摘要 根据梯度测量原理并结合GOCE重力梯度卫星的在轨L1b实测数据,分析了静电悬浮加速度计分辨率、标度因数与二次项系数对梯度测量的影响。在此基础上建议,未来卫星重力梯度测量计划需选用更高精度的加速度计和采用三轴无拖曳控制技术。 Space-borne gravity gradiometer is a core sensor in satellite gradiometry,and accelerometer is the basic unit of gravity gradiometer,whose performance directly affects the level of gravity field recovery and space resolution.Combined the basic operation principle with the real L1b data of the satellite gradiometry mission GOCE,the effects of the resolution,scale factor and quadratic factor of accelerometers are specified in this paper.On the basis of analysis results,finally,we propose that the higher sensitive accelerometers and three-axis drag-free control technologies should be developed and applied into the future satellite gradiometry mission.
