Some Local HD nationals on 77 Conus?

[spear61]

I was reviewing Aransay's 77 Mexico thread and saw the reference to the request to move E8 to 77 for US transmissions until the new QuetzSat satellite launches in 2011. The request to move says that E8 will not be using spot beams at 77 but would be doing some Local into Local. This suggests that some of the local HD's may be on a close to Conus footprint if I am reading correctly.

If this works out, the AMC 14 failure problem is resolved and Dish will have the horsepower to match Directv by the end of the year (with Ciel 2).

how old is this sat?

The E-8 satellite was launched on August 21, 2002.

A little more detail --- E2 will also move to 77 with E4 scheduled for retirement. E2/E4 will have some some transponders in service allowing E8 to operate at max power using less than the full 32 transponder set, all in all, providing a strong and full signal set from 77 on all 32 transponders. This is going to be a major service upgrade for Dish!

thank you

pardon my poor math skills, but, don't the dbs slots require 9 or so degree's separation? I've been through the pdf, and it would seem to me, that echo8 operating at 77w, aimed at the Continental USA, will still interfere with the Canadian bird at 82w, and future 72.5w.

Could someone care to explain to me how Dish plans to pull this one off?

ITU assignments for Region 2 originally had Mexico controlling slot 78 for BSS 12.2-12.7. Subsequently, they filed and got that slot changed to 77. Echostar will have to assume responsiblility of non-interference with adjoining BSS satellites or they will not get permit. But, the ITU plan addresses the technical details of that problem. The principle concern would be interference if 72.5 and 82 were using a single dish for reception of both satellites. Echostar will be leasing Nimiq 5 capacity from the Canadians at 72.5 so one can assume that both parties are working together and have a common business interest in making it work.

"Geostationary orbit positions under the Broadcasting Plan

6. In accordance with appendices 30 and 30A of the ITU Radio Regulations and
under the plan for a satellite broadcasting service in the band 12.2-12.7 GHz in
Region 2, Mexico has been assigned the following geostationary orbit positions and the permanent rights thereto: MEX01 78° N, MEX01 69° S, MEX02 136° N and
MEX02 127° S.

7. In that regard, the Government of Mexico has submitted an application to the
ITU Radiocommunication Bureau to amend Region 2 plans to include the
movement of the original position of 78° W to orbit position 77° W and the
extension of its coverage to the territory of the United States of America.

Now we can see why Dish leased 16 transponders in Nimiq 5-72.5.

72.5-77-82 will not interfere with each other if the odd and even transponders alternate to US or Canadian or Mexican reception as one progresses across the arc (effectively maintaining an approximate 9 degree spacing at the receiving location). We can expect something similar to happen at Dish's 86.5 slot. So in the long term we see Dish joining forces with the Canadian and Mexican satellite providers to better manage their spectrum.

Does this mean the most Dish can use for U.S. is 16 transponders at 72.7w and 16 at 77w?

No. It all depends on their agreements with their Canadian and Mexican partners that control those two slots.

In reality one will probably see something like 50% US and the other 50% into the neighboring national markets for these two locations.

Isn't that 16 and 16?
