E-LORAN

[sarabande]

some concerns are being expressed by risk colleagues over the need to have access to a reversionary navigation system (apart from chart and pencil) because of the vulnerability of satellite-originating GPS. This relates to management of such objects as trucks and similar high-value fast moving goods.

I used the old Loran many years ago so am familiar with the concepts, but has anyone had recent experience of the new version(s) please ?


(And indications of cost of equipment would be particularly useful.)


TIA

Don't know any user who is actually using the eLoran system.

is there any commercially available receiver equipment ??

Some use the Russian Chayka satellite system as an alternative to the US DOD GPS system but it never really caught on in Europe.

In this article published earlier in the week Trinity House are pushing eloran.

Exactly what vulnerabilities are they concerned about? Are their concerns realistic or the result of consultants looking for justification for their fee?

The satelites may catch fire and fall from the skies! Or an alien vessel may hit one. Or the Sun might go out (although I hear the Sun will be 7 days a week from now on) and they will lose power. Or a very very thick layer of cloud may prevent the signal getting through.

Of course in reality, the ground stations are more likely to get damaged because down here we have weather, poorly trained engineers, teenagers with cider etc etc.

No need to worry. The European Union have it all in hand.

' if events go Mr Tajani's way the 24 satellites could be in orbit by 2015/16' from here http://www.bbc.co.uk/news/science-environment-13871198

'Europe is moving closer to the launch of its satellite navigation system Galileo.'http://www.aatl.net/publications/galileo.htm Unfortunately that article is dated 2001.

However, the independent think tank Open Europe has estimated "that the cost to European taxpayers of developing and running the EU’s Galileo satellite project for 20 years has gone from €2.6 billion under the original estimates (from 2000) – to a staggering €22.2 billion, according to recently leaked information" From the mid term review http://www.th-eu-nit.com/index.php/...n-satellite-navigation-programmes-ini20092226
