Horus The Lawrence Livermore National Laboratory Horus CubeSat picosatellite is a second generation miniature satellite based on the Colony II CubeSat Bus developed by Boeing for the National Reconnaissance Office (NRO). This mission is a pathfinder to assess performances of the Space-based Telescopes for Actionable Refinement of Ephemeris (STARE) concept. The STARE concept is a constellation of low cost nano-satellites in low-earth orbit dedicated to the observation of space debris in conjunction with a ground-based infrastructure for maintenance, coordination and data processing. Each nano-satellite in the constellation is capable of recording an optical image of space objects (debris or assets) at various range and relative velocities as scheduled by the ground infrastructure based on their closest approach distance (typically less than 1000m). The ground infrastructure processes the data received from multiple observations of the objects and reduces the positional uncertainty on the probability of collision to a level typically less than 100m, warranting taking actions such as moving assets. The Horus CubeSat intends to demonstrate the space segment performances (imaging sensor performances) of this concept as well as the performances of the post-processing of the data.
