Abstract. The Lunar Laser Ranging station at the Observatoire de la Côte d'Azur, France, permits to measure the Earth-Moon distance with millimetric precision. Applications in astronomy, lunar science, geodesy, and gravitation are summarised. Expected scientific results with millimetric Lunar Laser Ranging data are presented. A complete error budget is given, showing that the precision is mainly limited by the orientation and the size of the corner cube arrays placed on the Moon. The measurement accuracy is degraded by the bad knowledge of the air index. The time stability, computed from the lunar echoes, permits to extract the real precision of the EarthMoon distance and to optimise the integration time of the normal points.

“…As early as in 1970, some Earth-Moon distances have been obtained with a precision in the 25 cm range at the McDonald laser station (Texas). Four other retroreflector arrays have been placed during the following Apollo XIV and XV, and Lunakhod 1 and 2 missions Faller 1972); (Chang et al 1972); (Fournet 1972).…”
