Both Galileo and the GPS use the International Terrestrial Reference System as their reference frame, and TAI as their reference timescale. They then derive their own realizations of these idealized systems using their own infrastructure. Although the Galileo and GPS realizations of the ITRS and TAI will be independent, they should match to within a resolution of a few centimeters or nanoseconds respectively, and so should be effectively interchangeable for most low-resolution use.
