The Jindalee Operational Radar Network Communications and the Operational Concept
Nicholson, P1; Cameron, A2

Abstract: The operational concept of the Jindalee over-the-horizon operational radar network (JORN) is the centralised control and co-ordination of remote sensors. The radar sites are in Laverton, WA and Longreach, Queensland, while the co-ordination centre is situated in Adelaide, South Australia. An extensive communications network is needed to control the radars and their associated frequency management systems, transfer partly processed data for final analysis at the co-ordination centre, and pass track information to the command support systems of the Australian Defence Force and other users. The principle of operation, configuration and concept of the Jindalee project are briefly outlined to provide the context of the communications requirement. The communications infrastructure to support this operational concept is then described together with the main factors which have influenced the design of JORN communications.

The following are some notes from an 'insider', and are added as a source of info to follow up on, as we did to present the JORN information.

"Yes it may have had something to do with HAARP. However the Australian end of HAARP is situated at Laverton Western Australia. You can see it on Google Earth. Just type in ‘Laverton Western Australia’ in the search box. It is out in the middle of nowhere, far to the south east of North West Cape. But they may be associated. Take a look at it, and check out some of the odd features, including the unusually large airstrip to the north east of the small town. Apparently HAARP requires these so called focal points to operate globally. I don’t know if there is any truth in it, but I was told in the USA that the original purpose of HAARP was to create a powerful force field earth defence system. The disruption of the climatic system could be a secondary result of such machinations."

"I just checked with an old friend of mine (now 86), who was involved in the earlier Jindalee experiments at Salisbury Weapons Research South Australia. He said that the central part of the system is now definitely located outside Longreach QL, as its geographic location is considered ideal, and it’s construction turned Longreach into a boom town. I remember hearing talk of that some years ago. And yes it was later coupled to HAARP via Laverton WA. Apparently, and this is what he believes, it utilises the HAARP electromagnetic field to extend its range far into northern China and most other parts of Asia. Perhaps worldwide, who knows? Incidentally it was sold off to American interests for US$400,000,000 after the Australian tax payer had invested almost two billion! Now that was a good deal if ever there was one."

"Yes that’s it. It is the most important part of the system" (In reference to the image shown on this page)

I will look into the Chinese side of things. The Jindalee system is situated outside “Longreach Queensland”. It was built at Australian taxpayer’s expense and sold to America for half price. It is over horizon radar, and can reach as far as Northern China. As soon as it worked America took it over. Such is life in a vassal state.

"I recall NCR was involved too. Whatever, it has cost billions, and I understand the Chinese and Russians have developed counter measures." (In reference to RayTec - See Below)

Australia’s Jindalee Radar Profiled

January 9, 2006

Australia’s Jindalee radar system, capable of “seeing” over the horizon, was recently profiled in The Australian. While standard radar sends a signal along line of sight until it bounces off its target (and therefore cannot “see” beyond the horizon), Jindalee bounces signals off the ionosphere, which lies above the stratosphere and extends about 1,000 kilometers above the surface of the Earth. The signal then bounces down onto its target, allowing Jindalee to detect threats over the horizon. In this manner, Jindalee, officially known as the Jindalee Operational Radar Network (JORN), will significantly increase the time during which the U.S. and its allies can intercept incoming ballistic missiles. The Australian notes that Jindalee will be part of a larger electronic network, including spy satellites and Aegis destroyers, able to pick up the launch of a missile and determine its course and destination. Australia plans to buy three air warfare destroyers, to be equipped with the Aegis BMD system.

In July 2004, the United States and Australia signed a memorandum of understanding pledging cooperation on missile defense for the next twenty five years.  (Article, Link)
