Star Sensor
SAST has developed many star sensors including CCD High precision Star Sensor (ST-CCD2-2B), APS High precision Star Sensor (ST-APS2-2) and ST-APS3-M-2 very high accuracy APS multi-star sensor Ⅱ( APS multi-star sensor Ⅱ), these star sensors adopt CCD detector and APS flat detector , have the characteristics of high precision, good dynamic performance and etc., can be used for GEO, MEO and LEO satellites and other spacecrafts.
