Diego Garcia (-7.317,72.417) is an atoll located in the heart of the Indian Ocean,some 1,000 miles (1,600 kilometres) south of India's southern coast.Diego Garcia is the largest atoll by land area of the Chagos Archipelago.It is part of the British Indian Ocean Territory (BIOT),a British overseas territory.Since the depopulation of Diego Garcia in the years leading up to 1973,it has been used as a military base by the United States.Diego Garcia hosts one of three ground antennas (others are on Kwajalein and Ascension Island) that assist in the operation of the Global Positioning System (GPS) navigational system.The atoll is now covered in luxuriant tropical vegetation,with little sign left of the copra and coconut plantations that once covered it.The island is 37 miles (60 km) long,with a maximum elevation of 22 feet (7 m),and nearly encloses a lagoon some 12 miles long (19 km) and up to 5 miles (8 km) wide.Depths in the lagoon range from 65 to 98 feet (20-30 m),while numerous coral heads extend toward the surface and form hazards to navigation.Shallow reefs surround the island on the ocean side as well as within the lagoon.The channel and anchorage area are dredged,while the old turning basin can also be used if its depth is sufficient for the ship.
