In your example the satellite is constantly accelerating, and the ground server is supported in a gravitational field, both or which bring General Relativity into play. You're talking about accelerating frames of reference, and unlike straight-line motion acceleration is absolute. The statement that there are no privileged frames of reference is more strictly that no inertial frame of reference is privileged.

Like I said, I'm pretty sure I don't understand how it works, but satellites being affected by Special Relativity in the form of time dilation is a problem in the real world.
