This document summarizes the methods and results of the radiometric calibration update applied to 38 Dove satellites on the​ 30th of March, 2017. The satellites were part of Flock 2p, a group of 12 satellites in Sun-synchronous (SSO) orbit and Flock 2e, a group of 26 satellites in International Space Station (ISS) orbit. Flock 2p was deployed in June, 2016 and Flock 2e was deployed in 3 separate groups from the International Space Station between May and September, 2016. This was the first update to the radiometric calibration of Planet Dove satellites using on-orbit methods and the update is retroactive to the analytic product catalog of these satellites. The update corrects for systematic bias in the per-band calibration and minimizes relative differences between Dove satellites. The radiometric uncertainty across all satellites in these groups is measured at 5-6% at 1-sigma after this calibration update.
