Sadly, the EU system has a method for the US to shoot it down, as the US said they’d pre-emptively shoot down all satellites we put up unless we build such a backdoor (especially due to the chinese partnership in Galileo).
Now we have a system where the chinese stopped being a partner, and the US forced us to add a backdoor and reduce the quality. I’m not sure I can see anything good in this.
Thanks but I do not see any mention of a backdoor. A different frequency is not one, it allows for local jamming (which is also possible with GPS) and that's all.
The whole point was to put GALILEO on frequencies that overlap with military BeiDou and military GPS, so that no government could jam civilian GALILEO without jamming their own military tech.
The whole point of galileo is to have a system which is not dependent on the US and their GPS switch.
Jamming is a local action, the US will be able to jzm Gallileo like we are able to jam GPS - again locally.
Frequencies can be switched, if we only relied on the fact that they are the same then the US could switch theirs (and have equipment which is compatible if course) and there goes our security.
I work in security and have worked for 12 years for a huge provider of telecom systems and hinestly do not see any real advantages to match the frequencies.
Also, if we had the same frequency, WE could not jam GPS if we wanted to.
Now we have a system where the chinese stopped being a partner, and the US forced us to add a backdoor and reduce the quality. I’m not sure I can see anything good in this.
