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.
