ICESAT-2 Satellite Orbit

ICESAT-2 is a satellite part of NASA's Earth Observing System with the goal to continue measuring and monitoring the impacts of the changing environment. The ICESAT-2 observatory contains a single instrument, an improved laser altimeter called ATLAS (Advanced Topographic Laser Altimeter System). ATLAS is designed to measure ice-sheet topography, sea ice freeboard, as well as cloud and atmospheric properties and global vegetation.
