The Near Earth Object Surveillance Satellite (NEOSSat)[8] is a Canadian microsatellite using a 15-cm aperture f/5.88 Maksutov telescope (similar to that on the MOST spacecraft), with 3-axis stabilisation giving a pointing stability of ~2 arcseconds in a ~100 second exposure. It is funded by the Canadian Space Agency (CSA) and Defence Research and Development Canada (DRDC),[1] and searches for interior-to-Earth-orbit (IEO) asteroids,[9][10] at between 45 and 55 degree solar elongation and +40 to -40 degrees ecliptic latitude.[3]
