Abstract
Imaging payload sensor calibrations are typically performed under laboratory conditions prior to launch and then routinely while on-orbit by using ground or astronomical based reference sources. With a trend towards autonomous operations, many machine-learning algorithms would benefit from having on-demand calibration across multiple detectors to better enable capabilities, for example using long wave infrared observations to identify and distinguish clouds from snow and ice. This subsequently would allow satellites to identify clouds confidently onboard, and downlink well defined clear images.
Presented are two technologies that provide a method for the direct on-orbit calibration of optical and thermal cameras used in small satellite payloads, thus moving technology usually reserved for large satellites into smaller and more nimble structures. End users include a broad range of stakeholders in scientific, commercial, and military sectors. Additionally, this development could be applied to laboratory, terrestrial, or marine instruments.
