Summary

This chapter discusses the Doppler shift due to the relative motion of the satellite and the user terminal, and go on to show how this shift can be used to locate a transmitter beacon. It focuses on the concepts behind ranging from satellites - that is, measuring the user's range from various satellites. The chapter describes the concepts behind ranging from satellites that is, measuring the user's range from various satellites. It explains the basic concepts behind code-phase (time) measurements and discusses how multiple pseudorange measurements, together with knowledge of the satellite positions, may be used to establish an estimate of the user's position. Finally, the ultimate in positional accuracy is to be obtained using carrier phase measurements as opposed to code-phase measurements. The measurement of carrier phase is not without problems, and these are briefly outlined.
