After the success of GEOSAT’s Exact Repeat Mission (ERM), in February 1998 the U.S. Navy launched the mini-satellite GEOSAT Follow-On (GFO). The mission had the same mission objectives as GEOSAT’s ERM, as well as its orbit configuration and ground track (for further details please refer to GEOSAT page).
