|A GPS signal receiver chip is an essential part of any tracking device.|
|The Global Positioning System (GPS) is used to pinpoint a device’s location anywhere on earth.|
The basic concept is that GPS satellites send signals to the earth, containing their position and the time the signal was sent. The receiver chip, which is a part of the tracker, takes this signal and analyses it.
Once the device has received a clear signal from at least four satellites, it can calculate its position.
Note: receiving GPS signals only permits the device’s owner to tell its location. Tracking requires the device to send its calculated position to an additional endpoint, such as a server.
If this connection is temporarily lost, the device can cache its data, and may send it once the connection is re-established, so no data loss may occur.
