    Ok there was a regional sales guy for directv in the store where I work this afternoon, and he said at September 15 is national HD lunch day.
    New satellite are not, they are holding back space on Spaceway 1 & 2 to make it work even if something goes wrong with Directv10.:rolleyes:

    Assuming I got the EDT - to - UTC offset right (I always forget exactly how many hours it is -5 during DST?), D10 was at about 103.38W at 7:00 a.m. EDT.

    That would explain why D* hasn't added more MPEG4 locals even though the Spaceway sats have the capacity.

    Did anyone notice the Discovery Channel (278) is showing programs in the guide as HD? It is still an SD signal...

    I'm seeing the same thing, it's probably just erroneous guide data.

    Any reason why Space Track would not provide updated coordinates?

    Sorry but I don't buy that logic. If D* could make SW1/2 do CONUS coverage why would they not use it before to provide more national HD channels for a number of months now? Put the channels up on SW1/2 and once D10 goes active then migrate them to D10 and continue HD-LIL rollouts on SW1/2. They'd be able to hold onto customers that moved to E* due to nothing new until D10 and they couldn't wait.

    Did you ask him how they are going to use SW 1 and 2 [spot beams] for nationals?

    SW1 and 2 used phased-array transmitters - they can be configured to pretty much any configuration of spots or even CONUS, albeit less efficiently.

    -5 hours to CDT. -4 hours to EDT.

    Space-track.org doesn't have new numbers because the orbit hasn't changed.

    Regional sports or anything else but not national. As someone else said, if D* could use sw 1-2 as national it would have been done months ago.

    So, did it go PAST 102.6? Will they swing it back, or is this an error in positioning (again)?

    It's going to keep moving back and forth, round and round, until its orbit is geostationary. Since the orbit hasn't changed much - eccentricity and inclination are still too high - you can't call it parked yet.

    Don't worry about what its longitude and latitude are. They don't matter yet.

    Watch the eccentricty to see how circular the orbit is. It needs about four leading zeroes.

    Watch the inclination to see how far it's tilted off the equator. It needs to probably be under 0.1 from what I can tell.

    When these numbers are close to zero, then the longitude will have some meaning.

    Is D10 "late" in it's parking? Or was the aforementioned August 10th date just a guess on when it would be parked?

    (sorry...just some questions from a layman...I don't understand all these rocket science mathematics!:))

    I would say it was probable a rough estimate.

    Since D* asked for permission to begin testing on the 10th I would say its "late" however with the lack of updates who knows where it really is right now, also what testing would they have been talking about? Uplink downlink tt&c? I would think they are moving as fast as possible to get this done and will do whatever it takes to get it online asap.

    Not quite sure how to read the rolled eyes, but here is some reality. S1 and S2 were hoped to be able to provide some CONUS capability and there are some FCC documents to that end. But in actual use, the power draw needed to send a CONUS signal was too great so that was abandoned.

    So a question might be are they holding back some spotbeam capacity? I haven't done the math, but for redundancy's sake I know that I would. :)

    Cheers,
    Tom
