Ariane 5 VA24X - Eutelsat 7C - 2019
« on: 12/02/2018 05:33 am »
Possibly one-half of the payload for VA248, after VA247, in first quarter 2019?

SSL SELECTED TO PROVIDE POWERFUL ALL-ELECTRIC SATELLITE TO EUTELSAT
Quote
PALO ALTO, Calif. – March 21, 2016 — Space Systems Loral (SSL), a leading provider of commercial satellites, today announced that it was selected to provide a high power all-electric satellite to Eutelsat, one of the world’s leading satellite operators. The satellite will principally provide broadcast services to multiple regions including Africa, the Middle East, and Turkey.

“Following the successful launch of EUTELSAT 65 West A earlier this month, we look forward to continued collaboration with the Eutelsat team,” said John Celli, president of SSL. “The EUTELSAT 7C spacecraft has advanced capabilities that demonstrate the flexibility and power of the SSL satellite platform.”

EUTELSAT 7C is an all Ku-band satellite equipped with 44 operational transponders to provide service from 7 degrees East longitude. It is also designed with a steerable beam for flexible coverage.

“EUTELSAT 7C will help us meet ongoing demand for broadcast content delivery in a fast-growing communications environment,” said Rodolphe Belmer, chief executive officer of Eutelsat. “SSL has proven a valued and customer-driven manufacturing partner and we are very pleased to continue working together on advanced satellite technologies.”

EUTELSAT 7C is based on the SSL 1300 platform, which has the flexibility to support a broad range of applications and technology advances.  It will exclusively use electric propulsion for orbit raising as well as station keeping and will provide service for a minimum of 15 years.

All-electric satellites provide efficient solutions for satellite operators by reducing launch mass while retaining payload performance. SSL’s all-electric satellites are derived from SSL’s extensive electric propulsion heritage that includes 19 satellites launched with electric propulsion since 2004 representing 53,000 hours of on-orbit thruster operation.

Eutelsat signs new launch contract with Arianespace, dated June 2, 2017

With this latest contract, Arianespace now has three further satellites to launch for Eutelsat

Following the launch earlier today of the EUTELSAT 172B satellite, Eutelsat Communications (NYSE Euronext Paris: ETL) announces a new launch services contract with Arianespace.

The Arianespace order book now includes three future launches for Eutelsat in addition to the 32 Eutelsat satellites already launched by the European launch services provider over more than 30 years for one of the world’s leading satellite operators.

Of the three satellites to be launched, EUTELSAT 7C (built by SSL) will be orbited in 2018, followed in 2019 by Eutelsat Quantum built by Airbus and the high throughput satellite built by Thales.

Commenting on this latest contract, Rodolphe Belmer, Chief Executive Officer of Eutelsat, said: “Following today’s historic Ariane launch of Europe’s first high-power all-electric satellite, we are proud to once again team up with Arianespace, a long-standing partner and a leader in Europe’s vibrant space industry. The technological diversity of the three new satellites entrusted to Arianespace is a compelling reflection of our commitment to innovation for the greater benefit of our customers, and to maintaining our competitiveness.”

Stéphane Israël, Chief Executive Officer of Arianespace, added: “This latest contract bolsters Eutelsat’s position as a benchmark customer of Europe’s heavy launcher, since Ariane 5 will launch three satellites for the European operator in 2018 and 2019. Our hope is that Ariane 6 will subsequently take over so that we can help Eutelsat meet its objectives even more efficiently.”

Ordered from Space Systems Loral, and launching third quarter 2018, EUTELSAT 7C will be equipped with 44 operational Ku-band transponders.

The new satellite will be copositioned with EUTELSAT 7B, releasing EUTELSAT 7A to another orbital location. This improved two-satellite constellation with enhanced coverage flexibility and connectivity will take the 7° East neighbourhood to a new level.

By almost doubling capacity over Sub-Saharan Africa, from 22 to 42 transponders, EUTELSAT 7C will have room for several hundred additional digital channels to support the region’s fast expanding TV market. It will also be equipped with a beam providing enhanced capacity for government services over Europe, the Middle East and Central Asia, as well as a steerable beam that can cover any region visible from 7° East.

