    Man, you'd think something would pop up for DirecTV 12 already. If it is September as everyone guesses, then we likely won't see any filings until June or July, right?

    Not necessarily...in the past....90 days was enough time.

    It seems to me that Directv and Boeing have a pretty solid working relationship with the FCC by now (and I'd say that goes to all satcom providers and manufacturers who've been doing this for long). I strongly suspect there's a lot of unofficial interaction between the parties and the FCC technical staffers for months and years leading up to the actual filing of requests to the Commission itself, making the paperwork rather pro forma (there I go throwing Latin in, just because :p ). I don't know if we'll see paperwork until perhaps as late as August or even early September.

    From the recent postings at nasaspaceflight.com, it would appear that the Proton-M/Briz-M schedule is slipping a little bit. Sirius FM-5 has moved out bit and Nimiq 5 is scheduled for September as well.

    8 April 3 Eutelsat W2A
    middle of May ProtoStar 2
    June 29 Sirius FM-5 (was beginning of June)
    July 15 - August 15 AsiaSat 5 (likely towards latter?)
    September Nimiq 5
    end of September DirecTV 12
    fourth quarter Arabsat-5A
    fourth quarter Intelsat 16

    Pro forma, is that like or near a priori knowledge? :)

    Well, it is true, but there is likely several bureaucratic processes within all facets of getting this to be ok'd, combined on Boeing's side, DirecTV's side, and the FCC. In that I suspect that through all those chains of communications, folks are working closely so that when the time comes they've essentially to rubber stamp it. I wish we had an insider to give us tidbits of information. :)

    Yeah, and for the benefit of certain basset hound lurking around here, SiriusXM has had a whole slew of independent issues of its own (not the least of which is that until a week or two ago its stock price had been flirting with 13 cents a share for most of the last four or five months . . . :rolleyes: To the extent their particular launch is slipping it's quite likely that it's a result of delayed progress payments to the manufacturer or ILS, not due to any systemic slowdown on the part of ILS. The last Proton/Briz failure was several launches ago and none of the recent launches have had any issues.

    If you do the math, there's not really much chance of squeezing in two launches in September if the previous launch is near the middle of August.

    In looking back, the fastest turnaround has been 14 days between launches. Most launches have been at least a month apart.

    I seem to also remember you telling us D10 couldn't POSSIBLY be moved to its final slot and begin testing as quickly as it did, too, back in the late summer of 2007.

    Needless to say, we ought to just wait and see what happens. :)

    Certainly that's the only true "predictor" of actual performance, but I think it may be helpful to temper expectations with the judicious application of history.

    Did he say that about D10 too? I distinctly remember him not getting the special testing D11 was doing and saying in July 2008 that it would take two to three months for D11 to begin broadcasting.

    I do think there's a probable chance that D12 won't launch exactly on time, but by his own facts and his own math late September is entirely feasible. I would rather be a bit too optimistic than automatically always assume the worst.

    I happened upon this text from the recent DIRECTV 10K filing. I'm thinking that the orbital slot information must be in error:

    Why not, it will be perfect Ka trio - 99/101/103.

    1. Too close.

    2. WB68 stack plan wouldn't seem to support it.

    Can Ka and Ku even be done with a single horn for the same slot?

    In 2009, we expect to begin broadcasting movies in 1080p high-definition as well as introduce a new feature called Score Guide which will provide customers with instant access and up-to-the-minute game scores from the major sports leagues at the touch of a button.

    Currently we have several applications pending before the FCC, including applications to launch and operate future satellites to support DIRECTV's services

    1. Isn't an issue. 2 degrees is the spacing for KA sats and Directv does have the ka license at 101.

    2. Would definitely be an issue. They would have to do something major with the stack plan.

    The ones you missed are

    a) ka at 101 is already use for backhaul via d7 and d8

    b) everyones lnbs would have to be swapped before anyone could receive ka from 101 from all indications we have. Would take to long and cost too much for that to possibly be the plan.

    I don't see much problem with 2° spacing using 1m with HH-motor, AU-9 is close to that size.
    Stack plan could be done using new kind of 'BBC-2'.
    AU-9 use one feedhorn for 99°/101°/103° already.

    I feel the AU-9 triple LNBF didn't say last word about Ka from 101W. Could be some unknown provision inside.

    I have used quad-ridged waveguide feed horns which worked from 2-18 GHz. They were pretty large (about a foot long) but one for 12-20 might be practical.
