The Navy's Geosat Follow-On (GFO) Mission, launched on February 10, 1998, is one in a series of scientific altimetric satellites which include Seasat, Geosat, ERS-1, and TOPEX/POSEIDON (T/P). Data derived from these missions has and will lead to vast improvements in our knowledge of ocean circulation, ice sheet topography, and climate change. In order to capture the maximum amount of information from the altimetric data, accurate altimeter calibrations are required for the civilian data set which NOAA will produce. NASA/Goddard Space Flight Center/Wallops Flight Facility (GSFC/WFF) has provided these products for the Geosat and T/P missions and will do the same for GFO.
