转发GPS信号快捕及捕获策略研究

Research on Technique and Strategy of Fast Acquiring and Capture in GPS

由于转发测量方案具有适应动态范围大,可进行检前记录,捕获定位快等优点,故成为高消耗导弹试验的主要外测方案。对转发GPS信号的快速捕获定位一直是转发测量方案的关键技术之一,阐述了与转发GPS信号的快速捕获相关的一些技术措施及接收机捕获策略的制定。

For adapting high dynamic,record before demodulation and fast acquiring transmit pseudo -random noise codes, it becomes missile test of main exterior trajectory measurement means. Also it is one of the key technology about fast acquiring transmit pseudo-random noise codes in GPS, the paper expatiates some of measure about fast acquiring and strategy of receiver.
