Galileo will be independent but the two systems should be compatible. This
means that all the civil users in the world will be able to use the two
systems easily, with only one receiver. It should be fully transparent for
the users. .../...

To expand a bit, the recievers will need to be designed to do this.
There are only 32 possible GPS codes, and only 31 (?) of those can
be used. (IIRC there are about 28 operating GPS satellites, with a
nominal 24 bird constellation).

The two systems can share the front end of the reciever easily.
Most of the decoding will be totally different.
I note that GPS/Glonass chipsets are available.

Anyways, what is meant by comaptible here is that one can jam one
positioning system without jamming the other. Oddly enouugh, US
insisted on this to be the case (appart from trying very hard to
convince EU not to go with Galileo in the first place).
