A Performance Evaluation of Beidou Navigation Satellite System

According to the integrated test task of Beidou system,the evaluation methods and algorithms of system performance,such as service area,accuracy,continuity and availability are proposed.The results show that Beidou system is stable and reliable,and its positioning accuracy,continuity,availability are better than 20 m(95%),0.92/h and 90% respectively.From these results,it can be expected that the Beidou system can provide reliable and good quality PNT services in the future.
