我国全球卫星导航信号应具有较大的信号带宽,其公开导航信号可与GPS,Galileo和GLONASS公开导航信号实现互操作,授权导航信号可与GPS和Galileo授权导航信号实现射频兼容共存,互不影响性能.设置导频信号以利于接收机捕获、跟踪,提高测量精度.全球卫星导航信号还应具有抗干扰,防欺骗能力.提出了一种关于我国全球卫星导航信号结构的方案. China’s global satellite navigation signal should have a larger signal bandwidth, its public navigation signal with GPS, Galileo and GLONASS public navigation signals to achieve interoperability, authorized navigation signals and GPS and Galileo authorized navigation signals to achieve RF compatible coexistence, without affecting each other Set the pilot signal to facilitate the receiver to capture, track, improve the measurement accuracy.Global satellite navigation signal should also have anti-jamming, anti-cheat ability.A solution for China’s global satellite navigation signal structure.
