Flying Spike, If I recall corectly Dick Smith started out in an electronics shop - I imagine he's got a fair idea of electronic type stuff.
Edit - Flying Spike, where you gone
why do ALL the airlines want it?
Good question DH.
Re the Collier prize referenced in Ozbusdrivers post. Have a look at the list of sponsors to the NAA - it may get some thinking.
It would be nice to know the composition of the Collier prize voteing panel.
This thread is ADS-B and Terrorism, but I'd ask again some of the questions covered in depth in other ADS-B threads -
It would be interesting to know the true cost of a fully GPS based ADS-B airnav system in Aus. How many GPS satilites are needed for Aus airspace and how often replaced, how many ground repeater stations will be needed for full ground up use, and to prevent hacking, how much protection will be needed for the ground stations -
will we need troops/police at all ADS-B ground stations? And what is the backup for sun spot activity GPS outages?
