An evaluation method research for evaluating navigation and position satellite effectiveness of supporting operational information 导航定位卫星作战信息支援效能评估方法研究
This thesis presents the acquisition method of synchronization codes and time mark codes under - 20db gaussian channel . then the total step length between initial state and current state can be calculated . basing on the step length , we can deduce the current state of pseudo - random codes , and implement the acquisition of the special pseudo - random codes 本文设计出时间标记码在信噪比达- 20dd时的捕获方案,在此基础上提出了由伪码历经的状态数,计算子码当前状态的方法,从而获得了在30秒内完成导航定位卫星信号直接捕获的方法与实现方案。
