I believe it is supposed to be a spot beam satellite with steerable spot beams (i.e. they can move the satellite to a different slot and points the spot beams as needed). I suspect it would replace E7. They could then cover more cities since E7 is pretty inefficent when compared to E10. It would allow them to have some backup of spots. If they lose E7 right now they would have a big problem.
Theres a whole heap of guessing going on here guys ;0 Yes it will replace an existing satellite. 119 (Echo 7) is NOT a likely candidate when you think about it. That satellite is the most healthy of the fleet currently. (Read the release on the health of the whole fleet somewhere on this site) A more likely candidate would be another mainsteam conus bird that is semi failing/troubled and not being replaced by something else already (that rules out Ciel2) ;0

Echostar 11 & 129
Echostar 11 is post to be launched in 07 sometime and I wonder if they will use it to replace the 129.. They are both SSL-1300 birds but the E* 11 will be newer.

Echostar 11
Space Systems/Loral (SS/L) announced in December 2004 that it has been selected by EchoStar Communications Corporation, Englewood, Colo., to build EchoStar XI, a new direct broadcast satellite (DBS) based on SS/Ls LS-1300 platform that will support EchoStars DISH Network and serve as backup to its existing fleet.
EchoStar XI, anticipated to be delivered in early 2007, will be the fifth SS/L-built satellite in the EchoStar fleet.

Echostar 5, 6 / Ciel 1
EchoStar V and VI are series of 2 high-powered direct broadcast satellites (DBS) being built by Space Systems/Loral (SS/L) for EchoStar Communications Corporation.
The power and range of EchoStar V and VI allow EchoStar's DISH Network customers to receive hundreds of television channels of programming. EchoStar's current fleet of six satellites has the capacity to offer 500 channels of content that include digital video and audio, local network programming, Interactive TV and high-speed data services, business television, and other niche services.
EchoStar V and VI have each 32 transponders operating at 125 watts, switchable to 16 transponders operating at 250 watts. Total satellite power will be in autumnal equinox at 10,000 dc watts, making them the most powerful direct broadcast satellite ever manufactured. They are expected to provide more than 12 years of uninterrupted service.
The EchoStar spacecraft is based on SS/L's three-axis, body-stabilized LS-1300 bus, whose modular design is flight-proven and has an excellent record of reliable operation.
Echostar 5 and 6 were originally ordered by MCI as Sky 1A and 1B (or MCI 1 and 2).
In July 2001, Echostar 5 experienced the loss of one of its three momentum wheels. Two momentum wheels are utilized during normal operations and a spare wheel was switched in at the time. A second momentum wheel experienced an anomaly in December 2003 and was switched out resulting in operation of the spacecraft in a modified mode utilizing thrusters to maintain spacecraft pointing. While this operating mode provides adequate performance, it results in an increase in fuel usage and a corresponding reduction of spacecraft life. This operating mode is not expected to reduce the estimated design life of the satellite to less than 12 years. During August 2001, one of the thrusters on Echostar 5 experienced an anomalous event resulting in a temporary interruption of service. The satellite was quickly restored to normal operations mode. The satellite is equipped with number of backup thrusters. In March 2005, the satellite was leased to Ciel Satellite Communications of Canada and moved to 129°W.
Echostar 6 suffered a partial thruster failure in 2001, leading to a performance loss.

1300 Series Satellite Platform
--------------------------------------------------------------------------------
The 1300, an industry leader in power, performance, and reliability, is a space-proven platform for a wide range of satellite services. The 1300 was first introduced in the mid-1980s and has been in constant evolutionary development to deliver increasingly higher power, greater flexibility, and longer mission life, keeping SS/L in the forefront of satellite technology.
The versatile 1300 series has a total satellite power capability ranging from 5 to 25 kW continuously throughout the life of the spacecraft, and can support from as few as 12 active transponders to as many as 150 transponders.
SS/L's 1300 features a lightweight and high-strength structure, fuel-efficient attitude and stationkeeping subsystems, high efficiency and reliable solar arrays and batteries, and advanced command and control subsystems.
SS/L manufactures the 1300 in our state-of-art facility in Palo Alto, California. Integration of components into payload and bus subsystems, as well as satellite system level testing, are all performed in this location with highly efficient and well-established processes. This centralized production philosophy coupled with colocated subsystem and systems engineering resources enables SS/L to deliver reliable satellites on a dependable schedule.

