Gps Setup - Getac M220 Operation Manual

Here's how GPS works in five logical steps:
The basis of GPS is "triangulation" from satellites.
To "triangulate," a GPS receiver measures distance using the travel
time of radio signals.
To measure travel time, GPS needs very accurate timing that it
achieves with some tricks.
Along with distance, you need to know exactly where the satellites
are in space. High orbits and careful monitoring are the secret.
Finally you must correct for any delays the signal experiences as it
travels through the atmosphere.
Five broad categories of GPS application:
Location – determining a basic position
Navigation – getting from one location to another
Tracking – monitoring the movement of people and things
Mapping – creating maps of the world
Timing – bringing precise timing to the world
Turning Off/On the GPS
Your computer has a built-in Fn+F12 GPS hot key to switch the GPS
on/off (see "Hot Keys" in chapter 2).
