The American scientists brought forward the proposal of sounding the Earth′s atmosphere by GPS system in the 1980′s,and GPS Meteorology(GPS/MET) was born then.GPS Meteorology is made up of ground based GPS/MET and space based GPS/MET.Ground based GPS/MET has come to the phase operationally applied with net in many countries of the world.Space based GPS/MET has also made a great progress.The paper introduces the development history and sounding principal of space based GPS/MET.Then the latest advancement in the field of GPS-LEO occultation data processing and application has been analyzed.And a review and summarization of GPS-LEO occultation sounding research in our country was given.At last an outlook of GPS-LEO future development was put forward.
