Abstract
An inertially aided optical sensing system including an optical sensor, for example a telescope, and an optical reference gyro (ORG). The ORG emits a beam of collimated light aligned with the gyro's angular momentum vector. This light beam is directed into the optical sensor, e.g. a telescope, to create a bright spot, or 'star', on the focal plane of the sensor. A closed loop control system adaptively controls the ORG, sensor or both in response to signals representative of the position of the beam incidence point in the focal plane in order to offset dynamic misalignments between an inertial reference system and the optical axis of the sensor arising from bending and internal frame deformations within the optical system.
