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 Bolshoi-Planck simulation, with the same resolution as Bolshoi, was run in 2013 on the Pleiades supercomputer using the Planck satellite team's cosmological parameters released in March 2013. The Bolshoi-Planck simulation is currently being analyzed in preparation for publication and distribution of its results in 2014.
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.
