In mid-1968, at the facility KIP-10 or NIP-10 (КИП-10 or НИП-10) in the secret village Shkolnoye (:ru:Школьное (Крым) - closed town Simferopol-28), near Simferopol, a lunodrom (лунодром - Moondrome) was built. It covered an area of one hectare (120 meters by 70 meters) and was very similar to some parts of the lunar surface. It was constructed using more than 3,000 cubic meters of soil, and included 54 craters up to 16 m in diameter and around about 160 rocks of various sizes. The whole area was surrounded with bricks, painted in gray and black. It was used to analyze problems with the Lunokhod chassis and cosmonaut's skill to control one. Closed town Simferopol-28 contained the most significant tracking facility in the Soviet Union, having the largest number of antennas, the largest area, and the most personnel of any of the Soviet tracking facilities. The facility was one of a network of ten facilities which contain earth satellite vehicle tracking equipment and provide command/control for Soviet near-space civil and military events. Additionally, this facility supported all lunar programmes of the Soviet Union, in association with the Evpatoria Deep Space Tracking Facility.
