Since 2003 the European Space Agency (ESA) has promoted studies for the preparation of a “Next Generation Gravity Mission” with the objective of measuring the temporal variations of the Earth gravity field over a long time span with unprecedented spatial and temporal resolutions. This paper presents an overview of the main results of the “NGGM: AOCS Solutions and Technologies” study carried out for ESA by Thales Alenia Space Italia (TAS-I) in cooperation with Politecnico di Torino (I): the Study focuses in particular on the design of the control system, in order to identify the critical technologies (at hardware and software definition level) and to assess their feasibility and the design drivers.
