Research and Analysis of GNSS Performance Test Methods

GNSS performance test is necessary at various stages such as initial design, full operational capability and system modernization, and is also the important guarantee of GNSS continuous and reliable operation. At present, China's BeiDou navigation satellite system (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 studies the GNSS performance test projects carried out in the different stages of development in view of GPS, Galileo and some augmentation systems including WAAS, GBAS, EGNOS. And the test purpose, test content, test method, the experimental reference and test results are analyzed in detailed. Then, based on the status of China's BeiDou navigation satellite system, the related suggestions for performance test methods of BDS are put forward. The study is of great reference value to establishing BDS performance test environment and developing test methods.
