The Ice, Cloud, and land Elevation Satellite will measure ice-sheet topography using the Geoscience Laser Altimetry System. A simulation was conducted to determine the maneuvers required to maintain the ground track, at all latitudes, within 800-m of a repeating reference. Longitude targeting was used to maintain the ground track at the equator. A latitude targeting scheme has been developed to maintain the ground track at high latitudes. A maneuver simulation for the entire 3-year mission of ICES at resulted in 156 tangential maneuvers totaling 17.861 m/s of DELTAV and 7 normal maneuvers, totaling 11.42 m/s of DELTAV.
