GNSS didn't work without the relativistic corrections.

General relativity was (an is) used to predict necessary satellite
clock offsets and many other relativistic correction required to
synchronize satellite, ground and user clocks.

The proper treatment of relativistic effect on satellite clock is
discussed in this work by Neil Ashby, "Relativity in the Global
Positioning System"
