The receiver design of Beidou navigation system based on ZYNQ chip

Beidou navigation system is a global positioning and navigation system, which is independently developed by China, and it has been widely used in many fields. A novel receiver system for Beidou navigation system is introduced in this paper, basing on ZYNQ chip. ZYNQ chip includes two functional modules-PL and PS: the PL part completes the functions of acquisition, tracking, navigation message demodulation and decoding, original observation and measurement, etc., and can output navigation message, original observation and other information through the data bus interface; the PS part implements the solution of user position, speed, time, etc. (PVT) information. Each section of the receiver is designed in detail. The whole system has the advantages of high integration and flexibility, which is very suitable for the development and testing of the Beidou receiving system.
