| Abstract: | The causes of aliasing in GRACE mission is investigated,the impact on the static as well as time-varying gravity field is analysed,and a method for analyzing aliasing problems relative to ocean tide and atmosphere is proposed.Through comparing different methods for reducing aliasing error,it is pointed that gravity field mearsuring mode with combination of satellite costellations is the most effective one at present.The results will be able to provide references for the development of next generation gravit... |
