Abstract:

It is an important way for improving the application of Beidou system on general aviation to conduct service performance 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 difference 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 correlation 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.

Key words: Beidou RDSS, general aviation surveillance, flight test, service performance
