Research on application of Beidou dual-mode receiver

Beidou dual-mode receiver has the functions of positioning, navigation, timing and message communication, and has been widely used in various industries. Based on the transition from the BDS-2 regional system to the BDS-3 global system, the impact of the upgrade of BDS on the service performance of the Beidou dual-mode receiver and the countermeasures are studied. Firstly, the differences between BDS-2 and BDS-3 in signal type, constellation scale and service performance are compared. Next the system composition and working principle of Beidou dual-mode receiver are briefly introduced. Then combined with the specific application scenario, the impact of the upgrade of BDS on the service performance of the Beidou dual-mode receiver are analyzed. Finally, the countermeasures of Beidou dual-mode receiver are discussed to reduce or eliminate the impact of BDS upgrade on the service performance of the receiver, and provide continuous and reliable services for users. The research results can provide reference for the design, development and application of Beidou dual-mode receivers.
