Thanks for the info, guys. I am exciting about D12 already and D11 isn't even 'in service' yet.

Is this thread going to be a 'Sticky'?

I'm sure there will be a sticky but it may be a bit early. However, there seems be a lot of interest in a sticky so who knows. :grin:

You'll know it when it happens. ;)

well if the satellite is already completed, why are they waiting a year to launch..

Get it up there now.. Call the Astronaut Farmer.. I am sure that some guy, who was preparing for the Millennium explosion has some sort of launching device in his back yard. We have guys around here that have CB's that are stronger then the radio stations.. I am sure some one can throw that thing up there sooner then a year.

Some kid working on his high school science project.


Get it up there. the new satellite is almost full. and it hasn't even been turned on yet..


I suspect it's also a matter of not having a need for it. Once D11 gets up and running and filled up DirecTV should be very close to carrying all the HD channels that are available to carry. Launching another expensive sat to add another 5 or 10 channels isn't really a good idea financially. Since it's one big expense they do need to make sure there is use for it.

There is also the other side of things to consider. There's a lot of infrastructure needed on the ground to handle these in addition to the sat in the sky. They need facilities to transmit the signal to the sat, hardware at those facilities to compress and combine the different signals and some way to get the info to these facilities in the first place. All of this takes time too and you can't significantly accelerate these plans with out greatly increasing the cost.

As a compliment to Sixto's excellent work, this thread has a very good chance of being the one that get's stickied. Normally this would be earlier than we would sticky something, but this thread has shown it has legs :)

So I have a question. Is Directv putting D12 at 107 degrees WL. I am not sure what this filing means. Perhaps those who are a more smarter than I am can explain.

Thanks

Actually, this refers to RB-3, a planned BSS bird. Read about it at: http://fjallfoss.fcc...ent_key=-141467

Just to make things interesting, RB-5 is planned for 119, so all the people complaining about line-of-site problems to 119 will get a chance to it again.

I would like to be the first in this 200 page (at the very least) thread to ask the following:

1) When will it go live? (My guess is Wednesday February 15, 2010)

2) Will this mean less 'compression' on my 175 HD channels?

3) Do you think Fox News HD will be re-mapped?

4) Sixto - what the hell is a TLE?

Thanks in advance..........

I just don’t see how D12 is going to fit into the mix as presently configured. As other than an in orbit spare. Or maybe contribute more spotbeams. Since all the Ka B-band CONUS transponder frequencies are pretty much filled already at both 99 and the 103 slots by D10 and D11. And the 101/110/119 slots are out of the question.

Therefore the advertised increase to 200 national HD channels with the future launch and deployment of D12 cannot be correct with the current receiving equipment. :nono2:

Depends on how they rework the stack plan

By “stack plan” I assume you mean the "stacking" of the LNB down-frequency bands.

But how can you actually rework the current 13V/18V or + 22KHz controlled Ka-lo 250-750 MHz (R/LHCP); Ku 950-1450 MHz (R/LHCP); and Ka-hi 1650-2150 MHz (R/LHCP), stack plan with the present subscriber reception gear? :confused:

Assuming they launch D12 still configured like D10 and D11 with only KA low transmission capabilities I expect they will end up playing around with the conus and spot allocations. Currently the spot patterns for the the Ka spots seems to be pretty loose with many people seeing lots of 0's.

Lets say they put d12 at 99. They bump the total conus transponders there from 14 to 18. Half from each d11 and d12. They tighten up the spot patterns from 99s to add more spots to both increase total spot capacity and to move some spots back off D10. D10 fires up more conus transponders from 103c. Net effect of more conus and spot capacity. Yeah it would be simpler if they had a nice empty spot to put it in like d11 at 99 but a single sat at each location isn't enough to fill the entire 500mhz ka lo band especially with quite a few channels to use for spots. DirecTV has 4 sats at 101 to fill that slot up. They've already shown they can fire up extra conus transponders with d10 running 16 instead of 14.

The other possibility is a small? retrofit to d12 to use ka hi instead of ka lo. Ka hi at each slot currently only has spaceway 1 and 2 which use no conus transponders and have the advantage of using the phased arrays so are very flexible to be reconfigured while in orbit.

Either way I'm sure DirecTV is already planning this out or they wouldn't be going through everything to launch D12.

Personally I suspect the first is more likely since they are only stating an additional 50 channels from d12 compared to the 75 d10 and d11 have been providing basically. Either way they do it they won't need to do anything with the stack plan. The only reason they would need to redo the stack plan would be if they where receiving another 500mhz block like Ka lo from 101 but as far as we can tell our LNBs couldn't receive that and its actually already in use for backhalling by DirecTV.

I would like to know this as well, as anything west of 99/101/103 or so will be a problem for me, at least with a single dish installation.

Man, just when I think I am "out of the woods" and will only need 99/101/103 from here on, I get this news about these BSS satellites and their to be at 107w and 119w.

Any speculation of what specific services DTV intends to use these for?

Welcome.

1. Hopefully will go "live" late 2009. Most likely 60-90 days after launch. No idea yet of launch date or launch provider.

2. D12 will add capacity for at least an additional 50 HD channels. The additional bandwidth most likely will not effect "compression" but it all depends on the bandwidth requirements in late 2009.

3. Best guess is that Fox News HD will be "live" very soon. I'm guessing 8/14 but nothing has been announced.

4) TLE description is in post#1.

I read the whole D11 thread as it happened, and thought I'd get that stuff out of the way before you were inundated with it again (I knew the answers).
