北斗RDSS通航监视服务性能测试研究

Study on service performance test of Beidou RDSS in general aviation surveillance

开展北斗RDSS通航运行监视服务性能测试是推动北斗通航服务应用的重要途径。运用当前北斗用户终端及地面指挥机系统,选取Y-12通航机型,开展了覆盖全国不同纬度、不同机载设备安装方法、包含各个飞行阶段的飞行监视测试,以北斗RDSS位置报告数据接收成功率为指标,分析了纬度、安装方案及飞行阶段对监视性能影响特征。结果显示,不同纬度区域特征下成功率未呈现显著差异,安装方案对成功率具有显著影响,当天线安装于飞机顶部时成功率最高,不同飞行阶段下成功率未出现明显差异。表明北斗RDSS在不同纬度区域以及不同飞行阶段下具有同等监视服务性能,而机载设备天线的安装位置与监视性能息息相关。并基于监视性能探讨了针对不同用户的北斗RDSS通航监视服务性能水平,说明了北斗系统用于通航运行监视的潜力。

It is an important way for improving the application of Beidou system on general aviation to conduct service per- formance test of Beidou RDSS applied in running surveillance. Beidou user terminals and its command system are used and Y-12 general aviation plane is chosen to carry out the tests. The flight tests includes different latitudes, different installation methods of airborne equipment and different flight, stages. The success rate of position report data receiving of Beidou RDSS is used as the index to analyze the effect characteristics of latitude, installation method and flight stage on the surveillance performance. Analyzing results show that there is no significant diffe- rence for success rate in different latitude areas. The installation method has significant effect on the success rate and when the antenna is installed on the top of the plane, the success rate reaches the highest. There is no obvious difference for success rate in each flight stage. It can be concluded that Beidou RDSS possesses equivalent surveillance service performance in different latitude areas and flight stages, but the performance is of high corre- lation with the installation place of antenna. Based on the performance, the service level of Beidou RDSS for each user is discussed to illustrate the potential of Beidou system applied in the surveillance of general aviation.
