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.

The present invention relates to a space-based instrument which provides continuous coronal electron temperature and velocity images, for a predetermined period of time, thereby improving the understanding of coronal evolution and how the solar wind and Coronal Mass Ejection transients evolve from the low solar atmosphere through the heliosphere for an entire solar rotation. Specifically, the present invention relates to using a 6U spherical occulter coronagraph CubeSat, and a relative navigational system (RNS) that controls the position of the spacecraft relative to the occulting sphere. The present invention innovatively deploys a free-flying spherical occulter, and after deployment, the actively controlled CubeSat will provide an inertial formation flying with the spherical occulter and Sun.
