Abstract

GNSS technology is used to monitor geological disasters and obtain deformation data in real time. In this paper, aiming at the problem of ephemeris anomaly in the real-time solution of GNSS, by calculating the single-point positioning solutions of ephemeris from different sources, taking the availability and accuracy index as the criteria, we can eliminate abnormal system ephemeris or abnormal satellites, effectively identify ephemeris problems, and screen out available ephemeris for monitoring and solving.
