No. 1 Radar Surveillance Unit (1RSU) is the Royal Australian Air Force unit responsible for operating the Jindalee Operational Radar Network (JORN). While 1RSU's headquarters are located at RAAF Base Edinburgh the unit also has personnel stationed at the JORN sites near Longreach in Queensland, Alice Springs in the Northern Territory and Laverton in Western Australia.
1RSU was established on 1 July 1992 to operate the initial JORN site at Alice Springs and moved to RAAF Base Edinburgh in 1999. The sites at Longreach and Laverton were commissioned in mid-2003. In addition to the JORN sites, 1RSU operates the JORN Coordination Centre at RAAF Base Edinburgh which is responsible for providing JORN data to the system's 'customers', which include the Australian Strategic Theatre Joint Intelligence Centre and Northern Command.
