Good old Carlo, as long as you have a reference to a pig, he is happy
The GNSS is an amazing system...Carlo got it wrong in a way. NAVSTAR was the airbourne equivalent of VLF/OMEGA. Both systems shared features where GNSS tracked and measured signals from satellites in known orbits, VLF/OMEGA tracked and measured signals from known ground stations.

And, speaking of interference-
From AvWeb...FCC to Suspend LightSquared Plans
From AvWeb...FCC to Suspend LightSquared Plans
The FCC will indefinitely suspend LightSquared's authority to carry terrestrial broadband signals on frequencies close to GPS frequencies after receiving a report that concludes the two systems cannot currently coexist.
Folks,
I noted, last week, that FAA has called tenders for equipment that can comfortably be installed in a small van, to hunt down whoever is deliberately jamming GPS/GBAS signals at several airports in US, where FAA have been conducting trials of such to the equivalent of ILS CAT II/III minima.
Meantime, said trials are suspended.
I am afraid that, as a great supported of the various uses of GPS, I am becoming progressively more aware that we shouldn't put all our eggs in one basket --- which seems to be altogether too close to what Airservices are planning.
And (quiet Ha Ha behind my hand) I notice Airservices are once again trialing approach procedures ------ that we first trialed, very successfully, in Brisbane soon after the new airport opens ----- how long ago??? 25+ years???
You certainly can't accuse Airservices of rushing new technology into operation ---- can you????
Tootle pip!!

Hope I am posting in right area.. Newbie here...
My father flew out of HFD from mid 1960's to later 70's, passed away in mid 2000's.. In cleaning out we have come across some older stuff that I thought I might try to sell.. Is this the right place to try to sell them? I do not want to do anything incorrectly, so I thought I would ask first. Thanks so much!

Hmmm... well, baswell, i dont actualy see much of any thread relavence to your comments. Offering up the unconnected dramatic "THE RISK OF TERRORISM" graphic seems a bit piontless.
To date there has been very little in the way of terrorists using bombed up GPS guided UAV's so how do you know what the actual impact will be on the general populance ? I'm thinkin once them terrorists start using GPS guided UAV bombs with the ability to hit within one cubic metre of air space they will probably be a bit selective of the targets - probably be political or business leaders.
"Last I heard, we still have airliners, rental trucks, petrol and fertiliser"
baswell, if you had been reading the many threads on this subject yer woulda seen the main senario i have been presenting is of small GPS guided UAV bombs launched from outside Australia's territorial boundry. It is very hard if not imposible at this time for Oz to counter such a threat apart from turning off the GPS 'targeting signal'.
baswell re your reference to "airliners, rental trucks, petrol and fertilisers" they are the possible tools of Oz based (i.e. in-house) wanna-be osama's. To date Oz security has a good track record of stopping those bad boys before they get to far - e.g. them footy bombers.
One of the side effects of being very effective at stopping the 'in-house' terrorist attacks is them bad boys have to look at launching an attack from outside the country.....

via baswell #274; Not that it will help our delusional friend BingBoy, but to put things into perspective:...
via baswell #278; You mean all those posts about where the terrorists will get us with GPS guided bomb-drones? And that as such, GPS will eventually be taken away from us?
Oh wait, you just made another one!
Even if it is a credible threat, that doesn't mean GPS is going to go away, is it? Last I heard, we still have airliners, rental trucks, petrol and fertiliser, as well as (in the US anyway) easy access to fire arms.

OZBUSDRIVER, i guess yer refering to Dr Carlo Kopp. How did Carlo go with these other comments from 2008 ?....
"...only to have what they perceive to be civilian freeloaders exploit their system and defeat the built in safeguards against hostile use. As things stand, the deployment of the FAA's WAAS will allow anybody with a suitable commercial DGPS receiver to achieve blind bombing accuracies well in excess of what is provided by basic PPS P-code whilst in US airspace.
This is a nightmare for the USAF, responsible for defending US airspace, as the deployment of DGPS will very quickly lead to a virtual complete dependency of the civilian ATC and traffic management system upon DGPS..."

Using the technology to bring that capability to a place like Broken Hill means the risk of a truckie that doesn't want their boss to track them and using a jammer is very low. At the same time it might well save someone's life as the RFDS would be able to get in at times they might not. (Or some other strip more likely to be in IMC than YBHI!)
And have good rules for alternates; you know when the signal is being jammed and most likely you won't have any trouble 100 miles away...
So yeah, don't be stupid, but also don't let it stop you from deploying this in places where the best you might have now is an unreliable NDB...
.
Yep, nothin to worry about... yet..
Just wait until them bad boys manage to hook up the GPS...
"...The notion that a terrorist group might entertain using a UAV is by no means far-fetched. One recent accounting of terrorist activity notes 43 recorded cases involving 14 terrorist groups in which remote-controlled delivery systems were "either threatened, developed or actually utilized," including al-Qai'da plans to use unmanned airplanes to kill leaders at the 2002 G-8 summit in Genoa, Italy..."

This will terrify the plebs then;
20 February 2012
The trial of an operation using remotely controlled aircraft to monitor beach safety in south east Queensland will require approval from the Civil Aviation Safety Authority.
More information can be found on the CASA website.

Hmmm... via pg 24, Flight Safety Australia, March/April 2012...
"...Australia is at a watershed in its ATM, with many legacy ground-based navaids, such as non-directional beacons (NDB) and VHF omni-range (VOR) equipment, approaching the end of their useful life. The intention is to complete the transition to satellite navigation, which commenced in 1995, by early 2016, while retaining selected navaids to back up and mitigate any problems with GPS..."
Heh, to "back up andmitigate any problems with GPS"... Why the backup ?, whatever could go wrong with the all singing all dancing GPS..?
.....and whats with the "problems"..... not just a problem, we got problems with GPS..

Thats illuminating..
OZBUSDRIVER, from the info yer have referenced here it looks like there has been next to no real research done into the problems with GPS.
Going off the threads here pionting out how the current aviation minister is incompetant its not surprising how little thought (or perhaps just a lot of greed, hang the consequence sorta thinkin) has gone into the matter... ah guess we will have to wait and see what the next aviation minister makes of it all..

Wow! Quick reply. Binghi, I had to think what I was commenting on back then. If you remember, we just had a rare( in terms of the current very quiet solar cycle) solar storm. In hindsight? It didn't amount to much interference. Polarity was favorable for minimal interference.
