Abstract
A method of determining position of an object using an imaging device includes imaging a celestial object using an imaging device. A difference between an expected position of the celestial object and an actual position of the celestial object is determined. Pointing of the imaging device is in-flight calibrated to improve position determining by nulling the difference between the expected position of the celestial object and the actual position of the celestial object. Systems for determining position of an object relative to a vehicle are also described.
