The project is dedicated to an in-depth study of the re-entry of ESA's Gravity Field and Steady-State Ocean Circulation Explorer (GOCE), for which a rich measurement dataset is available up to the very end of its decay phase.

The objective of ESA PREGO activity (ESA/ESOC contract 4000115173/15/F/MOS) is to improve the capacities on re-entry prediction thanks to a complete analysis of the outstanding data set related to the GOCE re-entry occurred in October/November 2013.

In the future, satellites will have to demonstrate compliance with debris mitigation requirements, covering re-entry or parking graveyard orbits and passivation. Nevertheless, during the mission, a failure could occur without any possibility to manoeuvre the satellite and achieving its compliance to the Space Debris Mitigation requirements. Therefore to anticipate the need to use ADR for deorbiting (or reorbiting) the satellite, it is interesting to evaluate the implication of adapting the satellites and launcher upper stage to support a future ADR mission.

The primary objective of the Benchmarking re-entry prediction uncertainties study is to fully exploit the informa- tion content of the GOCE observations and telemetry collected during its reentry phase for better understand- ing re-entry predictions in general and for GOCE in particular (ESA, 2015). Down to an altitude of 137 km, a rich data set of high-quality GPS, star tracker and also accelerometer observations were collected, be it that the latter were more and more saturated.
