The primary objective of GRAZIL is to derive a high-accurate gravity field model of the Moon from data collected by the Gravity Recovery And Interior Laboratory (GRAIL) mission. Additionally, geophysical parameters shall be estimated together with the gravity field in order to enhance our knowledge on the state and size of the lunar core. For this purpose, we make use of dynamic precise orbit determination in combination with a novel inference technique in lunar sciences. This approach is an adapted version of a method that has been developed and very successfully applied for terrestrial gravity field recovery (GRACE mission).
