in thread Converting GPS seconds to readable time&date

That can't be right. The circumference of a geostationary orbit is much larger than the circumference of a ground level orbit, so that means the satellites must be moving much faster than someone on Earth to move in sync.

groud level orbit = 0.46 km/s
geostationary orbit = 3.07 km/s

      #2 just repeats a part of what I said? I don't know anything about relativistic effects, but the satelite must be moving a lot faster than someone on Earth

        Well I have to agree with you, which is why my original reply suggested we age faster, but from what I could gather from the discussion at that physics forum, something occurs that is not compliant with common sense( just what would you expect with relativity :-)) . The result as stated: "That's a little more complicated: due to both SR and GR, the net result is time passes faster for the satellite.".

        I guess the proof is in the pudding as they say, and I wonder what the correction factor is ? A plus or minus? And does that mean it's aging faster or slower?. Anyways, we know it's different rates.
