in thread Converting GPS seconds to readable time&date

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.

    "That's a little more complicated: due to both SR and GR, the net result is time passes faster for the satellite.".

    That talks of the passage of time, not speed, or is the same thing in relativity?

      I'm still scratching my head...:-) Things were so clear, and the world was so orderly this morning, until tye threw in that monkeywrench. Now I'm a puddle of random thoughts.

        Maybe this will help. Or not.

        I'm not sure it really clarifies things much as it uses the usual example of something (a space craft) that moves directly away and directly back to earth. Whereas, with the satelittes, once in orbit, their relative speed is 0, although their angular velocities are wildly differing.

        So maybe the relativistic affects only apply a) as the satallite achieves orbit; b) as its signals return to earth.
