| Abstract: | Taking the disturbing gravity vectors calculated by the earth gravity field model of EGM2008 in 360 degrees as the "true value",the computational results of Stokes integral model,the monolayer density model and the point-mass model are analyzed and compared.The results show that if taking account of the computational precision,the Stokes integral model is the best;if taking account of the computational velocity,the point-mass model is the best.In the specific computation,the proper model should be chosen according to the precision,velocity,parameters and the other requirements in the case. |
| Keywords: | trajectory disturbing gravity Stokes integral model point-mass model monolayer density model EGM2008 |
