SSL SELECTED TO PROVIDE HIGH-POWER COMMUNICATIONS SATELLITE TO INTELSAT

PALO ALTO, Calif. – May 12, 2016 — Space Systems Loral (SSL), a leading provider of commercial satellites, today announced that it was selected to provide a high-power communications satellite for Intelsat S.A. (NYSE: I), operator of the world’s first Globalized Network, powered by its leading satellite backbone. The satellite, Intelsat 39, will provide broadband networking and video distribution services in Africa, Europe, the Middle East, and Asia. It will replace the Intelsat 902 satellite, which was also built by SSL and launched in 2001.

“SSL and Intelsat have had a close working relationship for many years,” said John Celli, president of SSL. “Intelsat 902 was part of a series of seven satellites that introduced new capabilities, which became a standard for future versions of the 1300 platform. Now, we look forward to collaborating on next-generation advances for Intelsat 39.”

Intelsat 39 will have both C-band and Ku-band transponders and will be located at the 62° East longitude position.

“Intelsat’s Globalized Network is an interoperable fleet comprised of high-throughput, spot beam and wide beam capacity, which we will continue to enhance and optimize based upon customer applications at particular orbital locations,” said Thierry Guillemin, Executive Vice President and Chief Technology Officer. “Working closely with SSL on Intelsat 39, we are incorporating the right combination of beams to support a diverse array of applications for media, government, and network services customers.”

Intelsat 39 is based on the powerful SSL 1300 platform, which has the flexibility to support a broad range of applications and technology advances, including electric propulsion. The satellite will use both electric and chemical propulsion for orbit raising and will be operated with all-electric propulsion on orbit.

Arianespace to launch Intelsat 39, dated January 4, 2017

Arianespace announced today that it will launch Intelsat 39 for Intelsat, one of the world’s largest satellite operators.

Intelsat 39 will provide broadband networking and video distribution services in Africa, Europe, the Middle East, and Asia, as well as broadband connectivity for mobile users in the Indian Ocean region. It will replace the Intelsat 902 satellite, which was launched by Arianespace in 2001.

Intelsat 39 will have both C-band and Ku-band transponders and will be located at the 62° East longitude position. Of note, Intelsat 39 was selected by the government of Myanmar to support the rollout of cellular networks beyond urban centers, essential to achieving a digitally inclusive society. Intelsat 39 is based on the SSL 1300 platform.

Arianespace will launch Intelsat 39 aboard an Ariane 5 from the Guiana Space Center, Europe’s Spaceport in Kourou, French Guiana, in the second half of 2018.

Arianespace and Intelsat: A longstanding partnership
“Arianespace has been launching Intelsat satellites since 1983, a very fruitful relationship of nearly 35 years,” said Ken Lee, Senior Vice President, Space Systems, Intelsat. “After two successful missions in 2016 that delivered the first two Intelsat EpicNG spacecraft, Intelsat 29e and Intelsat 33e, as well as Intelsat 36, into orbit, we look forward to continuing this partnership in 2017. We have the utmost confidence that Arianespace will also successfully execute the Intelsat 39 program.”

Arianespace Chairman and Chief Executive Officer Stéphane Israël said: “With 58 satellites launched for Intelsat over more than three decades, we enjoy an exceptional partnership with this leading operator. Arianespace began 2016 with a launch for Intelsat, and it is only appropriate that we start 2017 with a new launch contract with Intelsat. Thanks to Intelsat for its continuous trust: Arianespace will deliver!”

Cross-post from the VA248 thread:
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, at approximately 3500 kg.  The upper payload should be the more massive of the two, yes?

<snip>

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

Intelsat 39 is apparently the heavier of the two satellites, and would be carried on the Sylda; GSAT-30 masses at 3450 kg, and apparently will ride under the Sylda (mass reference is from my following post).

Arianespace to launch the GSAT-31 and GSAT-30 satellites for India with Ariane 5, dated September 10, 2018
Quote
The Indian Space Research Organization (ISRO) has chosen Arianespace to launch its GSAT-31 and GSAT-30 telecommunications satellites.

The two satellites are to be launched on separate Ariane 5s from the Guiana Space Center, Europe’s Spaceport in Kourou, French Guiana from end 2018 onwards, starting with GSAT-31.

Both satellites will be designed, assembled and integrated by ISRO. They are planned as replacement satellites for the currently operational satellites providing key national services in multiple frequency bands including C- and Ku Bands.

