The new generation of navigating and positioning system which used a more effective BOC modulation, has more advantages such as smaller crosstalk with BPSK, anti-fading ability etc. This paper describes the principle, performance of binary offset carrier (BOC) modulation, and the characteristics of spread spectrum signal; it analyzes the highly efficient method of acquisition and code tracking, which provides a new train of thought for enhancing signal acquisition speed, effectively reducing the probability of the wrong lock and saving hardware cost.
