With the gradual promotion of the application of the Beidou-3 system, the Beidou RDSS function is increasinglywidely used in industries such as border defense, meteorology, transportation, aviation, and emergency search and rescue. Therefore,monitoring the performance of Beidou RDSS is an important way to promote the application of Beidou RDSS services. A systemimplementation method for real-time monitoring of Beidou-3 RDSS performance is designed. The system is built with security, highreliability, and scalability. The system meets the basic support requirements of various functions such as data reception, collection,storage, processing, management and monitoring. The performance evaluation content of RDSS has been designed, includingcommunication content, received signal type, number and power of signals, communication success rate, positioning accuracy,communication delay and other functional indicators. Finally, the feasibility of the scheme is verified by analyzing the test result datathrough the actual test verification under the natural environment conditions. The proposed solution in this article has thecharacteristics of strong real-time monitoring, continuous monitoring, timely warning, and remote push of RDSS performance. It canpush relevant information to relevant users through the network, enabling users to conveniently and quickly grasp the performance ofRDSS, providing guarantee for users' RDSS applications.
