Title:
SYSTEMS AND METHODS FOR ESTIMATING AN OBJECT'S ATTITUDE
Document Type and Number:
WIPO Patent Application WO/2012/044818
Kind Code:
A3
Abstract:
In general, in one embodiment, a starfield image as seen by an object is analyzed. Compressive samples are taken of the starfield image and, in the compressed domain, processed to remove noise. Stars in the starfield image are identified and used to determine an attitude of the object.
