The success of the Cosmic Radiation Environment and Dosimetry (CREDO) experiment carried on-board the UoSAT-3 micro-satellite (launched in 1990) has lead to the development of a new instrument called the Cosmic-Ray Experiment (CRE) which has flown on-board the KITSAT-1 and PoSAT-1 micro-satellites, launched in 1992 and 1993 respectively. The results from both CRE instruments show excellent agreement with those of CREDO for the galactic cosmic-ray environment. However, there are some differences in the CRE and CREDO response to the trapped proton environment of the South Atlantic Anomaly which can be explained by the differences in the detector response time. The fit between the flight results and predictions from the standard models is generally good, but some differences are noted. The CRE and CREDO instruments should provide continuous coverage of the near-Earth radiation environment across a complete solar cycle. This is important in view of the dynamic nature of the radiation environment - as amply demonstrated by the results from the CRRES spacecraft.
