ANALYSIS OF ACCELEROMETER PERFORMANCE PARAMETERS FOR SATELLITE GRAVITY GRADIOMETRY
摘要
Abstract
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 Lib 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.关键词
