what gps ?

Question

what is gps?how it work

Answer 1

The Global Positioning System triangulates and then correlates a fixed position on earth then transmits the data to a receiver. This is the basis of GPS.
LORAN was widely used before GPS and it was on the same Triangulation Fixed Point.
GPS is superior as the signal comes from satellites and the data can be received almost anywhere on the face of the Planet Earth.

Answer 2

The Global Positioning System (GPS), is currently the only fully functional Global Navigation Satellite System (GNSS). More than two dozen GPS satellites are in medium Earth orbit, transmitting signals allowing GPS receivers to determine the receiver's location, speed and direction.

Since the first experimental satellite was launched in 1978, GPS has become an indispensable aid to navigation around the world, and an important tool for map-making and land surveying. GPS also provides a precise time reference used in many applications including scientific study of earthquakes, and synchronization of telecommunications networks.

Developed by the United States Department of Defense, it is officially named NAVSTAR GPS (NAVigation Satellite Timing And Ranging Global Positioning System). The satellite constellation is managed by the United States Air Force 50th Space Wing. Although the cost of maintaining the system is approximately US$400 million per year, including the replacement of aging satellites, GPS is free for civilian use as a public good.

Answer 4

GPS is Global positioning System. It works through satellites.

Answer 5

Hi
gps is also known as ground positioning system is an electronic device works with the help of satelite. It is used in finding routes while we are travelling, identifying different parts of earth/land on our computer and much more about this.

Answer 6

Global Positioning System. It works by having satellites in the sky locate a specific device. The way in which it is done is by using multiple satellites and pinpointing the location by triangulating it.

Answer 7

global positioning system. they use satellites to track exactly where you are on the earth and help you find where you need to go.
