HartRAO also runs a Space Geodesy programme using VLBI, Satellite laser ranging and the Global Positioning System.
The LLR system will use a 100 mJ, 20 Hz, 80 ps pulse length laser to range to corner cube reflector arrays on the Moon.
The XDM dish design was first used in KAT-7, a seven-dish engineering testbed and science instrument in the Meerkat National Park in Carnarvon, Northern Cape.
