Pretend you know how to do this: Take a digital camera and wire it to a global
positioning satellite receiver, and, for good measure, stick on a digital compass.
Not exact matches
Your tracking device would receive signals from the
satellites and then the
receiver would calculate the time it took to get the signals from each
satellite, check each
satellite's
position and come up with your location.
Once the
receiver locks on to the
satellite signals, a page appears showing your
position in degrees, minutes, and seconds of latitude and longitude.
With at least four
satellites in view, and hence four pseudo-ranges — the minimum for determining accurate location plus time — a GPS
receiver can compute its
position using basic trigonometry.
Because the signals arriving at a
receiver from all
satellites are measured at the same time, the distance measurements are all falsified by the same
receiver clock error, which must be calculated in order to determine an accurate
position.
Because of the high speed of light, it is necessary that the instant of signal transmission at the
satellite and the instant of signal reception at the
receivers antenna be accurately registered in order for the distance and, consequently, the
position calculation to be accurate.
Signals from
satellites orbiting the Earth transmit their
position and current time, which are then picked up by a GPS
receiver.
The image is based on sophisticated modeling of the distortion of radio signals between Global
Positioning System (GPS)
satellites and ground
receivers.

As you read this article, 24
satellites in six orbital paths are circling the earth twice a day, continuously transmitting coded positional and time information to GPS
receivers, which pick up the signals and use the coded information to calculate a
position in an earth co ‑ ordinate system.
