摘要
针对北斗卫星导航系统易受干扰的问题,研究分析北斗卫星导航系统地面部分抗干扰策略:从分析系统抗干扰能力入手,重点从地面运控和应用系统2个层面研究干扰形式和相应抗干扰技术;并以地面站应用为例,在分析常用干扰监测技术的基础上形成3种干扰监测与定位方案;最后从技术和条件建设2个维度提出应对干扰问题的几点思考和对策,为地面站平时做好管理维护提供参考,为主管部门提高北斗卫星导航系统复杂环境下服务保障精度提供借鉴。
Aiming at the problem that BeiDou navigation satellite system(BDS)is vulnerable to interference,the paper studied on the anti-jamming strategy of BDS ground part:the anti-interference ability of the system was analyzed,and the interference forms and corresponding anti-interference technologies were mainly studied from two levels of ground operation control and application systems;then,taking the application of ground stations as an example,three interference monitoring and positioning schemes were proposed based on the analysis of common interference monitoring technologies;finally,some thoughts and countermeasures to deal with interference problems were put forward from two dimensions of technology and condition construction,which could provide references for the management and maintenance of ground stations at ordinary times,and for the competent authorities to improve the service guarantee accuracy of BDS in a complex environment.
