    Towards More Efficient Use of Radar-Altimeter Data

    Twenty years ago, experimental altimeters on NASA's Skylab and Geos-3 were already demonstrating the potential of such instrumentation. This led in turn to the development and launch by NASA in July 1978 of the Seasat oceanographic satellite mission. Both Geos-3 and Seasat were very successful in their pioneering missions, but were limited somewhat by poor coverage in the case of Geos-3 and an abnormally short mission duration in Seasat's case.
