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]
