    I never said I was researching Sea Launch. If ILS has an "easy to follow record", my question remains. I'm just trying to gauge if we're still on pace for a launch in 90+ days from today.

    The short answer is "Yes." The more precise (and perhaps more accurate) answer is, "Yes, so far as anyone knows publicly." The satellites are typically delivered to the launch provider 4 - 6 weeks ahead of the scheduled launch, which would mean D12 has to be delivered to the facilities in Baikonur by around mid-August (around 60 days from now, give or take). Similarly, documentation and approval for launch, testing and operation of the satellite will have to be filed with the FCC some time in advance of launch. However, as I noted the other day, SiriusXM's application for permission to operate their FM-5 satellite was submitted roughly the same time frame in advance of launch - 5 weeks.

    So, given that the more public steps in the process don't normally occur until 4 - 6 weeks ahead of launch, and we're still a couple months from that time frame, we can confidently say that nothing yet gives any indication that the late September target is off.

    Typically ILS has managed a sustained rate of approximately 1 Proton launch every month or so, though once they had two launch campaigns only two weeks apart. Assuming the payloads are ready on time, the holdup in a higher launch rate is usually booster/upperstage production and processing, not the launch operation itself.

    Sirius FM-5 now has a date (posted 6/18) ...
    Code:
    June 29             – Sirius FM-5 – Proton-M/Briz-M – Baikonur 
    beginning of August – AsiaSat 5   – Proton-M/Briz-M – Baikonur
    September           - Nimiq 5     – Proton-M/Briz-M – Baikonur
    end of September    – DirecTV 12  – Proton-M/Briz-M – Baikonur

    Other than the fact that there's already a September launch scheduled (Nimiq 5)?

    The launch campaign preceding that one is AsiaSat 5 in "beginning of August." That leaves 3 - 4 weeks for Nimiq 5 in "September" (presumably early September if the satellite is ready), and another 3 - 4 weeks for Directv 12 at "End of September." As you are well aware, and as I have already posted more than once, ILS usually runs one Proton a month more or less, but has done two in two weeks before. If the payloads are ready and if Khrunichev can deliver the boosters to the launch complex on schedule, ILS can launch them in the alloted time.

    Also, given that the predicted launch date of SiriusXM FM-5 is now late June instead of the originally-projected early July and it's quite clear that ILS has the time to mount their launch campaigns, pending availability of the Proton/Briz boosters. In fact, given that FM-5 got moved up, I wouldn't be surprised if the rest of the schedule shuffles around a bit and everything slots into place in roughly 3-4 week increments throughout the summer and into fall.

    As you are well aware and as I have posted before, the last time they tried the two week turnaround the launch vehicle went boom and scattered the payload and a whole lot of propellant all over the downrange. DIRECTV hasn't had a catastrophic launch failure in quite a while and with something as unique as DIRECTV 12 (there wouldn't seem to be anything aloft or on ground that could replace it), they can ill afford to try to set or tie any records.

    September/October. The net is hopefully it will be soon. We have 3 satellites in front of D12 so much activity prior to any launch of D12. If all goes perfectly, then maybe September. If all doesn't go so well, then maybe October or later ...

    Nothing like a little catastrophizing to get the last weekend of spring off to a happy start, eh Harsh? :lol: I can see why you take such an interest and appear so worried about the future of D12, given your status as a long-time subscriber and all. Oh, wait ... :)

    What interest would a Dish subscriber have in all this, if not to only present a "doom and gloom" forecast.

    Just because Dish had a catastrophe sat issue doesn't mean its the norm or commonplace like you seem to make it sound.

    D12 is moving along just fine, thank you, with or without those negative propagandized views.

    Ah .. Mr. Gloom and Doom I see. I'm pretty sure if I get into a head on collision with a semi on the way home today that I won't be here tomorrow. However, I'm still going to drive home. :rolleyes:

    Wow, I had no clue harsh was with DISH. That explains the pessimistic point of view. :)

    Yeah, he's with Dish, but I don't think you'll ever hear him say that. I wonder why he spends so much time here, since he has no DirecTV account or equipment.

    Ah well, such is the way of open forums. Be careful who you listen to... you never know who they really are.

    I like to think that the view I present is a little more realistic. Without access to the insurance bonding and other key milestone information, we have only educated guesses and history to go on.

    I don't believe that comparing D12 to an SDARS or failed satellite launch is apples-to-apples. D12 will presumably be the third launch using the Proton M/Briz M Enhanced platform so the history may not be entirely comparable.

    I also don't believe that you have to subscribe to a particular television entertainment delivery service to follow any and all kinds of orbiter launches.

    So who launched D10 and D11, are they not the same launchers for D12?

    Thanks

    D10 was ILS (same as D12).

    D11 was SeaLaunch.

    I realize we still have not been told by DirecTV where D12 will be slotted and how its use will fit in with the the overall Ka band plan.

    In that context, my question is this - assuming Spaceway 1 and 2 are presently fully allocated (I realize they are very flexible) has DirecTV even fully allocated the bandwidth/transponders on D10 and D11? There had been a lot of speculation as to additional national HD channels this year which has not materialized, so I am wondering if D10 and D11 are indeed tapped out or is DirecTV holding back just on economics? Or will the presence D12 allow a reshuffling among all 5 Ka birds that will make for a more efficient frequency usage plan?

    In regards to SW-1 and SW-2 the question is more about LIL.
    Full capacity has not been determined and has many variables and may be limited by "uplink" capacity more than anything.

    What has kept me interested in this thread:

    http://www.dbstalk.com/showthread.php?t=159419

    Has to do with LIL distribution and channel capacity.
    No one has fully addressed the expectations from SW-1 and SW-2.
    Some "problems" were alluded to early but to me the spaceways are a "BUST"

    Data may be incomplete but gct's analysis has been fairly consistent.

    If you take the LIL Transponder Channel map and sort by satellite , interesting and somewhat disturbing info about spaceways emerge.

    SD:
    101 - 669 channels
    119 - 483 channels
    72.5 - 196 channels

    HD:
    D-10 103 - 353 channels
    D-11 99 - 391 channels
    SW1 103 - 120 channels
    SW2 99 - 41 channels??

    This can't be what Directv had in mind when it "bought" into converting SW's from data to LIL TV usage!

    Directv has been moving locals off the Spaceways to D11-D12 i beleive to use them for locals in markets not covered by the fixed beams on D11-D12 and possibly a movie download service like XstreamHD. Just my guess.
