Abstract
Well-known orbital debris environmental models MASTER and ORDEM built by NASA and ESA respectively have big discrepancy in their debris flux models below the micro debris size scale. This paper addresses how to evaluate the confidence of MASTER and ORDEM by using debris detection rate acquired by in-situ debris observation on earth orbits. This paper suggests that ram direction is suited for the micro debris measurement to evaluate the confidence of MASTER and ORDEM. The proposed evaluation method expects one can judge the flux models of MASTER and ORDEM by 1-sigma degree of confidence in nearly every situation.
