中国全球卫星导航信号基本框架设计
Research on COMPASS Navigation Signals of China
摘要
Abstract
The signals of global navigation satellite system of China must obey many constraints, and should be coordinated with other navigation signals as well. The service type, carrier frequency, modulation scheme and spreading codes are essential for the coordination. The signal structure and parameters of COMPASS excerpted from the reference assumptions document (RAD) were presented. The correlation performances of the spreading codes of the COMPASS open signals were consistent with that of GPS. Base on the signal structure and basic parameters of the RADs, COMPASS and GPS, the L band frequency coordination was completed in accordance with the frames established by ITU in September, 2010.关键词
