A:
The very first measurements of the velocity of light measured light from an extraterrestrial source, the moons of Jupiter. () The velocity of light from high-orbit satellites must be very exactly the standard value in order for GPS systems to work. Various other measurements are done, e.g. bouncing light off the moon and back.
