摘要
首先分析了 GPS观测的主要误差源。其次 ,叙述了空基 (星载 ) GPS的科学应用 ,其中 TOPEX和 Micro L abe任务都是成功的范例。关于 GPS对于气象学的应用 (GPS/MET)方面 ,比较详细地介绍了地基 GPS/MET和空基(星载 ) GPS/MET的最新进展 ,二者处于 GPS的最新进展的前沿。
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 missons are excellent examples of great success. With regard to the application of GPS to meterorology (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.
