由于GRACE Follow-On双星系统等效于基线长为星间距离的一维水平重力梯度仪，因此本文基于GRACE Follow-On卫星重力梯度法开展了精确和快速反演下一代地球重力场的可行性论证研究. 研究结果表明：第一，基于GRACE Follow-On卫星重力梯度法（GFO-SGGM），利用卫星轨道参数（轨道高度250 km、星间距离50 km、轨道倾角89°、轨道离心率0.001）、关键载荷测量...
本文基于星间加速度法开展了插值公式、相关系数和采样间隔对GRACE Follow-On星间加速度精度影响的研究. 模拟结果表明:1)适当增加数值微分公式的插值点数可有效提高插值精度. 基于9点Newton插值公式,星间加速度的插值误差为4.401×10-13 m·s-2,分别基于7点、5点和3点插值公式,插值误差增加了1.192倍、6.912倍和274.029倍. 2)适当增大相关系数可有效降低星...
本文利用轨道扰动引力谱分析的方法有效估计了未来GRACE（Gravity Recovery And Climate Experiment）Follow-On卫星反演地球重力场的空间分辨率。基于GRACE Follow-On卫星的轨道特性，从垂直和水平两个方面计算了其在高空所受到的扰动引力谱，并根据谱特性及星载加速度计的测量噪声水平分析了该卫星能反演重力场的阶数。利用EGM96重力场模型分别计算了2...
