A modified Local Space Imaging System (LSIS) for near-sun detection
ABSTRACT: Aerophysics has developed the Local Space Imaging System (LSIS) to provide proximity detection for spacecraft. The LSIS sensor is a small, bolt-on unit that meets many of the requirements for this solicitation: the LSIS is small, low-power, semi-autonomous, and two LSIS units could cover the entire sky. However, like all passive EO detectors, LSIS has limitations when trying to detect unresolved objects close to or in front of the solar disk. Work proposed here will further improve LSIS performance by reducing its solar exclusion angle. Three design options will be evaluated to trade cost and complexity against performance improvement. BENEFIT: An all-sky version of LSIS could protect commercial spacecraft from collisions with orbital debris.
