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.
From the available GOCE data set composed of: GOCE level 1b dataset for orbit and attitude precise determination (GPS and Quaternion data) and special data set; TIRA radar observations (range, range- rate, azimuth, and elevation measurements), GOCE satellite 3D model and thermodynamic features and GOCE TLE data along the re-entry phase, three interrelated tasks are undertaken.
