Description
This image shows the MéO (Métrologie Optique) observatory, a Satellite and Lunar Laser Ranging (SLR) dedicated telescope of the Observatoire de la Côte d'Azur (France), located at Plateau de Calern.
The telescope has a primary mirror of 1.54m with a focal length of 31m and uses an alt/azimuth mount with a fast motorization of 5 deg/s, allowing the tracking of satellites from low earth up to geostationary orbits and even on interplanetary missions. It is also used to measure the distance to the Moon to a precision of a few millimeters, by bouncing the laser off reflectors which were left behind by the American Apollo missions and on the Soviet Lunokhod1 rover in the 1970ies.
