SES AND ECHOSTAR TO BOOST STRATEGIC PARTNERSHIP AT 105 DEGREES WEST WITH NEW SATELLITE
Quote
Luxembourg, September 4, 2014 SES S.A. (NYSE Euronext Paris and Luxembourg Stock Exchange: SESG) announces a new cornerstone in its strategic partnership with EchoStar Corporation (NASDAQ: SATS) at the orbital position of 105 degrees West with the procurement of the new SES-11 satellite, also to be known as EchoStar 105.

SES-11 will be manufactured by Airbus Defence and Space based on the highly reliable Eurostar E3000 platform. The satellite will be launched into space in Q4 2016.

SES-11 will carry 24 Ku-band transponders as well as 24 C-band transponders (36 MHz equivalent).The spacecraft will have a separated mass of approximately 5,400 kg and an end of life budget for the payloads of approximately 12 kW.

The spacecraft's Ku-band capacity will replace the existing SES satellite AMC-15 at 105 degrees West, an orbital position where Echostar has been SES's anchor customer since 2006. The spacecraft's C-band capacity will also allow SES to provide replacement capacity for AMC-18 at 105 degrees West.

"The market for 50-state transponder capacity in North America has demonstrated significant growth for EchoStar Satellite Services over the past five years - the acquisition of EchoStar 105 renews our commitment to the fixed satellite services market in North America," EchoStar Satellite Services President Anders Johnson said. "The replacement of AMC-15, with the increased capability offered by EchoStar 105, will allow us to meet the evolving demand from our customers for enterprise, broadcast, and government services applications. We are pleased to work with Airbus Defence and Space to provide our customers with new, high power satellite capacity at this established orbital slot."

Stated Martin Halliwell, Chief Technology Officer of SES: "SES-11 is the 6th large satellite contract with our longstanding partner EchoStar. The new spacecraft will offer comprehensive coverage of the Americas, including Hawaii, Mexico, and the Caribbean, from a well-established orbital position. Together with EchoStar we look forward to a successful mission in collaboration with our reliable industry partner Airbus Defence."

I was a bit confused, because it doesn't state in the release that SpaceX will be launching this one.  But, SES's pdf overview for the S/C lists the Falcon 9 as the launch vehicle.  So, if anyone else is wondering where the official info for that was, I'm linking a copy below.

Cross posting from the Arianespace launch schedule thread:

Arianspace launch schedule shows EchoStar XX launch as TBD in 2017.  But EchoStar website (including investor documents) shows no info on EchoStar XX.  Is it known by another name?
EchoStar XX satellite became EchoStar 105 / SES-11 and switched to Falcon-9 after an agreement to share the 105 West orbital slot with a single joint satellite. EchoStar XX designation could be reused in the future since the original EchoStar XX satellite was renamed.

Launch date for this could be only two months away now, 4th in line at the cape. Should get some payload news soon.

Did SES ever confirm that this is going on a used booster?

Last we heard (during the SES-10 press conferences), they said it was going on a new booster.  The other two SES payloads this year were going to be candidates for reused boosters.

With Intelsat 35e slipping a little and August dates for CRS-12 and OTV-5, the timing of this launch could get interesting.

Announced today that SES-11 will also be launching on a used Falcon 9 rocket, likely on the F9 booster that launched CRS-10.

I wouldn't go so far as to say "announced", given that it wasn't a direct confirmation from SES or SpaceX. But Stephen Clark is a highly reliable source of info, so it's certainly very likely to be the case.

While arguably a bit optimistic, that could literally interpreted to mean October 1st, relating to the 4 day delay of CRS-12.

Your first falcon should be core 1031-2. First mission: CRS-10. Next mission: SES-11.

Too clean for previously flown, no?

The last previously flown stage never went back to McGregor but was refurbished at the Cape if I remember correctly. I would assume the same would be true for SES-11.

Your assumption makes sense, but we did have someone claiming to be an employee state that 1035.2 stopped back in McGregor a while ago. I'm having trouble finding the post (to r/SpaceXLounge), and I'm thinking it was deleted by the submitter.

So if ULA keeps their new launch date of Sept 28th, what does this mean for the NET of Sept 27th for SpaceX?

One of the key reasons I am asking is I will be in Orlando for a conference that week so the potential of 2 launches while I am there is awesome ;)

Have a look at the Manifest thread.  It's showing October now.
Excited to be finally into the first Falcon Heavy flow, we are getting so close!

Interesting that SpaceX is NET than 27th.  Guessing SpaceX is going to have to move their date since I didn't think the eastern range could recycle between launch providers in under 24 hours?
No conflict--check the most recent iteration of the US Launch Schedule thread.

SES-11/Falcon 9 launch has been delayed to early October.
