Satellite-based Positioning, Navigation, and Timing (PNT)

Abstract

The Global Positioning System (GPS) is a satellite-based radio navigation system that uses multiple satellites in view of a receiver on earth to produce precise positioning based on signal propagation speed, distance to the satellites, and precise time. This paper describes the different segments of the GPS: Space, Control, and User. We also discuss the measurements that determine precise location information. Additionally, we discuss the radio signal and factors of interference. Finally, we conclude with use cases for modern applications of GPS.
