what is the meaning of GPS?

Question

This is a kind of computer terminology which shows or indicate a position of something.

Answer 1

Global Positioning System, I think

It uses orbiting satellites to triangulate your location

Answer 2

GPS means Global Positioning System. It is a satellite navigation system.
It has an space segment, a control segment and a user segment.
The nominal GPS Operational Constellation consists of 24 satellites that orbit the earth in 12 hours. There are often more than 24 operational satellites as new ones are launched to replace older satellites.
The Control Segment consists of a system of tracking stations located around the world.
The GPS User Segment consists of the GPS receivers and the user community. GPS receivers convert SV signals into position, velocity, and time estimates. Four satellites are required to compute the four dimensions of X, Y, Z (position) and Time. GPS receivers are used for navigation, positioning, time dissemination, and other research.
If the receiver does not "see" the four satellites, the position could be wrong.

Answer 3

The Global Positioning System (GPS), is currently the only fully-functional satellite navigation system. 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

Global Positioning System (GPS) is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations.

GPS uses these "man-made stars" as reference points to calculate positions accurate to a matter of meters. In fact, with advanced forms of GPS you can make measurements to better than a centimeter!

In a sense it's like giving every square meter on the planet a unique address.

GPS receivers have been miniaturized to just a few integrated circuits and so are becoming very economical. And that makes the technology accessible to virtually everyone.

These days GPS is finding its way into cars, boats, planes, construction equipment, movie making gear, farm machinery, even laptop computers.

Soon GPS will become almost as basic as the telephone. Indeed, at Trimble, we think it just may become a universal utility.

Answer 5

Global Positioning Satellite

Answer 6

It stands for Global Positioning System.

At any one time there are several satellits in the sky overhead, the precise position of which is known. A GPS system will lock onto 3 or more satellites and can then work exactly where on the planet it is. It works anywhere there is a clear view of the sky. Indoors, in dense woodland, or on city streets hemmed in by tall buildings the GPS receiver may not be able to lock onto enough satellites to provide a reading.

Originally used by mariners and pilots the technology in recent years has become more readily available and is used in sat-nav systems and by anyone who wants to know where they are.

The worldwide GPS system is controlled by the US military. For military purposes (e.g. smart bombs) the accuracy is down to a few centimetres but for civilian purposes it's restricted to within a few metres (until about 5 years ago it was restricted to 100 metres).

Answer 7

Global Positioning System

Answer 8

GPS Stands for Global Positioning System. It uses military sattelites to triangulate your position on earth (or above it as airplanes do) top end recievers are usually accurate to about six feet.

Answer 9

global positioning system.
from the way you categorized this question, i would assume it is on your cell phone. this enables security crews to reach you if you call and cannot be located. also, it just means that you can log onto the internet. basically that you are able to connect, not that you are connected. hope this answered your question! :)

Answer 10

global positioning system.
can be in vehicles, or hand-held.
in cars used for directions and hand things like hiking.
