Abstract :
WITTEX consists of three (or more) TOPEX-class radar altimeters on individual satellites in the same orbit plane. Earth rotation separates their respective sub-satellite tracks. Data from such an array can support measurement of both components of the surface gradient, and offers a variety of beneficial solutions to the time/space sampling trade-off. A similar configuration (WITTEX-Wide) when wrapped around a wide-swath altimeter can mitigate off-nadir height errors, thus reducing wide-swath measurement latency from twenty days to near-real time
