In conclusion, AIUB200a represents an alternative solution for the lunar gravity field from GRAIL data obtained using an independent software. Although convenient for the initialization of GRAIL data processing, the use of the dynamic GNI1B positions is not entirely satisfactory. The ongoing implementation of DSN Doppler data processing into the Bernese GNSS Software will allow us to contribute a fully independent solution. Moreover, to further improve our gravity field models, we intend to address the explicit modeling of direct and indirect solar radiation pressure and possibly other non-gravitational forces. Furthermore, the addition of the data at lower orbital altitude from the extended mission phase will strengthen our solutions.
