    Yes, possibly the "RB-2A" reverse band payload on D12 at 103;

    Satellite footprints for RB-2A spot-beamed into four (maybe test?) markets;

    http://www.dbstalk.com/topic/184044-interactive-beam-footprint-library/?p=2710706

    Again, completely agree.

    The only thing that you seem to be repeating is how you don't understand how the process works.

    The more you post, the clearer it is that you haven't a clue.

    "As an example":
    The two probes/pickups in WRC727D1 [15.9-21.9 GHz] circular waveguide will be 1/4 wavelength ± 5º from "your ground plane".

    Ku & RDBS will not coexist in the same waveguide, while Ka & RDBS will.

    More on 79W: http://licensing.fcc.gov/myibfs/download.do?attachment_key=1004700

    "As originally envisioned and currently authorized, DIRECTV KU-79W would be capable of operating one downlink beam serving DIRECTV subscribers in the continental United States and a second downlink beam serving Sky Mexico subscribers in Mexico, Central America, and portions of the Caribbean. DIRECTV is currently in the process of constructing two Ka-band satellites (DIRECTV 14 and 15) that, when launched over the next two years, will add significant capacity for service to the United States.
    In light of this, DIRECTV decided to delete the U.S. beam and optimize DIRECTV KU-79W for service to Mexico, where it can be used to expand DTVLA’s capabilities in order to support the ongoing transition to HD services in Mexico."

    That's a very good idea. Adding 79º spectrum for CONUS customers would add a lot of hardware (LNBs and probably a whole new ODU) for what would be at best a marginal increase in overall system bandwidth. Given the per-customer cost requirements to take advantage of it, it makes good sense to delete the capability.

    What would be interesting for anyone who has the time and curiosity would be to dig around and see which other companies (if any) have FCC licenses for the 79º slot and see what they're using it for; Directv may have done some horse trading, giving up that slot in return for something else. Or not. It may just be as straightforward as it sounds.

    Yep LL, be cool to give up 79º to advantage something else, we'll see.

    What I question is since SKY Mexico currently uses the Ku band payload on an Intelsat bird at 58w, how does a new proposed satellite way over at 79w fit in to the service?

    Create a new two position elliptical dish covering a 21 degree span?

    A two dish solution?

    Or abandon use of satellites at 58w and re-align all SKY Mexico sub's dishes over time to 79w?

    55.8E?

    That represents a service area including Iran, Iraq, Syria, Afghanistan, Pakistan and on up to Kazakhstan.

    Though the Spacenews article isn't completely accurate as to D1R's recent history;

    D1R hasn't been at the 101 slot in years, but after long serving at 72.5 was maneuvered to 110 to briefly serve as a backup to D5 (Tempo 1). Then just as DIRECTV changed their mind and decided to dispose of D1R from there, they received the request from the RSCC for it, so was moved from 110 to (eventually) 55.8 E.

    So they are going to use it to serve terrorist nations? Lovely.

    True, money talks!

    Now funnel that money into a massive HD channel expansion as soon as D14 is deemed operational!

    Yeah, that's simply the launch window posted in D14's Schedule S filed with the FCC last year sometime.

    Lyngsat is posting old news on this.

    Man ... I usually checkout the FCC's IBFS website every two or three days for any new satellite filings by DIRECTV, principally for news on D14 and D15 and for Intelsat Int'l about anything on IS30 and IS31 for DIRECTV LA. Though Sixto usually beats me to it. :)

    And the site is offline right now due to the government shutdown ... LOL.

    So has anyone else posted this and I just missed it? Without access to FCC filings, I'm feeling annoyingly cut off. :rolleyes:

    Any ideas what role it will play in the Directv fleet? That size is much smaller than the most recent Spaceway 1 & 2/D10/11/12/14/15 class Ka fleet. I wonder if it's for upgrades to the legacy Ku fleet. I'd love to hear some informed speculation from you guys.

    I think it was mentioned before that it's going to DIRECTV-LA and not for the US market.

    Well, there's other stuff in there about the Intelsat leased capacity for Latin America. The first one of those is going up on Arianespace too:

    http://www.arianespace.com/arianespace/news-press-release/2013/9-9-2013-IS-32Satellite.asp

    I'm pretty sure those birds are large Astrium platforms though, like Directv 15, not the smaller Orbital platform mentioned in the press release I linked first.

    EDITED TO ADD:

    Okay did some more digging and it appears you're right, RAD. The tentative Arianespace manifest lists "DIRECTV INNOVA/SKY MEXICO 1" for the second half of 2015. That seems to fit their earlier description of the satellite as a "small Direct-to-Home", when with Orbital's description of this type of satellite bus:



    http://www.orbital.com/SatellitesSpace/Communications/index.shtml

    Orbital Fact Sheet, just FYI:
    http://www.orbital.com/NewsInfo/Publications/GEOStarBus_fact.pdf

    The Arianespace launch manifest also lists Directv 15 as "End of year" 2014. While I'm glad Directv is booking all their flights on Arianespace (currently the most reliable commercial launch provider), they are also widely regarded as the most expensive. Will be good to see SpaceX get a number of successful GTO missions over the next year or 2 in order to put some more downward pressure on launch prices. It would also be really good if ILS gets Proton reliability back up to something reasonable. Between their problems and SeaLaunch's failures (and subsequent corporate collapse), there isn't enough competition in the global GTO launch market.
