Abstract:
A miniaturized astrometric alignment sensor may detect stellar objects and targets from which both stellar and object tracking are performed. The sensor may search for one or more bright opens in an image captured by a camera of a space vehicle, and determine if the one or more bright objects is a genuine star or a secondary element. The sensor may also catalog entries of identified stars after three or more bright objects are determined to be genuine stars, and display the cataloged entries of the identified stars, wherein the cataloged entries comprises positional and velocity of the space vehicle in relation of the identified stars and a sensor body reference frame.
