Abstract :
The Cosmic Radiation Effects and Dosimetry (CREDO) system is discussed. In order to explore the environment in polar-platform orbit, it has been incorporated into the UOSAT-3 microsatellite, which was successfully launched into an orbit of altitude 806×797 km and inclination 98.7° during the Ariane launch of SPOT-2 in January 1990. Results on quiet-time operation, solar flare periods, and observations of the South Atlantic Anomaly are discussed. Flights on a number of future missions encompassing a variety of orbits are under consideration including a flight in geostationary transfer orbit on the DRA microsatellite STRV-1 in 1992
