The Apache Point Lunar Laser Ranging Station utilizes the Astrophysical Research Consortium 3.5-meter telescope at the Apache Point Observatory in Sunspot, New Mexico. The large collecting area of the Apache Point 3.5 m diameter telescope, good atmospheric conditions at the site, and the efficient avalanche photodiode arrays used by the station result in a high-detection rate (even multiple detections per laser pulse) leading to millimeter-level range precision.
