The Current Status and Development on Refining GNSS Ephemeris by Means of Satellite Laser Ranging——Transmitting/receiving Issue(9) of GNSS Navigation Signals

卫星激光测距是校验导航卫星微波定轨的最佳外部基准,而被现行的GLONASS、北斗、Galileo、QZSS和IRNSS导航卫星所应用。本文综述了卫星激光测距用于GNSS星历精化的现况与发展,进而详细论述了激光定轨解算方法,及其对GNSS星历的精化。

Satellite laser ranging is the best external calibration for the microwave orbit determinations of the navigation satellites. Therefore it is used by the existing GLONASS,Bei Dou,Galileo,QZSS and IRNSS satellites. This paper summarizes the current status and development on refining GNSS ephemeris by means of satellite Laser ranging,and discusses in detail the resolving method for Laser orbit determinations and it refines GNSS ephemeris.
