    If the pants don't fit then....ummm

    D12 is fine and will be on service as planned. :D

    I have the same problem. I find that I'm drifting more, too.

    Sixto, be careful with that kind of talk. I'm surprised the web hasn't already gone viral with DBSTalk's declaration that D12 won't be "on" service until late December. Sheesh! :D

    Boeing wanted SAS Americom (AMC-14's owner) to drop a lawsuit it filed against them in exchange for use of the technique. The details are here: http://www.spacedaily.com/reports/B...n_AMC_14_Lunar_Flyby_Salvage_Attempt_999.html

    Another convenient way to visualize the "gap" which I use is the difference from the earth's geometric center to the center of the orbital ellipse. For a perfectly circular orbit this would be zero of course and only theoretical.

    All realizable orbits however have a non-zero gap value with the greater the number the more elliptical the orbit.

    This is technically called "eccentricity." The more an orbit varies from a perfect circle, the greater the eccentricity. In the TLE format, the eccentricity is the fourth term on the second line of elements.

    Now I get it. Next time whoever posts a TLE, can you please put some large sticky notes on those important numbers? The only number in those TLEs that had ever caught my eyes so far is the number "#", I could not figure out any other numbers.

    You can take a look at this page while we wait for the next TLEs ...
    http://www.space-track.org/tle_format.html

    Decoded (as Sixto does in post #1) my favorite three lines are:
    Period 23h 56m 05s (1436.8 min)
    Perigee x Apogee 35 776 x 35 797 km
    Lon 76.0253° W


    When the period gets away from 23h 56m the satellite will be moving.
    When the Longitude goes past 77 it will confirm the satellite is moving.

    When the Perigee (closest distance to Earth predicted) and Apogee (furthest distance from Earth predicted) is well above 35.7k the satellite will be moving. (As Sixto put it, "The guesstimate Drift TLE from a month ago had perigee/apogee at 35,885/35896 for a 20 day Drift.")

    As long as it stays where it is, it's not moving. :)

    It's a vBulletin (page all the way down to the bottom of the screen and see who provides the forum software) reserved word. What it means, is they are Prophets second only to the Three-in-One dieties known as "Admins". A moderator has to be given mod status on individual sub-forums individually. Super-Mods just have it across all forums and sub-forums, because they are just too hip for words, even if not quite ominiscient/omnipresent in their powers like an Admin is. There's other stuff that can be granted them and denied garden variety mods, depending on the all-powerful whim of the Admins. Like they could have the rights to send you to your room for lengths of time, or eternity, on their own authority without further prayer at the Admin altar.

    I tried that one time or another to overcome the curses, I guess they were total waste of time?:) Damn, even God had answered me a few times:)

    But would it be fair to say this "gap" is actually the "eccentricity" or is it derived from it?

    Considering that eccentricity is a unit-less ratio expressing an ellipse' foci distance to the center divided by its semi-major axis. Whereas the "gap" is the semi-major axis multiplied by the eccentricity. :)

    What a relief, I thought eccentricity was bad, but wait till you reach your gap. I guess I am lucky being merely eccentric.

    OK, so, we have waited for week after week for this thing to move and still it sits there. I know the mantra that "all is well" but my brain keeps saying in the background that something is not as it should be. At this point in time I would like to hear from you knowledgeable people as to what your MOST CURRENT theory is for it to still be sitting at 76. Still testing is not a valid answer without specifics. Thanks for your responses.
