The Pléiades system was designed under the French-Italian ORFEO Programme (Optical and Radar Federated Earth Observation) between 2001 and 2003. [2]The Pléiades programme was launched in October 2003 with CNES (the French space agency) as the overall system prime contractor and EADS Astrium as the prime contractor for the space segment.
Yet some authors argue that the controversy over the distance to the Pleiades discussed below is a red herring, since the cosmic distance ladder can (presently) rely on a suite of other nearby clusters where consensus exists regarding the distances as established by the Hipparcos satellite and independent means (e.g., the Hyades, the Coma ...

The Naval Ocean Surveillance System (NOSS) is a series of signals-intelligence satellites that have conducted electronic signals intelligence for the U.S. Navy since the early 1970s. [1] The first series of satellites were codenamed "White Cloud" or "PARCAE", while second- and third-generation satellites have used the codenames "Ranger" and ...
Astrosat-1000 is the largest option in EADS Astrium's Astrosat family of satellite buses. Astrosat-1000 provides the basic structure for building satellites between 800 and 1200 kg in mass. It is the satellite bus used for the Pléiades-HR series of satellites. [1] [2] [3]
The constellation Pleiades pays homage to the organization's past as a United States Army unit and the seven stars represent previous command structure and operational elements at each Wideband Satellite Operations Center. Ancient stories depict the Pleiades as a group of loved ones who left their way of life to ascend to the heavens, and the ...
Thuraya is the mobile satellite services subsidiary of Yahsat, a global satellite operator based in the United Arab Emirates, fully owned by Mubadala Investment Company. [ citation needed ] The geostationary nature of the service implies high round-trip times from satellite to Earth, leading to a noticeable lag being present during voice calls.
AstroBus-L: A platform suited for high-performance Earth observation satellites such as the Pleiades Twin satellites and the SPOT satellite system. Xpress: Low-cost synthetic aperture radar (SAR) satellite system particularly suitable for surveillance applications in a constellation concept.
