PRETTY (Passive REflecTomeTry and dosimetrY) is a CubeSat mission by the European Space Agency (ESA).[1][2] The primary payload of the satellite is a passive reflectometer for GNSS reflectometry measuring sea state, sea ice, and ocean currents by receiving Galileo and GPS signals reflected from Earth surface.[3] The secondary payload is a radiation monitor.[4] The satellite was launched in October 2023 on a Vega rocket.[5][6][7]