Eutelsat also writes Q1 / 2019 for the Eutelsat 7C launch in the current quarterly report.
https://www.eutelsat.com/files/contributed/investors/pdf/FY1819/Eutelsat_Communications_Q1_2018-19_Presentation.pdf

Eutelsat-7C fits in the lower position of the Ariane 5.
http://epic-src.eu/wp-content/uploads/13_EPICWorkshop2017_EUTELSAT_EPIC_2017_Madrid_FINAL.pdf

But I see in Q1 2019 no launch slot for VA-248 and also no partner for the upper position.
A potential partner: Intelsat-39 is still planned in Q2 / 2019.
IS-39 has a hybrid orbit raising system similar to IS-38. I did not find the mass and dimensions.
So I do not know if he should start over or under the Sylda.

A new animation about Eutelsat-7C.



Satellite mass 3.5 t.

EUTELSAT 7C is a new high-power broadcast satellite for fast-growing video and data markets in Africa, Europe, the Middle East and Turkey. Launching in 2019, it will be located at 7° East, one of Eutelsat’s fastest-growing video neighbourhoods.
no exact launch window  :-\

I don't see any remaining room in the launch schedule for a "VA248" launch in Q1 2019.

We've been told it takes approximately 2 weeks between successive launches at Kourou.

Given the current schedule, there's no room to squeeze in another launch before April 1.

VA247 launches on February 5.

VS21 launches on February 19, 14 days after VA247.

VV14 launches on March 9 UTC, 18 days after VS21.

VS22 launches on March 26, 17 days after VV14.

Adding another fourteen days, one arrives at April 9.  That would be the approximate NET date for the following launch, assuming all happens as currently scheduled.

Planned launches:
Date - Satellite(s) - Rocket - Launch Site - Time (UTC)

2019
January 23  February 5 - HS4-SGS1 (Hellas-Sat-4, SaudiGeoSat-1), GSAT-31 - Ariane 5 ECA (VA247) - Kourou ELA-3 ~20:00
Late   February 19 - OneWeb (x6) - Soyuz-ST-B/Fregat-MT (VS21) - Kourou ELS ~21:30
Early   March 9 - PRISMA (Precursore Iperspettrale della Missione Applicativa) - Vega (VV14) - Kourou ZLV - 01:50:35
March 26    April   - O3b FM17, O3b FM18, O3b FM19, O3b FM20 (Block 3b) - Soyuz-ST-B/Fregat-MT (VS22) - Kourou ELS
Q2 - Falcon Eye 1 - Vega (VV15) - Kourou ZLV
Q1  Q2 - Eutelsat 7C - Ariane 5 ECA - Kourou ELA-3
Q2 - Intelsat 39 - Ariane 5 ECA - Kourou ELA-3
May - EDRS-C (Hylas 3) - Ariane 5 ECA - Kourou ELA-3
NET May - GSAT-30 - Ariane 5 ECA - Kourou ELA-3

Changes on December 29th
Changes on January 5th
Changes on January 10th

As to Eutelsat 7C's launch partner:
<snip>
Eutelsat-7C fits in the lower position of the Ariane 5.
http://epic-src.eu/wp-content/uploads/13_EPICWorkshop2017_EUTELSAT_EPIC_2017_Madrid_FINAL.pdf

But I see in Q1 2019 no launch slot for VA-248 and also no partner for the upper position.
A potential partner: Intelsat-39 is still planned in Q2 / 2019.
IS-39 has a hybrid orbit raising system similar to IS-38. I did not find the mass and dimensions.
So I do not know if he should start over or under the Sylda.

Waiting for a complementary payload, available in 2019 Q2, is no longer a problem.

The lower mass satellite's place is under the Sylda, in this case Eutelsat 7C.  The upper payload should be the more massive of the two, yes?

EDRS-C is likely to be a "lower mass" payload, too, as it is built on OHB's Small GEO bus.
https://space.skyrocket.de/doc_sdat/edrs-c.htm
https://space.skyrocket.de/doc_sat/ohb_luxor.htm

GSAT-30 is listed as massing 3100 kg; also a "lower mass" payload.
https://space.skyrocket.de/doc_sdat/gsat-30.htm

The remaining possibility is Intelsat 39.
https://space.skyrocket.de/doc_sdat/intelsat-39.htm
Its fellows, built on SSL-1300S buses, mass between slightly less than 5000 kg to over 7000 kg.
https://space.skyrocket.de/doc_sat/ssloral-1300.htm
If Intelsat 39 is built as one of these larger and more massive s/c, then I deduce that it will be the launch partner for Eutelsat 7C.

All bets are off if the current payload availabilities are changed by months.
