The invention relates to an on-orbit high-reliability calibration wheel motor control method and satellite-borne software, belongs to the technical field of satellite platforms and satellite-borne software, and solves the problems that a calibration wheel can be reliably and accurately replaced to a target position every time within a task period of a remote sensing instrument and the service life requirement of a calibration wheel motor is met. The control method specifically comprises the following steps: quantifying the positions of hole sites and magnetic steel on two Hall sensors and a calibration wheel; obtaining a target position and a correction step number of the calibration wheel; if the current position of the calibration wheel is unknown or the target position is a positioning hole position, two Hall sensors which are hot backups for each other are used for searching zero, then the final motor step number is calculated according to the current position and the target position, the calibration wheel motor is controlled to sequentially rotate by the final motor step number, the step number is corrected, and then rotation is stopped; and the satellite-borne software records the current position of the calibration wheel and downloads related telemetry data. The position conversion accuracy of the calibration wheel can be guaranteed, and meanwhile the service life of the calibration wheel motor is shortened.

    本发明涉及一种在轨高可靠的定标轮电机控制方法及星载软件,属于卫星平台及星载软件技术领域,解决遥感仪器任务周期内每次定标轮都能够可靠、准确地更换到目标位置且满足定标轮电机寿命要求的问题。其中控制方法具体包括以下步骤:对两个霍尔传感器和定标轮上各孔位、磁钢的位置进行量化;获取定标轮的目标位置及修正步数;若定标轮的当前位置未知或目标位置为定位孔位,则利用互为热备份的两个霍尔传感器寻零,再根据当前位置和目标位置计算最终的电机步数,控制定标轮电机依次转动最终的电机步数、修正步数后停止转动,星载软件记录定标轮的当前位置并下行相关遥测数据。本发明能够保证定标轮位置转换的准确性,同时节省定标轮电机的寿命。
