Abstract

This paper studied performance superiority of spread spectrum continuous phase modulation (SS-CPM) in navigation system, meanwhile, a new scheme-CPM-BOC modulation was designed based on the character of SS-CPM signal. The aspects of spectrum characteristic, code tracking accuracy, anti-multipath, and anti-interference were researched based on the parameters of compass and GPS typical signals. It is shown by theoretical analysis and simulation that SS-CPM modulation has better navigation performance compared with the classes of binary offset carrier (BOC) modulation, which is typical modulation in satellite navigation system. Finally, reference basis for the next generation satellite navigation signal waveform design was provided.

Key words： satellite navigation; continuous phase modulation; binary offset carrier; CPM-BOC; navigation performance
