Gravity field of the Moon from radio science tracking and
inter-satellite measurements of the GRAIL spacecraft (GRAZIL)

General information

The main goal of project 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; particular focus is on the separation of gravity field parameters from geophysical parameters. This goal shall be reached by dynamic precise orbit determination in combination with the analysis of the inter-satellite GRAIL measurements. The latter is based on expertise gained from gravity field recovery of the Earth (GRACE mission).
