Can GPS signals be tracked?

The government's GPS satellites are one-way beacons that cannot track you or anything on the ground. But commercially available GPS devices with communication or recording features can help users keep track of everything from vehicles and cargo to people and animals.

How does GPS tracking work?

GPS trackers connect to a series of satellites to determine location. The tracker uses a process called trilateration which uses the position of three or more satellites from the Global Navigation Satellite System (GNSS) network and its distance from them to determine latitude, longitude, elevation, and time.

What signal do GPS trackers use?

GPS tracking system technology uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction.

What are the two types of GPS signals?

Signals. Each GPS satellite transmits data on two frequencies, L1 (1575.42 Mhz) and L2 (1227.60 MHz). The atomic clocks aboard the satellite produces the fundamental L-band frequency, 10.23 Mhz.
