Benefits and Application of a GPS System in Google Earth
The different possibilities offered by the GPS system are greatly appreciated by the consumers. This article will let you know what exactly is a GPS, its working, current uses and how they have benefited the market. New applications are of course developing all the time as the science and techniques are advancing day by day.
GPS stands for Global Positioning System that was originally considered as a navigation aid for military. GPS offers you a set of co-ordinates that represents the position of the GPS unit in consideration with its longitude, latitude and its elevation on the planet Earth. It also shows you the time that is accurate like that of an atomic clock. The applications of the GPS technology resulting in navigation systems are the GPS surveying, GPS mapping and GP tracking systems. GPS has the ability to receive the satellite signals and calculate their positional information.
Now let us see how does the GPS system actually works?
The primary principle of GPS is very simple to understand as it produces the same results like that of traditional triangulation, but it does not use angles in any of its functioning. If you imagine an orienteer who wants to locate himself on the map, here the GOPS will replace the known points with the satellites and the azimuth with the time required for the signal for traveling form all the known points to the GPS receiver. This makes the system work roughly wherever it is located. The circles represents the distance from the satellite, calculate it on the basis of travel time of the signal and finally intersects.
For this, the GPS locator should have the same co-ordinated time like that of the satellites on the atomic clocks. For this, it cross checks the intersection of the 3 circles with the4th one that is taken form another satellite. The easiest application in the GPS system is the GPS tracking device. It located itself with the other related communication technologies like telephones and radio transmissions. A tracking device contains GPS software, a GPS user and associated co-ordinates. For example, a GP watch makes use of the radio waves to transfer its location to a tracking center; whereas the GPS phones utilize the current technology of the cell phones.
The GPS vehicle tracking are used generally to find out the stolen cars of offer some services to the driver like finding out the gas station in the close-by area. Even police are benefitted from this technology. They use the GPS devices to make sure that curfew is not violated by the parolees and also to find them out, if they do so. Then, GPS system helps you to navigate your trips. You may enter a particular destination of your interest and this system will show you the way from where to get in form where you are and where you intend to go. This gradually saves your extra time and money spent on gas that you can otherwise spend on if you lose your way and are forced to find your own path.
