A New Collapsing Technique for Star Identification Using Sensors with Nonsimultaneous Acquisition Times

Abstract

A new stellar image mapping technique based on a state transition matrix form of solution for the rotational motion of a satellite is described. This technique allows star hits observed by an on-board sensor over a period of time to be effectively collapsed to an instantaneous photograph. When good rate gyro samples of the angular velocity are available, this collapsing is rigorous.
