A Review of the Optimization and Improvement Direction of BeiDou Satellite Navigation System Receiver

China has developed an independent satellite navigation system called BeiDou, which has become one of the 4 GNSS systems in the world. The receiver is a key component of the BeiDou system, and optimizing and improving its performance is crucial for ensuring stable operation and wide application. This paper provides a review of current optimization and improvement directions for BeiDou receivers, including a comprehensive optimization process, identifying shortcomings in current receivers, suggesting optimization directions, and discussing the use and maintenance of BeiDou GNSS receivers. This review aims to promote further research and development of BeiDou GNSS system receivers. Additionally, this paper will propose modifications to the GPS reception so that it can receive BeiDou signals.
