Abstract: With the development of compatibility and interoperability of global navigation satellite system, the implementation of satellite navigation receiving terminal with compatibility and interoperability performance is very important. In this paper, a dual frequency compatible and interoperable terminal is designed and implemented for CDMA navigation signal. The terminal parameters are set by terminal control software. The digital processing module is realized by general digital front-end module, parallel multi-channel acquisition based on time-domain, and multi-phase correlator, and the positioning function is further realized. The terminal has the characteristics of strong universality and fast acquisition speed, which lays a hard ware foundation for improving the continuity, integrity and availability of services.
