In the final phase of the USERS mission, the REV capsule with orbital experiment samples made a reentry flight from the low earth orbit and was successfully recovered on the sea. Because the USERS REV capsule is the first domestic reentry capsule developed in pure domestic technologies, the post flight analysis of the recovered heat shield is significant not only for the design validation but also for the future application. Moreover, the READ experiment was carried out by the on-board unit for the diagnostics of the flight environment. This paper presents a reproduction of the reentry flight trajectory and the flight environment based on the comparison between the flight data and numerical simulations for the sake of the post flight analysis of the thermal protection system, READ experiment, and other systems' design validation.
