FAIR USE used to9 inform. = “The Jindalee Operational Radar Network (JORN) consists of two OTHR(over the horizon radar), one near Longreach, Qld. and the other near Laverton, WA, jointly operated from the JORN Coordination Centre (JCC) at RAAF Base Edinburgh, SA by No 1 Radar Surveillance Unit. The radars are an advanced development of the Australian designed Jindalee radar at Alice Springs which is in operational use as well as being a research and development facility used by DSTO for ongoing OTHR improvement. JORN radars are capable of all weather detection of air and surface targets inside an arc of up to 3,000 km range extending from Geraldton in the west around to Cairns in the east. JORN makes a crucial contribution to broad area surveillance of Australia’s strategically important northern approaches. http://upload.wikimedia.org/wikipedia/en/8/88/Scanrange.jpg Australian HAARP?” ….25 1 2010…b.
