摘要:

北斗卫星导航系统作为我国自主建设、独立运行的全球卫星导航系统,目前已能够在亚太区域提供定位、导航和授时服务,并计划于2020年在全球范围内提供服务。随着目前卫星通信技术的飞速发展,卫星频率和轨位愈发拥挤,对北斗系统进行频谱保护性监测显得尤为重要。基于STK的轨道预报数据,收集了目前北斗卫星导航系统14颗非静止轨道卫星连续10日内对于我国9个城市的可视时间段数据,利用R语言对不同卫星及不同地点的监测可视时间进行了分组统计分析,并对不同监测地点进行了相似度分析。最后根据数据分析结果给出了初步选址建议。

Abstract:

BeiDou navigation satellite system (BDS) is a global navigation satellite system constructed and operated by China.At present,BDS is able to provide location,navigation and time service in Asia-Pacific,and will provide global service in 2020 as planned.As the fact of the rapid development of satellite communication technology,the spectrum and orbits of satellite are increasingly crowed.Therefore,it is vital to perform spectrum monitoring to BDS.Based on the STK orbital prediction data,the access time of the 14 non-GEO satellites in BDS to 9 Chinese cities in 10 days was collected.Group analysis according to different satellites and different cities,and similarity analysis within different cities were performed using the R programming language.At last,preliminary advices on site selection were provided according to the data analysis results.

Key words: BeiDou navigation satellite system, STK orbital prediction, monitoring station site selection
