GNSS性能测试方法研究与分析

Research and analysis of GNSS performance test methods

针对GNSS的性能测试对卫星导航系统连续、可靠运行非常重要,而目前可借鉴的研究成果较少的问题,提出我国的BDS在处于区域导航系统向全球导航系统建设发展的过渡阶段,需要开展的系统相关性能测试的方法:首先针对GPS、Galileo、GLONASS及包括WAAS、EGNOS在内的各增强系统,阐述了GNSS在建设发展的不同阶段开展的性能测试试验项目,重点分析了性能测试的试验目的、试验内容、试验方法、试验基准以及试验结果等,给出了该阶段BDS性能测试试验方法研究的相关建议。

GNSS performance test is necessary at various stages such as full operational capability and reliable operation.And the current research results on GNSS performance test are less.The methods of performance test for China＇s BeiDou navigation satellite system（BDS）were proposed.At present,BDS is in the construction stage of developing from the regional navigation system to the global navigation system,which is quite vital to carry out the study on relevant performance test methods.Firstly,this paper systematically studied the GNSS performance test projects carried out in the different stages of development in view of the GPS,Galileo,GLONASS of Russia and augmentation systems including WAAS,GBAS,EGNOS.And the test purpose,test content,test method,the experimental reference and results were analyzed in detailed.Then,based on the status of China＇s BeiDou navigation satellite system,the related suggestions for performance test methods of BDS were put forward.The study is of important referential value to the establishment of BDS performance test environment and test methods research.
