自主海洋测高卫星串飞模式的设计与重力场反演精度分析
|
Abstract:
根据自主海洋测高卫星发展需求，设计了双星串飞运行模式，该运行模式下2.3 a时间可满足全球海洋区域1'×1'分辨率的地面轨迹覆盖要求。首先，将测高卫星重力场反演分为不考虑轨道运行特点（思路1）和考虑串飞轨道运行特点（思路2）两种思路，利用逆Vening-Meinesz方法开展了正态分布下随机误差传播的仿真计算，获得了两种思路下对应的误差指标。以该误差指标为基础，分别计算了双星串飞模式下两种重力场反演思路对应的精度指标。其中，反演思路2充分利用了串飞模式双星东西方向地面观测值可以进行相对定轨的特点，并考虑到近距离条件下传播误差、地球物理改正误差的系统误差特性，因此反演思路2的垂线偏差精度较反演思路1有了一定的提高，其重力场反演也具有一定的优势。理论计算结果表明，利用思路1的反演方法，2.3 a时间可获得1'×1'重力异常精度为6~10 mGal，4.6 a时间可达到4.2~7.1 mGal；利用思路2的反演方法，2.3 a时间可获得1'×1'重力异常精度为3.9 mGal，4.6 a时间可达到2.8 mGal
