all the time to people when they drive around a city they have never been to before).

So how exactly does a GPS work? Well, a GPS transmits precise microwave signals from a satellite to the GPS receiver, which then allows it to determine its current location, time, and velocity. GPS enabled devices can be used in the car or on foot. When installed in vehicles, GPS devices help drivers find their way through city streets. Campers and hikers can also use them to navigate through unfamiliar terrain. A GPS technology not only works as a pathfinder, but it can also play a vital role in planning your itinerary. You can quickly and easily find restaurants, hotels, gas stations, and more that are all within a short distance of your vacation destination.

Many of the latest and best GPS gadgets and GPS accessories are available online at Tupelo Super Store. The NavStick USB GPS for Laptop is a unique GPS dongle that can easily transform your laptop into a personal navigator by simply plugging it into the USB port of your computer. These GPS dongles are pocket-sized and lightweight gizmos that fit nicely into your laptop bag. The Garmin GPS 72 is another useful product that provides accurate GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS). These units are waterproof, durable, unsinkable, and high-performing. Incorporating 500 user waypoints with names and graphic symbols, including 50 reversible routes, the Garmin GPS 72 provides land and marine navigation. The Bluetooth Keychain GPS w/Live is a sleek and a compact Bluetooth GPS receiver. This keychain Bluetooth GPS lets you search for maps and directions using Live Search for Windows on Bluetooth-enabled cell phones, PDAs, and laptops. The USG All-in-One Car Navigator is your typical car model. It has pre-loaded maps of the United States, Canada, Puerto Rico, and the U.S. Virgin Islands. This navigation system displays maps in both 2D and 3D and offers precise and accurate routing.

NTP GPS Server – Using Satellite Time Signals

The NTP GPS server is a dedicated device that uses the time signal from the GPS (Global Positioning System) network. GPS is now a common tool for motorists with satellite navigation devices fitted to most new cars. But GPS is far more than just an aid for positioning, at the very heart of the GPS network is the atomic clocks that are inside each GPS satellite.

The GPS system works by transmitting the time from these clocks along with the position and velocity of the satellite. A satellite navigation receiver will work out when it receives this time how long it took to arrive and therefore how far the signal travelled. Using three or more of these signals the satellite navigation device can work out exactly where it is.

GPS can only do this because of the atomic clocks that it uses to transmit the time signals. These time signals travel, like all radio signals, at the speed of light so an inaccuracy of just 1 millisecond (1/1000 of a second) could result in the satellite navigation being nearly 300 kilometres out.

Because these clocks have to be so accurate, they make an ideal source of time for a NTP time server. NTP (Network Time Protocol) is the software that distributes the time from the time server to the network. GPS time and UTC (Coordinated Universal Time) the civil timescale is not quite the same thing but are base don the same timescale so NTP has no trouble converting it. Using a dedicated NTP GPS server a network can be realistically synchronised to within a few milliseconds of UTC

The GPS clock is another term often given to a GPS time server. The GPS network consists of 21 active satellites (and a few spare) 10,000 miles in orbit above the Earth and each satellite circles the Earth twice a day. Designed for satellite navigation, A GPS receiver needs at least three satellites to maintain a position. However, in the case of a GPS clock just one satellite is required making it far easier to obtain a reliable signal.

Each satellite continuously transmits its own position and a time code. The time code is generated by an onboard atomic clock and is highly accurate, it has to be as this information is used by the GPS receiver to triangulate a position and if it was just half a second out the Sat Nav. unit would be inaccurate by thousands of miles.

How Do I Find the GPS Coordinates of a Location – Definition and Application of the GPS Map Coordinate

There are many coordinate systems available in mathematics. These aim at locating without ambiguity a given in regard to the origins of the coordinate system. Many coordinate systems are used in mathematics and physics. For instance, the Cartesian coordinate system and the polar coordinate system are used in science. The General Positioning System (GPS) makes use of coordinate systems based on the latitude and longitude tenets. The longitude of an object in the space is its angular distance (east or west) from a reference meridian, the Greenwich one for instance while the latitude is the angular distance (north or south) from the equator. In order to track an object in the space, we usually need its latitude as well as its longitude. For instance, as soon as a GPS device sends signals to a satellite positioned in the space, the satellite will work your exact coordinates before sending another signal to the receiver of your GPS device. Using this process, the GPS system can determine your exact position, heading and speed.

At the beginning, many GPS systems used to ask to the user to manually input his map coordinate. However, for people not knowing anything about mathematics or even about the suitable coordinate system to be used, they were quickly annoyed. In order to address this setback, GPS system vendors have founded a new way to automatically compute a map coordinate. This way, your GPS device will be assigned the right and suitable map coordinate for your given destination in order to work out your accurate location, speed and heading. However, users may still manually type the map coordinates if they fancy, but they should bear in mind that the device was designed to perform that difficult task. This accounts for its usefulness especially for traveling purposes. Being aware of all this information beforehand is a huge boon for your trip.

Exceptional mathematicians are still allowed to enter their customized GPS map coordinates. However, as the device can perfectly compute its best map coordinates, there is really no need to waste your time doing so. Nowadays, many GPS systems are able to work out map coordinates with a good precision. They can also provide you with useful information for your trip especially if you are heading to a place where you have never been. They can also download breaking news from a bunch of websites.

Due to the fact that GPS systems only work with longitude and latitude, you may need to know what these tenets stand for. You should also bear in mind that the map coordinates are worked out automatically by the device for you shortly when you switch your device on; therefore there is no need to reinvent the wheel! You will find that GPS systems are good travel companions.

Briefly speaking, coordinate systems are used to locate the position of an object in the space. The GPS technology makes use of longitude and latitude mathematical tenets to locate object in the space. Nowadays, many GPS devices offer the outstanding possibility to automatically compute the right GPS map coordinates for your specific destination. Therefore, there is no need to have excellent mathematical skills before enjoying your device. This is amazing, isn’t it?
