Gravity Recovery and Interior Laboratory (GRAIL): Mapping the Lunar Interior from Crust to Core,unch on September 10, 2011, the twin GRAIL orbiters embarked on independent trajectories on a 3.5-month-long cruise to the Moon via the EL-1 Lagrange point. The spacecraft were inserted into polar orbits on December 31, 2011 and January 1, 2012. After a succession of 19 maneuvers the two orbiters se

The Lunar Gravity Ranging System for the Gravity Recovery and Interior Laboratory (GRAIL) Mission, at the Moon allows use of a single-frequency link and elimination of the accelerometer compared to the GRACE instrumentation. This paper describes the implementation, testing and performance of the instrument complement flown on the two GRAIL orbiters.
