Application of IGS Ultra Rapid Products to Real-Time Tropospheric Monitoring

  • Through comparing the accuracy and latency of broadcast ephemeris and three kinds of precise ephemeris provided by IGS(the International GPS Service),it was found that only IGS ultra rapid products(IGU) can meet the need for time of tropospheric monitoring.Based on the above recognition and by analyzing the precision of satellite orbits and clocks of IGU,a method integrating orbit relaxation with orbit quality index weighting was proposed and tested using data from four GPS reference stations in GPSNOS(GPS reference station network of Sichuan).The tested result shows that the proposed method can solve the uncertainty of IGU to effectively apply IGU to real-time tropospheric monitoring.
