DIADEME 2, 2680
Orbit data source: Space-Track
DIADEME 2, 2680 is a payload satellite owned by CNES (FR) in LEO that was launched on Wed, 15 Feb 1967 UTC via a DIAMANT A launch vehicle from the Hamma Guira Space Track Range (HGSTR). Payload-class satellites include a variety of spacecraft equipped with specific instruments for various scientific and technological missions. These include communications satellites like Starlink; space stations such as the ISS; scientific satellites like the Hubble; Earth observation satellites from companies like Planet Labs, Umbra, and HawkEye 360; GPS; miniature CubeSats for education and research; and military/defense satellites.
