ESA is currently preparing Envisat, Europe's largest remote-sensing satellite to date, for launch. Its payload includes an advanced instrument complement designed to guarantee the continuity of observation started by its predecessors and to meet the global Earth-monitoring requirement on a longer time scale. In particular, the altimetry from Envisat will benefit from the improved performance of a dual frequency Radar Altimeter (RA-2) working in synergy with the Microwave Radiometer (MWR) and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) instruments. The ground processing products that will be available in near-real-time will be as comprehensive as the off-line products, differing only in terms of the availability and quality of the auxiliary data.
