US Patent:

52048187, Apr 20, 1993

Filed:

May 7, 1992

Appl. No.:

7/883229

Inventors:

Peter B. Landecker - Manhattan Beach CA
Richard C. Savage - Franktown CO

Assignee:

The United States of America as represented by the Secretary of the Air
Force - Washington DC

International Classification:

B64G 136

US Classification:

364459

Abstract:

A surveying satellite apparatus having an on-board microprocessor to process sensor-provided data from planetary and/or celestial reference scene. The sensor data is compared with the on-board spacecraft database to determine if any misorientation or translation error is present. The spacecraft attitude and ephemeris solutions are autonomously updated to reflect the realtime alignment.

Abstract:

An imaging system is attached to a satellite, the imaging system includes a transmitting segment which transmits a field of view of photonic radiation to a focal plane array imager. Displacements such as jitter and drift are capable of being applied to the imaging system, which can result in apparent movement of said field of view applied to the focal plane array imager. A stabilizing segment limits the apparent movement of the field of view detected by said focal plane array imager in two orthogonal sensed translational directions, and about a sensed rotary direction.
