On: Galileo navigation satellite system goes live

[sounds]

To all who are writing that the EU Galileo system is "insurance" against the US's regional denial capability, it appears you haven't thought through how they would do that.

It would not be by turning off or fuzzing the US GPS signal. It would be by deploying vessels with jammers.

Galileo was originally designed to be on an independent frequency, and the US has pushed to have it so close to the US GPS frequency that jamming will effectively kill both.

Not great insurance.

This (as I wrote in another comment) is the exact opposite of what actually happened [1].

Ok, you are correct.

Galileo was originally designed to use the same frequencies as GPS.

Now they use different enough frequencies that Galileo can be jammed without jamming GPS. Of course, jamming both is also possible.
