| 摘 要： | 推导了一组测高卫星轨道设计的理论公式，介绍了相关方法，并编写了一套软件。分别以激光测高卫星ICESat和雷达测高卫星HY-2A为例，基于31阶地球带谐重力场，给出了其平均轨道参数与密切轨道参数。轨道模拟显示，卫星经过各自的回归周期之后，其星下点均能精确回到初始位置，并且长半轴、轨道倾角、偏心率和近地点幅角均没有发生长期和长周期的变化，符合参考轨道要求。

| Abstract: | The orbits of altimetry satellites should be repeat groundtrack and frozen. We derive an algorithm of the orbit design based on zonal geopotential field and develop the software by ourselves. This paper takes ICESat and HY-2A as examples, computing their mean orbit elements and osculation orbit elements. The orbit generation results show that the satellites can get a nice closure after a full cycle and there is no secular and long period change for the semi-major, eccentricity, inclination and the argument of perigee. The orbit can meet the requirement of altimetry satellites and can be taken as a reference orbit. |
