RealTOR TechPort Info
NASA is continuously working to advance optical communications technologies to meet the demand for higher communications data rates by developing and testing low cost ground-based optical receivers for space-to-ground communications required for future space explorations systems such as Artemis and Lunar Gateway Programs. The Real Time Optical Receiver (RealTOR) Project’s goal is to provide a commercial-off-the-shell (COTS) portable, scalable, modular, low cost solution for optical communications ground photon counting receivers. The RealTOR system implements the Consultative Committee for Space Data Systems (CCSDS) Optical Communications High Photon Efficiency (HPE) standard, which will be used in future photon counting missions such as the Optical Artemis-2 Orion Communications (O2O) mission.
