Did a little more digging. The "Effective Output Power" is 91 Watts for Wide Area Canada, 155 Watts for Conus and averages 9.3 Watts for each of the 55 spotbeams.

Could you be so kind as to explain your figures in light of Rocatman's post?
Using simple math and the information posted by Rocatman I would have thought the number should be much higher.
confusedTIA,

This I don't understand - why would Dish want to hide the testing and eventual movement & activation of a new satellite? Seems like they would be offering information to this forum, which is mostly their subscribers, telling how their testing is proceeding and how their service will be improved once the satellite is put into service.
Dish needs to follow NetFlix/Roku's example and participate in this forum. Roku personnel monitor their forum and problems and questions are discussed and answered. Roku has actually picked up on user problems and issued software upgrades that solve problems, add services, etc.
Dish - where are you? Any help or information you can offer here would be appreciated!
There was mention on the last Dealer Chat that testing was going well. There has been no chat since then. Initial testing of Satellites is conducted with analog signals. No digital programming content or anything like that is allowed at the testing location, especially if that location is not the location where "operation" is authorized.
It is just a bunch of engineers doing tests. The testing is only a few weeks, so not much to really talk about. It is essentially a giant checklist where item after item is tested and verified working correctly. When the testing is done it will be on its way to 129. A lot of it is things that cannot be seen here like solar cells, batteries, momentum wheels, thrusters, and such to verify they are working properly.
The other issue is if there is a problem discovered Dish is a public company and the material information would have to be released properly, not casually on a message board or other unofficial means. They would have to do a press release and proper SEC filings.
Maybe because they are not the owners of the satellite and not doing the testing ?
Also, to use your example, I'm sure Netflix restricts their interaction to customer issues, and not low level operational details such as you are asking for here.
The equivalent would be Netflix telling you " We ordered 10,000 copies of X-Files for Sacramento, and 7,000 for San Francisco, but now we find more demand in SF, so we had to ship 4,000 copies there, and so we had to rent two Ford Econline Vans which were made in 2004 and have 20,000 miles of them, and .... zzzz .... "
kstuart said "they are not the owners of the satellite and not doing the testing".
The contract between Dish and Ciel-2 owners is really clear that Dish has no responsibility for the testing, and if a wheel falls off this van it's the Ciel-2 owners' wheel that fell off.

Of course NORAD doesn't take the holiday's off. But maybe the guys that take their tracking information, turn it into TLEs and publish them on the internet took the holidays off. There is a difference between tracking a communications sat and an ICBM.
Dish has not hidden the location of the sat, because they never told us to begin with. If there were major problems, it would warrant an immediate SEC filing. No filing, no issues. But the fact there are signals at 138 seem to me a good indication that the sat is at 138.
NORAD doesn't vacate, but it seemed reasonable that the folks that publish the TLE's could have. I NO LONGER THINK THAT, because new TLE's were published for AMC14 this past Sunday. ODD???
More Tech Details for Ciel 2:
Payload Watts = 11041
Bus Watts = 2222
Total Load Watts = 13263
Solar Array Watts = 18451
Probability of 15 year Survival:
Payload = 0.817 (0.0 to 1.0)
Bus = 0.906
Total = 0.722
Payload Watts = 11041
Bus Watts = 2222
Total Load Watts = 13263
Solar Array Watts = 18451
Probability of 15 year Survival:
Payload = 0.817 (0.0 to 1.0)
Bus = 0.906
Total = 0.722
Don't forget that AMC-14 now belongs to the US Government so there probably is a higher priority for NORAD to generate TLEs for that spacecraft.
Thanks nelson61 for the analysis and the link. When the info. is laid out in a nice, neat chart, simple math is not needed. In looking at the "S file" I noticed from the schedule that launch was projected to begin 12-6-08 and end 12-31-08, with placement on 1-10-09.
Since the launch actually began on 12-10-08, maybe placement will happen on 1-14-09.
To answer the question "how many TPs can one spot beam serve" I eyeballed the list. The least served seemed to be 1, and the most served was 6. As previously reported, the number of "spot beams" was 53 and the number of "spots" was 145. Power at all sites appeared to be ample to support full use of all transponders.

It was on one of my forays to n2yo checking up on Ciel-2 that I first noticed AMC14 had popped up on the list. Observing AMC14 casually for a couple of days, I concluded the sat was not geostationary, but orbiting the globe.
Wrong. It seems to be nominally at 64.4E.L., but veering back and forth between about 62.2E and 65E, and also going 5 or 6 degrees above the equator and then back about the same amount below the equator. At least that's what the n2yo readings indicate. I wonder if it can actually do that without burning fuel?
So where is 64.4E? In the Indian Ocean, off the coast of...Iran, Pakistan, Somalia, etc. And now we know what AMC14 is doing.
