【摘要】 本文利用频谱分析和模拟仿真两种方法,对低低卫星-卫星跟踪(SST-LL)数据反演重力场的精度进行了分析。通过建立模型观测量与有效载荷直接观测量的关系,对SST-LL主要有效载荷的测量精度需求进行了初步论证。
【Abstract】 On the basis of spectral analysis and simulation computation, the error analysis on gravity field recovery from SST-LL data is presented. By use of the relation between model-observation and direct observation, the measuring accuracy demand on primary payload is discussed.
