CIRIS

Informationen über CIRIS

Technology demonstration mission of an imaging radiometer instrument for the 7 to 13 um infrared wavelength range. It will raise the technology readiness level of the new uncooled detector and carbon nanotube source from level 5 to 6, enabling future reduced cost missions to study the hydrologic cycle, characterization of ocean/atmosphere interactions vegetation and land use management. Uncooled imaging infrared (7.5 um to 13 um) radiometer designed for high radiometric performance from LEO on a Cubesat spacecraft. Design is based on a Ball aircraft-mounted instrument with modifications to improve radiometric uncertainty in the space environment. A high emissivity blackbody source coated with carbon nanotubes reduces error in on-board calibration. Will enable constellations of simple, inexpensive Cubesats to replace larger more complex instruments for multiple applications in scientific research and land use management.
