    But at least we're getting good news about D12! ;):)

    Comparison of Orbital locations of D10, D11, and D12 by day.

    Thanks Sixto, for the data :biggthump

    Agree....nice work there sir....even I can understand it, which is quite an accomplishment. :lol:

    It sure illustrates how much more "direct" (no pun intended) D12 is approaching its first resting/testing spot, as compared with its previous D11 brother.

    Yeah;

    I would say that D10 actually used the most "direct" (but less energy efficient I suppose) route to GSO of the three D-type birds illustrated here. Whereas D11 and D12 both appear to use about the same more or less "indirect" or circuitous path of going first to a high apogee (>41000 km) super-synchronous orbit before significantly raising perigee up to a certain point before converging both apogee and perigee toward GSO at 38,786 km.

    However D12 is accomplishing its perigee raising and a-p convergence much faster it seems.

    There was a lot more riding on D10. D10 was there first real HD bird that finally gave them an actual HD lineup (more than the 5 they already had). It was a race to get it up an functioning

    i was just thinking the same thing. I also think there is more riding on 12 than 11. D* has temporarily fallen behind.

    True. This will put Dish, Directv and Fios in pretty good sorts.

    Dish does have more capacity, BUT, they are compressing more. The Directv channels I looked at last night after the install, look better on my 55". On my 32", both Dish and Directv look stellar.

    He probably got laid off by Directv! :D The mascot for D12 was not necessary nor affordable anymore!

    Yes, we have convergence of apogee and perogee. ;) But never, I repeat, never cross the streams! :D

    Maybe D12 will be "talking to us" in about a month at its testing location.

    Do you feel with D12 so close to zero inclination that they will soon, or maybe have deployed the solar panels. That is when I will start to relax....

    just to get things clear, is it the case that spectrum 5 really has no hope of every launching a satellite and is probably causing this grief in the hopes of getting paid off by DirecTV to go away? (the outer space version of cyber squatting effectively?)
