  2. Yes... The communication with GPS satelite uses (amongst others) relativistic effects (time-dilation) due to the relative motion and the difference in gravity field - but don't forget one big other factor in GPS is the density of the outer layers of the atmosphere and which necessitates corrections for the difference in speed of light through different dense mediums..
