Attitude motion compensation for imager on Fengyun-4 geostationary meteorological satellite

- An attitude motion compensation method for Chinese Fengyun-4 satellite is proposed.
- The method can counteract the line-of-sight deviation during attitude motion.
- The compensation is added to the instrument scanning control circuit and executed.
- An imaging test with the three-axis air-bearing physical simulator is proposed.

A compensation method is used in Chinese Fengyun-4 satellite to counteracting the line-of-sight influence by attitude motion during imaging. The method is acted on-board by adding the compensation amount to the instrument scanning control circuit. The mathematics simulation and the three-axis air-bearing test results show that the method works effectively.
