The space environment is a set of surrounding composed of energetic particle radiation, micrometeoroids and space debris. The quantity of each element is defined by external physical world for a given launch time, altitude and duration of a specific mission. Proper evaluation is the key to verify best performance, problem avoidance and survivability of a system in space environment. In this work, the space environment analysis and evaluation for RASAT is reported with an emphasis on radiation analysis as being the most significant source of space product failures. For 2 mm aluminium shielding thickness, the forecasted value of total ionizing dose (TID) is 1.89 × 104 rads (Si) and non-ionizing displacement damage dose (DDD) is 5.42 × 107 MeV/g(Si) for 5-year mission lifetime of RASAT. We estimate 0.0005 m-2 flux of 1 mgr space debris for 5-year. Based on the analysis and evaluation results it is determined that RASAT components should not be less than ~20 krad.
