SES Selects Orbital ATK to Build SES-16/GovSat Satellite for Mid-2017 Delivery
Third GEOStar-3 Spacecraft Ordered Since 2014 Introduction


Dulles, Virginia, 16 February 2015 – Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense technologies, announced today it received a contract to build a communications satellite for LuxGovSat, a newly created joint venture between SES and the Luxembourg government. SES-16/GovSat will be used to provide military satellite bandwidth to governments and institutions. The Luxembourg government has pre-committed to a significant amount of capacity in support of its NATO obligations.

Based on Orbital ATK’s recently introduced GEOStar-3™ satellite platform, SES-16/GovSat is a multi-mission satellite using dedicated military frequencies (X-band and military Ka-band) to provide high-powered and fully steerable spot beams for multiple government-specific missions. It is Orbital ATK’s 40th GEOStar satellite sale, the third GEOStar-3 satellite purchased, and seventh GEOStar satellite to be built for SES.

“SES is one of the world’s most prominent satellite operators and this contract demonstrates a continued confidence in our GEOStar product line. As a customer-focused company known for innovation, reliability and affordability, we are pleased to provide LuxGovSat with a high-quality satellite that will meet expectations in cost, schedule and performance,” said Chris Richmond, VP and GM of the Commercial Satellite Division at Orbital ATK’s Space Systems Group. “Based on our exceptional record of delivering flight-proven satellites on time and on budget, Orbital ATK continues to be a partner that SES and the Government of Luxembourg can count on.”

Orbital ATK’s GEOStar satellite platform can accommodate all types of commercial communications payloads and is compatible with all major commercial launchers. The GEOStar design is optimized for satellite missions requiring up to eight kilowatts of payload power.

The company also offers a hybrid electric propulsion GEOStar-3 design that provides the benefits of higher power/higher payload capability while still maintaining advantageous launch costs.

Martin Halliwell, Chief Technology Officer of SES, commented, “The joint procurement of SES-16/GovSat opens a new chapter in the strategically important government business vertical and in the cooperation between SES and the Luxembourg government. SES-16/GovSat will ensure flexibility for the ever-changing missions of governments and institutions in the security, defense and civil arena and will allow for the deployment of integrated and smart end-to-end managed solutions for these demanding customers.”

SES-16/GovSat will be designed, manufactured and tested at Orbital ATK’s satellite manufacturing facility in Dulles, Virginia. It is slated for delivery in mid-2017. Once in orbit, it will be positioned on the European geostationary orbit arc with coverage areas over Europe, the Middle East and Africa. It will have a service life of 15 years.

Orbital ATK’s Space Systems Group (SSG) is an industry leader in satellite technology and advanced rated space systems providing a broad portfolio of products and services for commercial, military, civil government and international customers. The Group designs, manufactures and operates small to medium-class satellites for communication, imaging, science, human exploration and military operations. SSG also specializes in market-leading integrated thermal control systems, space components that power and enable satellites of all classes, satellite servicing technology and premier technical engineering services to government agencies and laboratories.

Another article on this , SES have 3 satellites on order max weight is 4200kg. This gives them choice of Ariane 5 or F9.

The interesting thing is that SES-16 is one of three new satellite orders from SES announced at the same time, and unlike this one the other two are fully electric-propulsion comsats. SES-14 will be built by Airbus DS on their Eurostar-3000EOR bus and SES-15 will be built by Boeing on their BSS-702SP (same bus as the twin comsats due for launch in 1.5-2 weeks time  ;)).

http://spacenews.com/airbus-boeing-and-orbital-atk-split-ses-satellite-order/

SES confirmed F9 as the launch vehicle a little afterwards.  Apparently, weight growth in Ariane upper passengers means that it is now too heavy for the lower slot.

Luxembourg-based SES, which was the first established commercial satellite fleet operator to use Falcon 9 and has another launch scheduled with SpaceX this summer, said its SES-14 and SES-16/GovSat satellites would be launched on separate Falcon 9 vehicles.

The question then will be whether SES will request an expendable F9, which in its enhanced version could deliver this to a very good orbit (1300 m/s to GEO, if they are willing to accept a VERY high apogee) or whether they will get a re-usable F9 to a more traditional orbit (1500-1600 m/s to GEO) and get a lower price for the rocket.

Well I asked them. Small chance but better then no chance.

@GovSatLu On a new or flight proven booster?

Like and retweet to increase my chances please.

SES is considering launching its next satellite — SES 16 developed in partnership with the government of Luxembourg — with a reused Falcon 9 booster in January.

Article Link

SES 16 slips to January and on a re-used booster (as I think can be expected for most SES flights from here on out).

That statement is ambiguous as to what they are "considering", a launch delay into January, use of a "flight proven" first stage, or both.

In any case, gongora's manifest currently has the SES-16 launch in January.
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

It's pretty clear in the article that SES wants to launch ASAP, so them "considering" a delay doesn't make much sense. They would only delay if the sat or the LV isn't ready.

But I think "January" and "reused booster" are related: the slip might be even further if they decide they need a new booster.  SpaceX is offering them a reused booster in January, as one package.

Another FCC app (crossposting from Reddit).

This is for mission 1389 a RTLS from SLC-40 that will launch in H1 2018. Any idea as to what this one is?

All three of the FCC applications for this flight were granted on Nov. 27 for flight from SLC-40 NET Jan. 15 with droneship landing.  I'm assuming it's GovSat-1.

SES-16/GovSat will feature a special port, which allows a hosted payload to dock with it in orbit. The port will be the support structure for an unidentified hosted payload to be launched on a future SES satellite and then released in the vicinity of SES-16. The 200 kg, 500-watt payload then will travel to SES-16 and attach itself.

Has this been confirmed as a re-used booster? Or does NASA choosing to use a re-used booster free up core b1044 for this flight?

I was convinced that B1044 was always chosen for the expendable Hispasat 30W-6 mission.

SpaceX Opens Media Accreditation for GovSat-1 Mission

HAWTHORNE, Calif. – December 22, 2017. Media accreditation is now open for SpaceX's GovSat-1 mission from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station in Florida. The launch is targeted for no earlier than late January 2018.

 

A flight-proven Falcon 9 will deliver GovSat-1 to a geostationary transfer orbit (GTO).

Is it known what booster is assigned? I'd guess CRS-12 or OTV-5, maybe KoreaSat's
