Embodiment Construction
[0056] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
[0057] In the prior art, the two-pulse maneuver that only applies lateral thrust is often used to adjust the fixed-point position of the stationary orbit. The first lateral pulse along the lateral direction of the track can change the semi-major axis to reduce the longitude deviation; the second pulse is at the fixed-point position. Applied at the end of the adjustment to eliminate the longitude drift rate. During the long-term fixed-point position adjustment process of the stationary orbit, the field harmonic perturbation...
