Abstract:
During this Instrument Incubator Program project, the ARCSTONE team will develop and build an ARCSTONE observing system that will demonstrate a new calibration and measurement technique for the purpose of calibration lunar spectral reflectance to high SI-traceable accuracy. This project will develop a flight-like ground demonstration unit, test and validate the radiometric performance and behavior of the integrated system. When deployed on-orbit, a future ARCSTONE observatory will be capable of establishing the Moon as on-orbit calibration source. Advancement of this technology will reduce the risk, cost, size, and performance/accuracy for past, present and future Earth observing sensors in low- and geo-stationary orbits (LEO and GEO, respectively). The ARCSTONE team will present the instrument design status and path forward for develoipment, building, calibration and testing.
