The SmallSat Technology Partnerships (STP) Technology Exposition on May 24, 2021 will provide an opportunity to learn about advanced SmallSat technologies that could enable future missions or be accessed for commercialization. Stanford’s Space Rendezvous Laboratory (SLAB) will present three new navigation technologies for satellite formation-flying and swarms: Distributed Multi-GNSS Timing and Localization (DiGiTaL), Angles-Only Absolute and Relative Trajectory Measurement System (ARTMS), and Autonomous Nanosatellite Swarming Using Radio-Frequency and Optical Navigation (ANS). DiGiTaL provides nanosatellite swarms with unprecedented centimeter-level relative navigation accuracy using multi-GNSS at separations up to hundreds of kilometers in low Earth orbit. ARTMS enables satellite swarms to simultaneously estimate their own orbits and the orbits of nearby non-cooperative space objects using only inter-satellite bearing angle optical measurements in Earth’s and planetary orbits. ANS enables simultaneous navigation about and characterization of an asteroid using multiple autonomous swarming satellites equipped with optical cameras and radio-frequency cross-links.
