Embodiment Construction
[0027] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.
[0028] The application of the method of joint inversion of the earth's gravity field using satellites with different orbital inclination angles:
[0029] Step 1: Satellite key payload data collection
[0030] (1) The inter-satellite distance ρ of a group of GRACE-A / B binary stars is collected by the space-borne K-band rangefinder 12 , interstellar speed and interstellar acceleration The orbital position of the double satellites is collected by the satellite-borne GPS receiver (r 1 ,r 2 ) and the orbital velocity of the binary star The non-conservative force (f 1 ,f 2 ).
[0031] (2) Use the numerical simulation formula of the 9th-order Runge-Kutta linear single-step method and the 12th-order Adams-Cowell linear multi-step method to obtain the reference orbit position of the binary star and binary reference orbital vel...
