The Jindalee Operational Radar Network (JORN) is an over-the-horizon radar (OHR) network operated by the Royal Australian Air Force (RAAF) that can monitor air and sea movements across 37,000 square kilometres (14,000 sq mi).^{[citation needed]} It has a normal operating range of 1,000–3,000 kilometres (620–1,860 mi).^[1] The network is used in the defence of Australia, and can also monitor maritime operations, wave heights and wind directions.

JORN's main ground stations comprise a control centre, known as the JORN Coordination Centre (JCC), at RAAF Base Edinburgh in South Australia and three transmission stations: Radar 1 near Longreach, Queensland, Radar 2 near Laverton, Western Australia and Radar 3 near Alice Springs, Northern Territory.^[2]
