The US Navy GFO (Geosat Follow On), is a 369 kg minisatellite based on the Techstar platform to carry on the mission of Geosat. It was launched on the 10th February 1998 on a Taurus-2210 from VAFB alongside two Orbcomm satellites, into a 789 × 881 km (779 × 790 km planned) 108 degree inclined orbit.
GFO was lifted into orbit during the mission ‘Taurus 2210 | GFO’, on board a Minotaur-C 2210 space rocket.
The launch took place on Feb. 10, 1998, 1:20 p.m. from Space Launch Complex 576E.
