    Plus it must go through some very long testing process to make sure everything is going to work and keep working since you can't go up and repair it once it's been launched.

    Yep;

    For instance notice the extensive test-bed procedure posted by Sixto back in April run by SS Loral just for proof of performance for the 17/24 GHz RDBS band antenna.

    Its also of note there that acceptable results of this test must be submitted to the FCC at least 9 months prior to launch, which confirms a launch sometime in the first quarter of next year.

    Not to mention that SSL probably isn't standing around doing nothing at any given time. Orders aren't going to go to the floor for assembly the same day as the order is received.

    Nothing happens until the commitment is made by the customer. Once the customer signs the paperwork then things start happening. Material Requirement Planning. Manufacturing Capacity Scheduling, etc.

    I can only imagine that many of the components of both the main satellite bus and the payload are high dollar items that are made to order. They aren't kept sitting around on the shelf anywhere. Not at SSL. Not at the vendor who supplies SSL. So SSL orders what they need. Based on the lead times of those items and the existing workload, the manufacturing can start being integrated into their schedule. It isn't uncommon for the components to carry lead times of multiple months.

    The vendors to SSL also will have to place orders for materials and schedule their work and purchasing in response to the orders for components that SSL makes. There will be lead times associated with those as well. And this will be a consideration for several levels as you drill down through the Bill Of Materials for each item that goes into the end product.

    But with the dollar cost associated with all of this stuff, most vendors and manufacturer's aren't going to do anything until they have a signed order in hand and they don't tie up big money keeping any of this stuff in stock. Every bird is built to order and is customized to boot. Thus it takes a very long time for all the pieces, parts, components and assemblies to come together at each level and ultimately trickle back to SSL for final assembly.

    All things considered, based on my history in manufacturing and materials control, three years sounds about right.

    The discussion seems to have taken for granted that receiving the downlink signal is a foregone conclusion. I submit that the cart has been put before the horse.
    Absent documentation or demonstration of some type of antenna that can pull off both bands and still qualify under OTARD, I have to ask how.
    DIRECTV has their fingers in many pies in terms of the services they offer so I'm not convinced it is all for naught. I'm just trying to figure out if it can be used for residential use or it is an alternative to spending bandwidth that residential service could benefit from by shifting commercial traffic to the new band.

    DIRECTV has long demonstrated a willingness to camp on bandwidth that they don't effectively use for residential service (see more at DIRECTV 5).

    SSL began construction (Q2 2010) on DIRECTV 14 nearly four years before it is expected to launch (latest guess is "early" 2014 according to Salo at nasaspaceflight).

    So you know all the results from all the testing they did with the test packages they installed on the last two satelites they launched? They already know what they are doing and how to use it, they just haven't announced it to anyone.

    As I stated, for mainstream programming you may have a point, but for niche there's still lots of time to reveal and deploy subscriber gear. And what substantial non-subscriber commercial traffic does DIRECTV carry that shifting it to the RDBS band transponders will be of benefit?

    I mean DIRECTV is not like a Common Carrier.

    Do you have another example of this alleged "spectrum squatting" by DIRECTV?

    Since DIRECTV-5 (Tempo-1) is currently serving a very important role for Puerto Rico subscribers. So DIRECTV is hardly spectrum squatting at 110 at present.

    I don't really understand the time line. How can it take 4-ish years to construct a satellite? It’s a modular platform they’ve been building for over 25 years.

    We construct and deliver two Virginia Class Submarines in that amount of time. I bet the basic platform is constructed ahead of time and is waiting for a final decision on the broadcasting equipment. There’s got to be a lot of time spent waiting, otherwise how could it take 4 to build?

    Could be there's a lot more realestate work work in with a sub so many different areas can be worked on at the same time.With the satellite even though parts of it are modular there's not a lot of space for a ton of people to be working on it at the same time. Plus things probably get slowed down due to all the clean room precautions that must be taken that aren't needed on most of the sub.

    don't forget - each sat is unique to latest technology and particular latest requirements from the customer [DTV] hence RDBS example - TWTA and antennas for sure

    I wonder if the RDBS technology is destined for some other company? Is it possible that Directv has been doing all of this testing for someone else?

    Nah it's for them. Otherwise they would have disclosed that in filings. FCC and likely sec ones.

    I still suspect it will help with several things including 4k and Video On Demand and maybe someday sub channels from locals.

    I think 4k makes sense, especially if they have to swap out LNBs or SWiM modules. If they are getting paid upgrades to 4k, it lessens the financial pain of replacing equipment.

    nah, 4k doesn't make sense either ...
    how many customers out there now and in 2 years who will have 4k HDTV ? spending millions for a sat and new antennas and new receivers for 1000 customers ? nay, not going to be that purpose for RDBS, nope

    I suspect it has a lot to do with the fact that SSL has many (if not most of the class' production) satellites coming together at once. If it wasn't satisfactory to DIRECTV, you might imagine they would have had other options.

    SSL doesn't have a long-standing record of promising a delivery and missing it by large fractions of a year as Boeing seems to be given to.

    Absent an OTARD compliant antenna, what good will it be? Even wealthy subscribers are limited to the protections provided by OTARD.

    nasaspaceflight has an ESA subforum that has a thread with launch schedules. The poster's handle is Salo.

    We've delivered 6 subs in a year and Newport News has built an aircraft carrier is same time it'll take to build DIRECTV 14...just sayin' :grin:

    After thinking about it, I suspect the timeline gives a long lead time to procure and install the sub-systems spreading the capital costs over four years.

    I'll bet, given the components, they could build the satellite in a few months.

    I have not seen anything that would suggest a larger reflector would be needed. Have you? If you haven't then you're just fueling FUD.
