卫星导航系统信号格式日益多样化,在高精度测量型接收机中几乎要接收和处理所有卫星导航系统信号,因此实现兼容性极强且高效的捕获模块非常有必要。为了解决多系统多频点的兼容型捕获问题,同时考虑到捕获速度和资源限制,在原基础上提出了一种新的捕获模块设计方案,解决了兼容性问题并大幅度提升了捕获速度。根据算法模型完成了仿真实现,并在高精度测量型接收机板卡上进行了实际验证,满足捕获当前所有卫星导航信号的要求,同时还可以兼容捕获未来的北斗全球系统信号。
衛星導航繫統信號格式日益多樣化,在高精度測量型接收機中幾乎要接收和處理所有衛星導航繫統信號,因此實現兼容性極彊且高效的捕穫模塊非常有必要。為瞭解決多繫統多頻點的兼容型捕穫問題,同時攷慮到捕穫速度和資源限製,在原基礎上提齣瞭一種新的捕穫模塊設計方案,解決瞭兼容性問題併大幅度提升瞭捕穫速度。根據算法模型完成瞭倣真實現,併在高精度測量型接收機闆卡上進行瞭實際驗證,滿足捕穫噹前所有衛星導航信號的要求,同時還可以兼容捕穫未來的北鬥全毬繫統信號。

With the development of multi?mode satellite navigation signals,it is necessary to design a kind of acquisition module with extreme compatibility because almost all of current satellite navigation signals need to be received especially in the receivers for high?accuracy measurement.In order to solve the problem of multi?mode compatibility for acquisition,in view of acquisition speed and resource limitation,this paper proposes a new method acquisition algorithm based on traditional acquisition module.This method resolves the compatibility problem and improves acquisition speed. The simulation results show that this method can be used in high?accuracy receiver,and satisfy all acquisition requirements of current satellite navigation signals and BDS global signals in the future.
