This product is the new generation of the star sensor based on the traditional technology of the single FOV star sensor. With the characteristics of the EU’s dual-redundant backup and supporting simultaneity operation of 1 to 3 Optical heads, the on orbit interference resistance and reliability of the star sensor can be ensured to a great extent. Compared with single FOV star sensor, ST-APS3-M-2 greatly promotes the precision of the optical axis direction, through the pipeline exposure, the data update rate can be promoted meanwhile, and multi-FOV star information can provide plenty of bright stars, hereby, the dynamic performance will be improved. It has been used for a high-orbit satellite, subsequent application in satellite spacecraft platform with high attitude accuracy requirements will come to reality.
