文摘This paper deals with the recent advances in global positioning system(GPS). First of all,the principal error sources of GPS observations are analysed. Then the scientific applications of space based GPS are described,of which the TOPEX and Microlape missions are excellent examples of great success. With regard to the application of GPS to meteorology (GPS/MET),detailed description is given to earth based GPS/MET and space based GPS/MET,they stand at the front of recent advances in GPS.
