In prior work, we have developed a visual approach for attitude propagation. By tracking the motion of stars in a camera\u2019s field of view, the rotation of the spacecraft can be found in three degrees of freedom. We refer to the approach as a stellar gyroscope. The proposed work builds on the prior success and findings to pursue a promising new topology. Essentially, we will miniaturize the sensor nodes and lenses to design a camera in the size range of modern smartphone cameras capable of star imaging while utilizing the stellar gyroscope algorithm\u2019s noise tolerance in post-processing. This will allow small spacecraft to incorporate up to one camera on each side if needed, with one centralized image processing subsystem.<\/p>\n<p><a href=\"http:\/\/104.131.50.231\/wp-content\/uploads\/2015\/03\/MSGC-Star-Imaging.png\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-331 aligncenter\" alt=\"MSGC Star Imaging\" src=\"http:\/\/104.131.50.231\/wp-content\/uploads\/2015\/03\/MSGC-Star-Imaging-300x144.png\" width=\"300\" height=\"144\" srcset=\"https:\/\/sar-lab.net\/wp-content\/uploads\/2015\/03\/MSGC-Star-Imaging-300x144.png 300w, https:\/\/sar-lab.net\/wp-content\/uploads\/2015\/03\/MSGC-Star-Imaging-768x369.png 768w, https:\/\/sar-lab.net\/wp-content\/uploads\/2015\/03\/MSGC-Star-Imaging.png 924w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We have received an award from the NASA Michigan Space Grant Consortium to develop a star imaging approach for CubeSats using an array of miniature cameras.