GSAT-31 will be based on an enhanced I-2K platform, to be stationed in geostationary orbit at a longitude of 48° East. It will weigh 2,500 to 2,600 kg. at launch. Providing communications to India, it will replace Insat 4CR, whose end of life is soon expected.

As for GSAT-30, it will be based on an I-3K platform, will weigh 3,450 kg. at launch and ensure continuity of service for INSAT 4A, positioned at 83° East longitude. It will provide high-quality television, telecommunications and broadcasting services.

Commenting on this contract, Arianespace CEO Stéphane Israël said: “Arianespace is delighted that ISRO has entrusted Ariane 5 with two new GEO satellites to deliver: GSAT-31 and GSAT-30, to be the 23rd and 24th ISRO satellites launched by Arianespace since our first joint success with APPLE in 1981. This contract underlines the availability of Arianespace launchers and proves to be another great demonstration of the strong bond uniting India and Europe in space cooperation for a better life on Earth.”

Ovzon Expands Reach Through Agreement with Intelsat
Wed, Apr 10, 2019 08:30 CET

Faster speeds and higher throughput to ultra-small terminals provide ground-breaking solution for mission-critical communication needs of remote users

Intelsat and Ovzon have entered into a multi-year agreement whereby Intelsat will provide service to Ovzon via two powerful steerable beams on Intelsat’s planned new satellite, Intelsat 39, expected to launch in the third quarter of 2019.  Intelsat 39 will provide services for network, video distribution and government customers in Africa, Europe, the Middle East and Asia.

The Intelsat-enabled service will add to Ovzon’s existing capacity, thereby expanding coverage for Ovzon’s customers. Combining the power, resiliency, and flexibility of Intelsat 39 with Ovzon’s managed service and ultra-small laptop-sized terminals will provide up to 5 times the throughput capability to small teams conducting disaster response, intelligence gathering, and other operations, delivering mission-critial information at the tactical edge. Such capabilities have traditionally required 2.4 meter or larger terminals.

“This agreement plays an important role in enabling Ovzon to serve customers with global requirements for high-bandwidth services. It also strengthens our partnership with Intelsat to the benefit of both companies,” said Per Wahlberg, CEO of Ovzon.

“The combination of Ovzon’s high-speed service to ultra-small terminals, Intelsat’s innovative steerable beam technology and the global coverage provided by the Intelsat fleet creates a powerful innovation in connectivity. Our partnership with Ovzon is an important step toward empowering remote users with the communications innovations they need,” added Samer Halawi, Chief Commercial Officer of Intelsat.

This information is inside information that Ovzon is obliged to make public pursuant to the EU Market Abuse Regulation. The information was submitted for publication, through the agency of the contact persons set out below, at 08.30 CET on April 10, 2019.

...Besides military satellites, Isro is also planning to launch high-profile Chandrayaan-2 mission and first demonstration test of the mini-PSLV or SSLV this year. Advanced communication satellites like Gsat-20, Gsat-30 and Gsat-32 will also be launched by early next year. Gsat-32 will replace Gsat-6A, which was lost in space after the successful launch due to a communication failure and was meant to mainly serve ground forces.

Cabinet approves Rs 3,000 crore GSLV phase-4 programme for 5 launches
Surendra Singh | TNN | Updated: Apr 15, 2019, 19:31 IST
...
A series of advanced satellites Gsat-20, Gsat-30 and Gsat-32 , which will boost communication capabilites of the country, will also be launched by early next year. While Gsat-20 and Gsat-30, a replacement of Insat-4A, will be sent to space from French Guiana, Gsat-32 will be launched from Sriharikota.

So that's a direct replacement on VA249: EDRS-C replaces GSAT-30.

EDRS-C final testing


European Space Agency, ESA
Published on Apr 27, 2019

In Ottobrunn, Germany, ESA’s laser satellite EDRS-C is undergoing final testing at Airbus before being shipped to the launch site in Kourou, French Guiana.

EDRS-C is the second node in the European Data Relay System, a unique public–private partnership between ESA and Airbus.

The system – dubbed the SpaceDataHighway by industry – provides data relay between low Earth-orbiting satellites and the EDRS nodes over optical links, with the information sent down to Europe in near-real time.

