| 摘 要： | 中国的全球卫星导航信号设计必须遵循许多约束条件,具备国际可协调性,导航信号的服务类型、载波中心频率、调制方式和伪随机码序列均需参加与GPS、Galileo进行的频率协调.依据参加与GPS频率协调的参考假设文件,描述了中国的全球卫星导航信号结构、基本参数、公开导航信号的伪随机扩频码序列和二次编码序列,计算表明伪随机扩频序列的性能与GPS信号伪随机扩频序列性能相当.

| 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 struc... |
