Performance Evaluation of the Initial Service of Galileo High Accuracy Service
Abstract This paper comprehensively analyzes the performance of high accuracy service(HAS) from the aspects of service correction availability, track accuracy, clock correction accuracy, and so on. At the same time, we analyze the performance of HAS PPP using MGEX stations in different regions of the world. The results show that the availability of most satellite corrections is at least 80%. Signal-in-space ranging error(SISRE) of GPS and Galileo are 0.163 m and 0.097 m, respectively. The accuracy of MGEX stations is less than 0.2 m in the horizontal direction and 0.4 m in the vertical direction.
Key words :
HAS
correction accuracy
positioning performance
real-time precise point positioning