Ciel is required to get there own bird up at 129, a lease or borrowed bird will not satisfy the requirement.
Dish could put it up at 119, and move E7 somewhere as a backup.
Of course, if 4.5 spacing comes about, Dish could always squeeze E11 at 114.5

Does anyone else think that if 4.5 spacing ever does happen there will be a rash of service visits to re-point substandard dish installations that will start to get interference?
Dish is in dire need right now of backup satellites. The only backup they have now is E6 sitting dark at 110. If E8 were to go out, E6 could be use, but E6 was built before the concept of spot beams, and does not like to share frequencies with other satellites. Turning on E6 would cut the capacity of E10 down dramatically.
If E7 were to go out they would have all of 119 go out until E6 could be moved over there. Of course then they would not have any spots at 119, another disaster.
If E3 goes out they lose most of 61.5, not as big of a disaster, just the NE would be really hurt since the problem of looking at 129 from the NE. If E12 (old R1) goes out E3 could cover most of it, but would lose some capacity.
If E1/2 go out it would not hurt too much since 148's role has been cut way back with the introduction of 129.
If E5 were to go out they would lose 129 until they move E6 over to there. They may be able to get some coverage from 148 but all the new customers do not have a dish pointing at 148 for HD.
E11 being a backup for E7/E8/E10 really helps the emergency contingencies. Yes it could be used for a tweener slot or a 129 backup, but more likely E6 would move to 129 if E5 failed. A new satellite is already being built for 129.
Dish really has a problem, satellites can fail at any moment, and they are very limited right now with what they can do. They had a bad run of satellites for a while E3 with over heating, E4 with no power, E5 with lost momentum wheels.
Dish also needs to get a replacement up for E3.
Right now a E10/E8/E7 satellite failure would set Dish back years. Imagine how many subs they would lose without local channels. It would be a devistating blow to the company. E11 is critical.

I wonder how they are going to test to see if there would be interference or not. Some areas might get affected more than others too with the interference. By the time they would approve 4.5 degree spacing satellite might be out of business or getting really down on sub numbers when it is needed now.
If the rumors are true that E-11 has steerable spotbeam capability, then it would make the most sense to make it capable for use at both 119 W and 129 W. Barring a major failure of E-7 at 119 W, Dish should try to launch E-11 to 129 W in early 2007 and use it to provide a large number of HD locals until the Ciel-2 satellite is launched in late 2008 to 129 W. The steerable spotbeam capability gives Dish a good argument for using E-11 at 129 W temporarily. Once Ciel-2 is launched, E-11 moves to 119 W and replaces at least the spotbeam capabilities of E-7. If E-7 were to have a major failure while E-11 is at 129 W, it would only take Dish a few days to move it to 119 W with FCC approval.
As a side note related to satellites, Dish has leased all of AMC-14, a DBS satellite being built by SES Americom. Dish has asked SES Americom to modify AMC-14 so it can be used at 77 W at least temporarily. This may imply that AMC-14 will have steerable capability but to my knowledge, it is not a spotbeam satellite. This modification of AMC-14 pushes its launch date back to late 2007.
In regards to the 4.5 degree spacing, what I have heard is that the FCC is considering allowing/licensing reverse DBS frequencies i.e., the frequencies used for uplinking to a DBS satellite are used for downlinking and vice versa.

That's an interesting idea, if true.rocatman said:
I can see a lot of up-link problems associated with that approach, but not unsolvable.
More interesting, is that end-user LNBs would need to be different for those frequencies.
That just opens up a whole new can of worms.
As if the existing queer (combo) LNBs weren't bad enough.

There's this new thing, call satellites. they orbit the earth, sort of like how the moon does. And the moon is that big white/grayish thing you see glowing at night. Glowing is when something reflects off the light that is hitting it, in this case the sun. The sun is what provides us light and heat. Anyways back to satellites. There not just for NASA or the Goverment or those scifi freaks anymore! they can actualy provide you 100% digital-quality tv at you home, all on the dish the size of a trash can lid, in most cases. Digital, is used to define the difrence in quality between analog, traditional tv pq that you can get with "rabbit ears" or your local basic cable package.
Sorry, couldent resist the urge.........

makes one almost want to take aim with a gun and shoot it down, then maybe e* will get off their ass and speed up replacing their fleet
E* does not have license for any "Tweener" slot. They do have a lease for AMC-14 which was originally scheduled to go to 105.5, but until the "Tweener" authorization happens it will not be usable for service to the USA.
The reverse polarity thingy is no significant hurdle. The receivers would have to be programmed for the satellites anyway.

He was talking about using uplink frequencies for downlink. That's different from what you're saying. The uplink frequencies are way higher than 12.5 GHz, at 17.3 to 17.8 GHz--that's Ka-band and cannot be received by any consumer equipment that Echostar has currently deployed, requiring new LNBs, receivers, but on the bright side smaller dishes.
New LNBFs, yes. New receivers would depend on the bandwidth of the transponders. If they are ultrawide, could be quite expensive and very unreliable. Smaller dishes. The fantasy 13 inchers of the past?
