GGTS 1, 2

GGTS 1 [USAF]

GGTS (Gravity Gradient Test Satellite) were two experimental satellites to investigate gravity gradient stabilisation in geostationary orbits. They were each launched together with 7 IDCSP communication satellites. The GGTS satellites used the same bus as the IDCSP, but were battery powered.

GGTS 1 was successfully launched on a Titan-3C into near geosynchronous orbit, but the GGTS 2 mission failed due to a launch vehicle failure.
