Abstract
Planet currently operates a constellation of over a hundred satellites that collect a current image of the Earth each day. These satellites were launched over several years and cover several evolutions in design. This presentation will describe the process of updating the calibration of all the Planet Dove satellites using the archive of data in preparation for a new product release to customers in the summer of 2021. The on-orbit calibration methodology will be described combining simultaneous crossovers and lunar observations as well as results using the updated calibration. Research of per-scene harmonisation with a Sentinel-2 reference will also be shown demonstrating improvements in interoperability across different satellite generations.
