Hi Bob
You said"
What will happen if the Galileo goes up is that no European airport will allow a commercial jetliner to land without the Galileo system. This will inevitably lead to this basic system being in world wide use for navigational purposes ------- Does this imply that all airliners going to and from EU and US will have to have both Global positioning system ? ( Galileo and the US GPS) It would appear that the country to which an aircraft is approaching could demand a specific space navigetion syetem to be used.
As I understand the current Galileo event : It is in test phase. No actual system funding has been established. No list of users have been verified to be real supporters. The use of the US GPS system does not cost the EU anything. All EU users of the current US GPS system will need both if there is no global support for a single system Without a Amateur satellite using a mode L up link that uses narrow analog and/or wide band digital modulation ( which could change over time ) the Galileo testing is not really testing for amateur interference.
