Study on spacecraft motion compensation technology for Chinese geostationary meteorological satellite remote sensing image

摘要

Because the satellite comes under influences from all kinds of disturbance and some of them can not be absorbed by flywheel control system during the circulation, attitude of satellite is disturbed, which results in pixel excursion of the scan mirror image, and image quality is affected. It is necessary to be compensated. Spacecraft motion compensation means that the influences of attitude disturbance are eliminated through producing scan mirror motion control compensation signal according to compensation arithmetic. It can be realized by using real-time compensation method and model predictor method. This paper studies real-time spacecraft motion compensation method. The valid arithmetic of spacecraft motion compensation and practicable technology project are proved through simulation. The research provides theoretical principles and practicable references to develop the new generation Chinese geostationary meteorological satellite.
