    The short answer is they're only doing a functional test. The antenna patterns are done before mating to the SAT at another location.

    Update:

    Intelsat 30/DLA-1 continues to move forth to launch on schedule. If fact so well they can afford some recreational downtime for the launch teams involved.

    Why do some of those reflectors look bent?
    Is this a fake picture?
    Meaning, like a model version?

    Probably not fully deploy that time when the shot been taken.

    The problem there P. Smith is the FCC docs. for IS30/DLA-1 list a total of 6 reflector type antennas for the satellite which are all for the Ku band payload and only 4 are stated as "deployable." The other two are stated as "fixed" in position and do not deploy after launch.

    These appear to be the 6 seen in the photo taken at the CATR. And compared with other photos where the deployable antennas are in stowed position for launch, it appears the four larger undistorted reflectors are the deployable ones, whereas the fixed ones are the somewhat bent looking ones as damondIt points out.

    Update:
    IS30/DLA-1 now fully fueled and attachment to the payload adapter (called "First Mate") successfully done.
    Everything still on schedule for the Oct. 16 launch.

    Is it common to still have a sizeable launch window (111 minutes) this close to launch?

    Where are you getting this 111 minute window from?

    I guess another technical note that should have been posted for IS30/DLA-1;

    A 30 day STA request from 10/25/2014 - 11/24/14 was filed with the FCC by Intelsat back on 9/22/2014 for in orbit testing ("IOT") of IS30/DLA-1's Ku band payload at 132° WL using a 14.3m Ku band dish antenna at their uplink facility in Hagerstown, Md., (Specifically at their "Mountainside Teleport" http://www.intelsat.com/teleport/mountainside-teleport/) and granted on 10/6/2014.

    From Salo's schedule.

    Actually, it is a 51 minute window on his schedule. Someone else's schedule had the window at 20:00 to 21:51.

    For a nice summation of the main relevant activities and technicalities regarding the preparation and upcoming launch of flight VA220 for IS30/DLA-1 and the companion ArSat-1. Download the "Launch Kit" here;

    View attachment 25486

    To help those of us who are not rocket scientists follow along anyway ... :)

    EDIT Addendum: Again the numbers of transponders for IS30/DLA-1 listed in this document make no sense.

    There's the oft-quoted strange 72 figure for the Ku band, where the transponder layout in the FCC docs. show 80.

    And now "10 C-band" are stated where the FCC docs. have only 4.

    But an otherwise good document for everything else that I can see.

    There's that 1:51 launch window again just hours before launch.

    Salo revised his schedule accordingly.

    Mission update:

    Ariane 5 with payload now moved out to launch pad ELA-3. Picture shows it during the process of approaching the pad riding on it's giant "Mobile Launch Table."

    All systems still go for launch on schedule tomorrow.


    Ariane 5 is moved to the launch zone for Arianespace’s fifth heavy-lift flight in 2014

    [​IMG]The heavy-lift Ariane 5 with its Intelsat 30 and ARSAT-1 payloads approaches the Spaceport’s ELA-3 launch zone during today’s rollout.

    October 15, 2014 – Ariane Flight VA220
    The workhorse Ariane 5 for tomorrow’s Arianespace mission from French Guiana is now ready for liftoff following its rollout to the Spaceport’s ELA-3 launch complex.
    Riding atop a mobile launch table, Ariane 5 was transferred earlier today from the Spaceport’s Final Assembly Building – where this vehicle received its dual-satellite payload. With the rollout now completed, the final countdown will begin for an October 16 liftoff at the start of a 1-hour, 51-minute launch window opening at 6:00 p.m. local time in French Guiana.
    This fifth Ariane 5 mission in 2014 has an estimated payload performance of 10,000 kg., which includes a combined total of approximately 9,300 kg. for the two passengers – Intelsat 30, hosting the DLA-1 payload, and ARSAT-1 – as well as the launcher’s SYLDA dual-passenger dispenser system and satellite integration hardware.
    Riding as the upper passenger in Ariane 5’s payload arrangement is Intelsat 30, which will be released at approximately 27 minutes into the flight. This spacecraft was built by SSL (Space Systems/Loral) for Intelsat and will operate from an orbital position of 95 deg. West – from which it is to greatly expand direct-to-home entertainment offerings in Latin America, as well as provide backup and restoration services.
    ARSAT-1 – the first geostationary satellite built in Argentina, produced by INVAP for ARSAT (Empresa Argentina de Soluciones Satelitales Sociedad Anonima) – will be deployed from Ariane 5’s lower passenger position at approximately 33 minutes after liftoff. From an orbital position of 71.8 deg. West, ARSAT-1 will deliver a wide range of telecommunications, data transmission, telephone and television services across all of Argentina, Chile, Uruguay and Paraguay.
    Tomorrow’s mission is designated VA220 in Arianespace’s launcher family numbering system, signifying the 220th flight of an Ariane family vehicle since 1979.

    Final installment from Intelsat blog for IS30/DLA-1 from the launch team at Arianespace in Guiana;

    Reports much the same as the previous post.


    Intelsat 30/DLA-1 Ready for Liftoff!
    [​IMG]By Todd Schilb, Program Manager, Space Systems Acquisition
    Sixth in a series from Intelsat team members overseeing the launch of Intelsat 30, which is hosting the DLA-1 payload for DirecTV Latin America.
    This is the final blog installment for the Intelsat 30 launch campaign. We have completed the final launch readiness review and all systems are ready to go for a launch attempt at the opening of the launch window at 21:00 UTC on 16 October 2014.
    Here you can see the launch vehicle mounted on top of the launch table rolling out to the launch pad – this is about 2,500 metric tons of hardware moving down a railroad track.
    Thanks for checking out the launch blog for Intelsat 30, and be sure to tune into the launch broadcast to view the launch live.

    Yes. T-Zero time, considered alone, is independent of the length of the window.
