Using cold atom interferometry (CAI) accelerometers in the next generation of satellite gravimetry missions can provide long-term stability and precise measurements of the non-gravitational forces acting on the satellites. This allows for a reduction of systematic effects in current GRACE-FO gravity field solutions. In this project, we first aim to investigate the hybridization of quantum CAI-based and classical accelerometers for a GRACE-like mission and we discusse the performance improvement through dedicated simulations. Then we investigate different orbital configurations and mission concepts to find the optimal setting for future satellite gravimetry missions.
