Deep Space Station 43 'Ballima'
..This antenna was originally constructed by Collins Radio between 1969 and 1972 as a 64 metre antenna. The antenna was upgraded in 1987 to 70 metres in diameter for the Voyager encounter with Neptune. The height of the antenna is 70 metres, similar to that of a 20 story building. The footings for the antenna are buried 10.1 metres underground for stability.
..Currently, this antenna is the largest steerable parabolic antenna in the Southern Hemisphere.
..The antenna is an Azimuth-Elevation configuration. The moving part of the antenna weighs approximately 3000 tonnes.
..The rotating structure (azimuth) moves on a hydrostatic bearing, comprising a film of oil 0.1 mm thick, which allows the massive structure to move smoothly and precisely. This bearing is basically a circular steel runner upon which three huge pads (weighing 7 tonnes each) rest. These pads have oil forced through them to lift them off the runner so that they 'float' on the oil. This provides a virtually frictionless bearing.
..Elevation is determined by a bullgear system with 22 segments 25.3 metres in diameter.
..The pointing accuracy of this antenna is 0.005 degrees which allows accurate communication with spacecraft millions of kilometers away. The antenna can receive signals at L band, S band, X band and K band and transmit at S band and X band.
..The dish has 1,272 panels constructed from aluminum with a total surface area of 4,180 square metres.
..The antenna can track in winds of up to 64 kilometers per hour and has a maximum survivable wind speed of 160 kilometers per hour.
