Design and Implementation of Beidou/GPS Dual Mode Receiver

摘要

With the development of global satellite navigation systems, the design of multi-mode navigation receivers based on software radio has become a research hotspot in the entire navigation system. The design of a Beidou/GPS dual-mode receiver based on the MAX2769B is introduced. The architecture of the FPGA+ARM is used to process satellite signals and finally achieve navigation positioning. It can be seen from the experiment that based on the Beidou/GPS dual-mode receiver, more observations are added on the basis of constellation optimization, which significantly reduces the positioning error and improves the positioning accuracy.
