PRETTY
PRETTY stands for Passive REflectometry and DosimetrY and represents a 3U CubeSat hosting two scientific payloads. The main payload is a passive reflectometer, which uses already available GPS/GALILEO signals to perform Earth observing tasks. The secondary payload is a dosimeter and detects radiation levels on board the spacecraft to allow insights and gain information on the sun activity and space weather.
More information on the mission and the spacecraft can be found in the menu on the right, as well as on Twitter:
The PRETTY mission was successfully completed at the end of 2024 following a post-flight review by ESA. Due to the satellite’s flawless technical performance, a request for mission extension was submitted and granted. In 2025, PRETTY was incorporated into the OPS-SAT initiative and integrated into the OPS-SAT Space Lab under the new name OPS-SAT PRETTY (funded by GSTP).
