JAXA has been developing Next Generation Star Tracker. Star Tracker (STT) is an attitude sensor, which consists of hood, lenses, CCD, and some electric circuits. In acquisition mode, images of the stars detected by CCD are compared with a star catalogue to determine its absolute orientation of a spacecraft without a-priori attitude information. STT can be more accurate attitude sensor than earth sensor plus sun sensor system. Advanced Land Observation Satellite (ALOS) mounts STT of large size to fulfill its high attitude accuracy requirement. On the other hand, an autonomous STT has been developed whose size, power and mass is smaller than ALOS/STT. It is named Next Generation Star Tracker.
