It can acquire high-resolution data, especially in the steeply sloping coastal areas, where the radar altimeters flown on many other Earth observation satellites struggle to see important details.

Radar altimeters flown on missions previous to Cryosat have not had the resolution to do this as precisely as researchers would like, and have not flown far enough to the north to get a full view of the Arctic basin.
