Summary: | A multipurpose star simulator driving method for star sensor simulation testing comprises the following steps: S1, setting a base quaternion shown in the description, an attitude maneuver angular rateomega, the number N of generated driving data beats and data updating rate freq; S2, calculating step size step according to the attitude maneuver angular rate omega and the data updating rate freq;S3, setting an initial pointing region (ra, de), judging an exposure mode of a star sensor, and generating rotational quaternions of optical heads under each driving data beat according to the initialpointing region (ra, de) and the step size step; S4, generating base kinetic quaternions of the optical heads under each driving data beat according to the base quaternion shown in the description and the rotational quaternions of the optical heads; S5, judging whether the base kinetic quaternions of the optical heads under each driving data beat are generated, returning to S3 if generating is not finished, otherwise, gene |
