ABSTRACT:
A star tracker 10 of an attitude control system 8 on board a spacecraft 9 is positioned so that the tracker's line-of-sight vector 12 intersects the origin of the reference axis but is askew from any reference axis of the spacecraft. The attitude control system transforms the dam from a star tracker reference coordinate system to a spacecraft reference coordinate system so as to allow control of the attitude of the spacecraft without modification of existing equipment.
