How can a GPS help you find your location on earth?

Answer 1

By transmitting signals to satellites that locate us

Answer 2

That would depend on what you use it for, for a private party you could use it to locate any place in the world you wanted to visit or track, locate and recover a stolen vehicle you own. A business would use it for asset management, where they would keep track of mobile and stationary assets, track vehicle or freight locations as well as monthly reporting that helps save revenue. Whether it is the stolen vehicle, lost child or hiker or just for tracking and managing assets, GPS has been a very useful technology.

Answer 3

A GPS (Global Positioning System) constellation consists of about 24 satellites circling the Earth, plus a few spares to allow for breakdowns etc. Each satellite is equipped with a high precision atomic clock which emits a signal of high accuracy.

There is a similar Glonass system operated by Russia, and the European Union is commissioning another system named Galileo.

A person with an appropriate receiver, may listen out to these satellites, and provided there are at least four satellites overhead, then the position of the receiver on the Earth's surface may be calculated to a small accuracy. Depending on the receiver apparatus, resolution of a few mm may be obtained, though with hand-held apparatus, a few metres is more usual.

The signal may be degraded by the signal being close to the horizon, or by the receiver being in a canyon such as in a city or mountains. Forest cover will also degrade the accuracy.

Answer 4

The GPS receiver, receives time signals from satellites overhead.

The difference in time, for the signal to reach the receiver on earth, will be different from each satellite and can be measured.

The time differences are applied to a mathematical formula and give the position on earth, in three dimensions (height as well).

Additional information from the satellites will identify each one.

An almanac built into the receiver, will determine where each satellite is in the sky. (or where they should be)

This positional information is used in the calculation and the time difference signals applied to it.

The system is passive. The GPS receiver does not transmit or communicate in any way with the satellites. It listens only.

The atomic clocks onboard each satellite are monitored from earth and kept in synchronization.

Answer 5

=GPS can find your place on earth by sending radio signals to receivers on earth.=

Answer 6

it helps find new places. it also helps us when we're lost. it saves our money by nothing roaming around and burning gas.it is really helpful

Answer 7

not really sometimes it could take to different places

Answer 8

Because it uses a GIS algorithm that calculates the lattitude, longitude and distance of a location on Earth.

Answer 9

It helps you find local thrift stores
