    Abstract
  • The satellite navigation signals have inherent vulnerabilities and are highly susceptible to both intentional and unintentional electromagnetic interference. Therefore, conducting monitoring and evaluation of satellite navigation service performance and interference signals is of significant importance for supporting the operational services of navigation systems and ensuring the security of spatio-temporal information applications. This paper addresses the mechanisms and characteristics of monitoring and evaluating satellite navigation service performance. In conjunction with the practical needs for interference monitoring and troubleshooting, it presents an overall architecture for system construction and operational processes. Furthermore, it conducts research and analysis on the key technologies necessary for enhancing system effectiveness, providing comprehensive guidance and technical support for the engineering construction of a navigation application monitoring and support system characterized by “multi-source integration, wide-area coverage, three-dimensional perception, and rapid response”.
