The SAC-C Satelite de Aplicaciones Cientificas C was developed by the Argentine space agency CONAE and built by the Argentine company INVAP. The 467 kg satellite carried a battery of earth observing instruments for Argentine forestry and agriculture studies. SAC-C also carried a NASA experiment which used the distortion of GPS signals observed near the horizon to derive atmospheric conditions.

Mass: 467 kg (1,029 lb).

SAC-C also carried a NASA experiment which used the distortion of GPS signals observed near the horizon to derive atmospheric conditions. The DPAF dual payload support structure, derived from Ariane's SPELDA, was ejected after deployment of the EO-1 satellite from the Delta stage to reveal SAC-C. After a further Delta burn SAC-C was ejected at 1955 GMT into a 687 x 707 km x 98.3 deg orbit.
