What is AGPS Tracker?

Assisted GPS or Augmented GPS (abbreviated generally as A-GPS and less commonly as aGPS) is a system that often significantly improves the startup performance—i.e., time-to-first-fix (TTFF)—of a GPS satellite-based positioning system.

How accurate is AGPS?

There continues to be improvement, and you'll see indoor accuracy of better than 10 meters, but round-trip time (RTT) is the technology that will take us to the one-meter level. ...

How far can a GPS tracker work?

Ultimately, most GPS tracking devices are accurate to within three meters, allowing users to have fairly accurate location information.

Can GPS be tracked?
