GPS Receiver Hardware Fundamentals

Abstract

This chapter presents a broad overviewof the hardware behind an analogimplementation of a GPS receiver. The hardware’s goal is to get the SV data, replicate the SV clock, properly “set” the replica clock and make the “time sent” and “time received” measurements to achieve the goal of computing user position. The functions of Doppler Scan/Track, C/A Code Scan/Track, and data clock recovery are introduced and discussed here, as they are not typical to conventional narrow band receivers. Chapter 7 will focus on the details of the hardware subsystems presented in this chapter.
