Embodiment Construction
[0066] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0067] The method for reducing the influence of gravity satellite barycenter adjustment error on the accuracy of the earth's gravity field includes the following steps:
[0068] Step 1: Acquisition of Gravity Satellite Measurement Data
[0069] (1) Obtain inter-satellite velocity data through the K-band range finder Obtain the double-satellite orbital position data through the satellite-borne GPS receiver (r 1 ,r 2 ) and binary star orbit velocity data Obtain the non-conservative force data acting on the binary star through the on-board accelerometer (f 1 ,f 2 ), get the angular velocity data Ω=(Ω x ,Ω y ,Ω z ).
[0070] (2) Binary satellite orbital position data (r 1 ,r 2 ) and binary star orbit velocity data Using the 9th-order Runge-Kutta linear single-step method and the 12th-order Adams-Cowell linear multi-step numerical simulation formula...
