Abstract
With the increasing number of commercial satellite constellations launching, the need for calibration remains as relevant as ever. Some of these instruments are built with COTS optical components and, given the number and need for timely calibration, a flexible, dynamic, and streamlined approach is necessary for reproducibility, regression testing, adaptability, and high-quality image data. We present a use case for a commercial VNIR payload and demonstrate techniques and a storyboard of our experience. We ran a calibration campaign on a 100” focal length telescope assembled in a payload of approximate 50kg containing a commercial Bayer pattern camera of medium resolution (6600x4400 pixels). We performed nonuniformity correction (NUC), focus estimation, camera parameter settings, off-axis scatter measurements, and an assessment of a charge-coupled device (CCD) smear. It is understood that there is a level of risk accepted in the commercial enterprise. In our case, the first two satellites out of a constellation of approximately 100 satellites are intended for a proof-of-concept (POC) to facilitate a baseline of sensor performance and to provide a calibration template for the remaining satellites.
