The Satellite Tracking station of the French CNES

Only shortly after the decision had been made in favour of the location of Stephani, a delegation of French scientists of the French Centre National d' Etudes Spatiales (CNES) visited Greece in search for a suitable location for the installation of a satellite tracking station. France had just become the 3rd nation next to the USA and the USSR to claim space power status by launching satellites into orbit. Two satellite tracking stations were already in place at the Observatoire de Haute-Provence in France and at Colomb-Bechar in Algeria, but in order to achieve more accurate tracking, a third station situated in the Eastern Mediterranean was needed. The location of the Stephanion Observatory in Greece was considered ideal for that purpose.

The satellite tracking station started operation in October 1966 - a couple of months prior to the German reflector- under the direction of Pierre Foussier Equipped with one Doppler tracking and one Laser ranging station, the station held track of three French satellites: D1A Diapason, D1C-Diademe1 and D1-D Diademe2, that were subsequently launched during 1966-1967 from the French base at Hammaguir, Algeria with the Diamant rocket, the first launch system not built by either the USA or the USSR that was later to become the predecessor of all European launcher projects. The satellites were designed for experimental geodetic studies using Doppler effect and laser telemetry techniques. The Diademes were also destined for the installation of a navigational system by satellite.

The station was in regular operation until the End of August 1967, when it was transferred back to France after operation of the station at Colomb-Bechar came to and end when the treaty between the government of France and Algeria was discontinued. Stephanion's Doppler system was transported to the Space Center at Bretigny-sur-Orge in France and the Laser system to the Guiana Space Centre (CSG) in Kourou, French Guiana.
