卫星测高术是７０年代发展起来的一项新技术，到目前为止国外已陆续发射了七颗载有高度计的卫星。高度计卫星定轨的精度对测高数据的应用有很大影响．本文概述了卫星高度计测高数据在海洋应用上的一些结果、影响轨道的因素、测轨方法和轨道精校正方法。最后根据现有卫星轨道校正数据得到卫星轨道误差与校正精度的关系式，据此分析了轨道计算误差对卫星高度计测高数据在海洋应用中的影响
Satellite altimetry is a new technology developed in 1970s, so far seven altimeter satellites have been launched abroad. The accuracy of altimeter satellite orbit determination has a great influence on the application of altimeter data. This paper summarizes some of the results of satellite altitude measurement data applications at sea, the orbital factors, orbital methods, and orbital correction methods. Finally, the relationship between the satellite orbit error and the correction accuracy is obtained based on the existing satellite orbit correction data. Based on this, the influence of orbit calculation error on satellite altitude measurement data in marine applications is analyzed
