GREENBELT, MD (July 13th, 2021) – Orbit Logic has been awarded a Phase I Small Business Technology Transfer (STTR) contract from NASA to develop the On-board Swarm Control for Autonomy and Responsiveness (OSCAR) solution – an onboard software solution employing autonomous collaborative planning in support of heterogeneous spacecraft swarms. OSCAR is being developed in partnership with the Autonomous Vehicle Systems (AVS) lab at the University of Colorado Boulder.
OSCAR will leverage Orbit Logic’s Autonomous Planning System (APS) onboard planning/response framework and the AVS Lab’s satellite formation flying simulation capability using the Basilisk framework [1] to develop a capability that will allow a swarm of planetary-orbiting satellites to dynamically adapt their configuration to accommodate varying mission needs. OSCAR will determine, plan and orchestrate the relative movement of each swarm element to achieve mission-enabling formations. “Convoys” or “string-of-pearls” (subfigure A) will allow events detected by leading satellites to trigger follow-up responses by following satellites. Offset, time-varying double echelons (subfigure B) will provide coverage of large swaths of ground area. Single (subfigure C) or multiple (subfigure D) synthetic apertures will enable coordinated collection of space-resident or planetary surface data by selected subgroups of asset elements.
Figure 1: OSCAR would enable spacecraft to dynamically transition between different formations.
An instance of APS would operate onboard each swarm asset to provide asset level resource planning and independence – enabling autonomous cooperation between assets over intermittently available communication links. Onboard, OSCAR would determine times at which new formations would be necessary (e.g., in preparation for a specific type of science gathering or in response to an unanticipated dynamic event), and then plan and orchestrate the movement of individual satellites between these configurations without the assistance of mission control. These adaptive strategies would be useful on Mars, to seek and track dust devils, and on Enceladus or Europa, to identify and then closely monitor unpredicted geyser eruptions.
APS is a powerful technology that can be leveraged for autonomous planning in any domain. The breadth of its applications proves its flexibility; beyond robotic Lunar exploration, Orbit Logic has utilized APS for the autonomous operation of heterogeneous constellations of Low Earth Orbit (LEO) satellites [1] with DARPA and AFRL, heterogeneous teams of unmanned underwater/surface/aerial vehicles (UUVs/USVs/UAVs) with the Navy [2], heterogeneous swarms of rovers, satellites, and atmospheric vehicles for robotic Mars exploration [3], and heterogeneous robotic swarms with astronauts-in-the-loop for Lunar exploration [4] with NASA.
