卫星导航信号存在固有脆弱性,极易受到有意或无意的电磁干扰,因此开展卫星导航服务性能和干扰信号的监测与评估,对支持导航系统运行服务和保障时空信息应用安全具有重要意义.本文针对卫星导航服务性能监测评估的机理特点,结合干扰监测排查的现实需求,给出了系统建设的总体架构和运行的机制流程,并就系统效能发挥的关键技术进行研究分析,为工程化构建"多源融合、广域覆盖,立体感知、快速响应"的导航应用监测保障系统提供总体指导和技术支撑.
Design of satellite navigation service performance evaluation and interference monitoring protection system
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".
