Echostar applies to move Echostar6 to 77w

well let's hypothesize...Directv has it's 5 sat dish which covers from 93W to 119 W...A spread of 26 degrees..61.5 and 77 are 15.5 degrees apart. Plus Dish has loaded in the software of some receivers and orbital slot at I think 82 degrees( please correct if I am wrong here)...So it is conceivable that Dish could use a single dish solution for 61.5, 77 and 82...My thinking is that Dish will cut the country into thirds. this is based upon what I have read where Dish is proposing a single dish solution for all subs.
They don't need to split it in thirds. The Texas HD locals were uplinked to 61.5 yesterday. So I'd guess that E* will split the US in halves -- Eastern and Western Arcs -- with Dish1000 like dishes targeting 2-3 sats. IIRC with MPEG4 they can get all the stuff on just two sats.

So when the uplinked Austin HD locals are "available" sometime in April (he posts hopefully), I'm expecting to hear the clompity-clomping of a Dish tech on the roof installing a new LNB and re-pointing my Dish 1000 eastward for an all MEPG4 service :)

E6 does have some dead transponders i think but it should be more than enough to cover all 32 TP's when coupled with E4... all be it the signal will suck!

I hope they uplink San Antonio HD locals too. They are still missing on 61.5. They added Dallas and Houston yesterday but not San Antonio.

At least you guys already have HD locals :) Seriously, I wondered why San Antonio was not uplinked too.

What's all this talk about dish getting 82W? That's currently being used by BellExpressVU to deliver their HD programming.

72.5w is also a Canadian slot that DirecTV is leasing to provide locals.

Well there you go providing factual information.

Don't you know that facts just get in the way of good, clean, idle speculation :rolleyes:

The 9 degrees of spacing allows a single dish multi satellite to work better. Essentially the multisatellite dishes are a compromise, designed to work best in one spot. As you move farther away from the spot the more out of focus it gets (you can aim at one satellite but the others get more out of focus). The large spacing allows them to still pick up a signal from a larger geographic area.

If Dish has a satellite at 77 and Telestar decides to provide service with a triple dish pointing at 72.5, 82 and 91, areas that are far off the designed center point can have the focus of the dish moved far enough that 77 starts to interfere (most likely with 72.5 since 82 would probably be peaked). The dish would probably work over most the useful area anyways (NW Canada pretty low on Horizon to see 72.5) if it was locked on peaked. Of course Dishes tend to get blown around and such getting out of alignment, having a satellite at 77 would make a dish fail to get signal when it otherwise would.

Of course there are ways around this. Dish could work to keep the 77 satellite pointed more south, making reception more difficult in the northern US, but possible with a larger dish. If the Dish satellite fades out before it becomes a problem in Canada, they could minimize interference, especially if they make it south and east and not hit western Canada.

Both the 86.5 and 77 slot FCC grants have quite a bit of discussion about how Dish has to work with Canada DBS companies to prevent the interference or not be able to broadcast from these locations.
 
The reason for the 9 degree sat orbital spacing is the original 18 inch dish size. With small dishes, you need more orbital spacing for a clean signal, larger dishes can use closer sat spacing. The multi-LNB dishes are a little bigger to compensate for the LNB off-center signal loss.
 
Probably they are trying to create another 3 set of satellites. As some one mentioned you need more than 2 satellites to make an arc.

Just like they have 110, 119 and 129 using one dish, they are creating another 3 satelites to use the similar type of dish.

two of them would obviusly be 61.5 and 77. The question is which one is the third one.

Does any one has an idea of how long this will take before they announce the new eastern arc.
 
Funny how we always seem to think of things from our perspective (i.e. seen from the ground three satellites form an arc in the sky).

Another way to look at the "eastern arc" is from the perspective of the satellites in the vicinity of 61.5. Their signal pattern forms an arc of coverage on the eastern part of North America. From their perspective it only takes one sat to form an arc :)