Press release, 8 May 2019

Green light for the first dedicated satellite for the European 'space data highway' - Telecommunications satellite EDRS-C ready to be transported to Kourou

The European Data Relay Satellite System (EDRS), also known as the 'space data highway', is setting a new standard in real-time data transfer. The innovative laser nodes can transport data volumes of up to 1.8 gigabits per second to Earth, with minimal
delay. The programme's first communication node, EDRS-A, was launched on 29 January 2016, and is already providing relay services for data transfer from the four Sentinel satellites of the EU Copernicus Earth observation programme. The advantage is
that the Earth observation satellites can deliver significantly more data to the ground faster and thus also better serve the end user (see info box). The first dedicated satellite in the series – EDRS-C – was designed, constructed and tested in Germany.
It has been thoroughly tested over the past 11 months and will begin its journey to Europe's spaceport in French Guiana in June 2019. It will be launched into a geostationary orbit on 24 July 2019 on board an Ariane 5 launch vehicle.

EDRS is a public-private partnership between the European Space Agency (ESA) and the primary industrial contractor, Airbus. With a programme participation of approximately 235 million euro (61 percent), Germany is the main contributor to this ESA programme.
The German Aerospace Center (Deutsches Zentrum fuer Luft- und Raumfahrt; DLR) Space Administration manages the German contributions to ESA on behalf of the Federal Government, using funds from the Federal Ministry for Economic Affairs and Energy.

EDRS-C – 'made in Germany'

The EDRS-C satellite is considered to be a milestone in the programme. It follows a first experimental laser communications terminal, launched in 2013 on the European telecommunications satellite Alphasat, as well as the operational communications
node EDRS-A. The EDRS-C satellite will be the first of its kind in the world. "With EDRS-C, the network will receive its first dedicated satellite. EDRS-C contains a lot of German high technology and follows the strategy of establishing a system provider
for telecom satellites in Germany. The German commitment thus supports systems expertise for telecommunications satellites and payloads and secures our technological lead in the field of optical communications," said Walther Pelzer, DLR Executive Board
Member responsible for the Space Administration. 

Virtually all major German aerospace locations have contributed to EDRS-C. It is the second telecommunications satellite produced by the Bremen-based company OHB and extends the SmallGEO product line of relatively low mass geostationary satellites.
The heart of the satellite is the laser terminal. The company Tesat (based in Backnang, near Stuttgart) is not only contributing the necessary technology but has overall responsibility for the EDRS communications payload. This also includes travelling
wave tubes produced by Thales in Ulm, the principal European site for radio frequency amplifier elements.

Important subsystems and components of the satellite platform also come from suppliers in Germany. For example, the chemical propulsion system was developed by Ariane Group in Lampoldshausen. Structural elements of the satellite and pressure tank were
contributed by the company MT Aerospace in Augsburg. In addition to the star tracker built by Jena Optronik and the reaction wheels produced by Collins Aerospace, other important components of the attitude and orbit control system were also ‘made in
Germany’.

The extensive satellite tests prior to launch were carried out at IABG and Airbus in Ottobrunn. Airbus in Ottobrunn already operates EDRS-A and will also take over mission control for EDRS-C after launch; it is thus able to offer a globally unique
service. The German Space Operations Center at the DLR site in Oberpfaffenhofen has been commissioned by Airbus to control the payloads and the EDRS-C satellite. DLR has invested 8.7 million euro from research funds to the development of the EDRS ground
segment and the preparations for its operation. The Bavarian State Ministry of Economics and Media, Energy and Technology provided 7.5 million euro.

EDRS-C – a European project

Despite the large German share, EDRS is a European project in which 14 ESA member states are participating. With the Earth observation programme 'Copernicus', EDRS has an important anchor customer in Europe. In addition, the optical communications
payload on EDRS-C does not require all of the resources; the satellite also hosts a payload for the British satellite operator Avanti. During the design phase of the satellite, several interested parties submitted tenders in response to a call from
ESA. Avanti, with its commercial payload 'Hylas-3', was offered the opportunity for a ride-share on EDRS-C and is therefore also bearing a proportion of the platform and launch costs.

Info box: This is how EDRS works

The principle of the European 'space data highway' becomes clear from the interaction of the Sentinel satellites of the European Earth observation programme Copernicus with EDRS. Without EDRS, Earth observation satellites in low Earth orbit can send
their data directly to Earth only when they are over a ground station. This is the case for only about 10 minutes in a satellite's 90-minute orbit. In contrast, the EDRS communications nodes remain visible to the Sentinel satellites for much longer
– for half their orbital period; that is, for about 45 minutes. Thus, with EDRS data can be sent over a longer period of time. The data are also sent directly to Europe, so that it is not necessary to rely on ground stations outside Europe. The Sentinel
satellites use this service daily, and by March 2019, well over one petabyte had already been transmitted in 20,000 satellite connections of this kind.
