Star sensor aberration compensation method

The invention relates to the technical field of aberration compensation, in particular to a aberration compensation method for a star sensor. Comprising the following steps: acquiring at least three groups of earth centroid velocities of ground injection closest to a current moment at a set moment so as to calculate the earth centroid velocity at the current moment; wherein the earth centroid velocity is the earth centroid velocity corresponding to a set moment under a J2000 coordinate system periodically injected according to an astronomical calendar; calculating the satellite speed at the current moment based on the satellite speed under the J2000 coordinate system measured by a GPS (Global Positioning System); wherein the GPS measurement period is greater than the update period of the aberration compensation amount; and calculating the aberration compensation amount at the current moment based on the earth centroid velocity and the satellite velocity at the current moment. According to the scheme, the calc
