COMPASS/CAPS组合导航接收机设计与实现

Design and Implementation of COMPASS/CAPS-Based Integrated Navigation Receiver

COMPASS系统和CAPS系统作为我国自主研发的卫星导航系统,它们在实际使用时具有较强互补的特性。本文研究了COMPASS系统和CAPS系统的特点,利用CAPS系统和COMPASS系统的特性设计了COMPASS/CAPS接收机,详细给出捕获、跟踪算法设计,并对设计的接收机进行了测试。测试表明,设计的COMPASS/CAPS接收机性能良好,相对单COMPASS系统,COMPASS/CAPS接收机在抗干扰特性,特定的应用场合上的功能和性能有了较大的提高。

As an innovative system on our own, the COMPASS navigation system and the CAPS navigation system complement each other perfectly in practical applications. The COMPASS/CAPS-based receiver is designed based on the characteristics of COMPASS and CAPS system described in the paper. The acquisition and tracking algorithm are presented and the test of the receiver is implemented. The test result shows that the COMPASS/CAPS-based receiver has higher performance and more perfect functions, in such special applications as anti-jamming, than a single COMPASS system receiver.
