Abstract: The Advanced Terrain Tracking Altimeter (ATTA) Instrument is the new generation altimeter for the Earth Observation Preparatory Program (EOPP) of the European Space Agency (ESA). It is designed as a multimode adaptive instrument able to ensure full coverage of the Earth's surface, including land regions.

Both these corrections will be performed by the instrument itself, without the need of any add...
