As computing technologies improve, spacecraft sensors continue to increase in fidelity and resolution, their dataset sizes and data rates increasing concurrently. This increase in data saturates the capabilities of spacecraft-to-ground communications and necessitates the use of powerful onboard computers to process data as it is collected. The pursuit of onboard, autonomous sensor processing while remaining within the power and memory restrictions of embedded computing becomes vital to prevent the saturation of data downlink capabilities. This paper presents a new ISS research experiment to study and evaluate novel technologies in sensors, computers, and intelligent applications for SmallSat-based sensing with autonomous data processing. Configurable and Autonomous Sensor Processing Research (CASPR) is being developed to evaluate autonomous, onboard processing strategies on novel sensors and is set to be installed on the ISS as part of the DoD/NASA Space Test Program –Houston 7(STP-H7) mission. CASPR features a flight-qualified CSP space computer as central node and two flight-ready SSP space computers for apps execution, both from SHREC, a telescopic, multispectral imager from Satlantis Inc., an event-driven neuromorphic vision sensor, an AMD GPU subsystem, and Intel Optane phase-change memory. CASPR is a highly versatile ISS experiment meant to explore many facets of autonomous sensor processing in space. |
