Arianespace to launch two telecom satellites for Brazil and South Korea


March 14, 2017 – For its fourth launch of the year, and the second Ariane 5 mission in 2017 from the Guiana Space Center in French Guiana, Arianespace will orbit two satellites: SGDC for VISIONA Tecnologia Espacial S.A. on behalf of the Brazilian operator Telebras S.A., and KOREASAT-7 for the South Korean operator ktsat.

 This mission, designated Flight VA236 in Arianespace’s launcher family numbering system, will be the seventh all-Thales Alenia Space mission, as both satellites were built by this manufacturer.

 The launch will be from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana.

 The Launch Readiness Review (LRR) will take place on Friday, March 17, 2017 in Kourou, to authorize the start of operations for the final countdown.


SGDC (Geostationary Satellite for Communications and Defense) is the first satellite for the operator Telebras S.A. to be launched by Arianespace, performed within the scope of a contract with SGDC prime contractor Visiona Tecnologia Espacial S.A.

 This Brazilian government program has three main objectives:
•Reduce Brazil’s digital divide by providing high-quality Internet services to 100% of the country territory as part of the National Broadband Plan
•Provide sovereign and secure means for Brazilian government and defense strategic communications
•Acquire critical technologies for the Brazilian space industry, enabling the industry to take increasingly important roles in the future Brazilian space programs.

Positioned at 75° West, with its 57 Ka- and X-band transponders, the SGDC is a multi-spot beam HTS (high-throughput satellite) capable of delivering more than 57 Gbps over the Brazilian territory.

 The SGDC will be operated and controlled by Telebras S.A., a Brazilian telecommunication company controlled by the Ministry of Science, Technology, Innovation and Communication; and the Defense Ministry.

 As SGDC prime contractor, VISIONA Tecnologia Espacial S.A. is responsible for program management, overall system integration and end-to-end communication.

 SGDC was manufactured by Thales Alenia Space in Cannes, France using the reliable Spacebus 4000C4 platform.

 KOREASAT-7 is the third KOREASAT satellite to be launched by Arianespace for ktsat, following KOREASAT-3 and KOREASAT-6, launched in September 1999 and December 2010, respectively.

 ktsat, a wholly-owned subsidiary of KT Corp. – the largest telecom/media service provider in South Korea – is the country’s sole satellite service provider. Since the establishment of the Kumsan Satellite Center (Teleport) in 1970, ktsat has been the national leader in telecommunications and broadcasting services. It currently operates three satellites.

 KOREASAT-7 will provide a full range of video and data applications, including Internet access, direct-to-home broadcasting (DTH), government communications and connectivity for VSAT (Very Small Aperture Terminal) networks.

 Positioned at 116° East, KOREASAT-7 is designed to provide higher throughput and extended coverage over Korea, the Philippines, the Indochinese Peninsula, India and Indonesia. Its added Ka-band capacity, with steerable beams, will enable it to meet increased demand.

 KOREASAT-7 was built by Thales Alenia Space in Toulouse and Cannes, France, using a Spacebus 4000B2 platform.

 For further information, download the Launch Kit by clicking here: http://www.arianespace.com/press-kits/

 To watch a live, high-speed online transmission of the launch (including commentary from the launch site in French and English), go to arianespace.com on March 21, 2017 starting 15 minutes before liftoff.

 You also can follow the launch live on your iPhone or iPad (the Arianespace HD app is free).

Payload integration underway for Arianespace’s Ariane 5 mission with the SGDC and KOREASAT-7 satellites


Maintaining Arianespace’s sustained launch pace in 2017, activity is continuing for the company’s next flight – an Ariane 5 dual-payload mission on March 21 with the SGDC and KOREASAT-7 telecommunications satellites, to be performed from the Spaceport in French Guiana.


The heavy-lift vehicle was delivered to Arianespace earlier this month by production prime contractor Airbus Safran Launchers, with the Ariane 5’s transfer from the Spaceport’s Launcher Integration Building – where it underwent the basic buildup – to the Final Assembly Building for integration of its two payloads.

In parallel, the two satellites have been progressing through their own pre-flight preparations, with both now in the Final Assembly Building. As the mission’s upper payload, SGDC was installed on Ariane 5’s SYLDA dispenser system, and then encapsulated in a long version of the launcher’s ogive-shaped payload fairing. Separately, KOREASAT-7 was integrated atop Ariane 5, to be followed by positioning of the SGDC/SYLDA/payload fairing combination atop it.

Flight VA236: Arianespace’s fourth mission in 2017

The Ariane 5 mission with SGDC and KOREASAT-7 will be Arianespace’s second flight during the month of March, and its fourth so far in 2017. Designated Flight VA236, it follows the year-opening launches of a lightweight Vega on March 6 with the Sentinel-2B Earth observation spacecraft, the February 14 mission using an Ariane 5 to orbit the SKY Brasil-1 and Telkom 3S relay satellites, and January 27’s launch of a medium-lift Soyuz to orbit the Hispasat 36W-1 telecommunications platform.

Both satellites for Flight VA236 were built by Thales Alenia Space, with the mission’s total payload lift performance set at 10,289 kg. to geostationary transfer orbit.

SGDC is the first Brazilian government satellite, as well as the initial spacecraft to be launched by Arianespace for Visiona Tecnologia Espacial S.A. – the SGDC prime contractor, responsible for the program management, overall system integration and end-to-end communication. This dual-use (civil and military) relay platform will enable the implementation of a secure satellite communications system for the Brazilian government and armed forces, while also reducing the digital divide in Brazil.

The SGDC spacecraft will be operated and controlled by Telebras, a Brazilian telecommunication company managed by the Ministry of Science, Technology, Innovation and Communication.

Spacebus platforms for Flight VA236’s two satellite payloads

Based on the Spacebus 4000C4 platform, the SGDC platform carries 57 transponders in Ka- and X-band. It will have a liftoff mass estimated at 5,735 kg., and is to be positioned at an orbital slot of 75 deg. West.

The KOREASAT-7 passenger on Flight VA236 is designed to provide improved throughput and wider coverage over Korea, Philippines, Indochina, India, and Indonesia. Equipped with Ku-band and Ka-band transponders, it will have a liftoff mass of approximately 3,680 kg. and is built on an upgraded Spacebus 4000B2 platform. The satellite’s added steerable Ka-band capacity is designed to support further demand in relay services.

Once in its orbital slot of 116 deg. East, KOREASAT-7 will be operated by KT SAT – a wholly-owned subsidiary of KT Corp., which is the largest telecom/media service provider in South Korea and the country’s sole satellite service provider.

Ariane 5 is “go” for Arianespace’s March 21 mission with SGDC and KOREASAT-7

Arianespace’s dual-payload mission to orbit telecommunications satellites for Brazil and South Korea has been given the go-ahead for a March 21 liftoff from the Spaceport in French Guiana, carrying the SGDC and KOREASAT-7 relay platforms.

The approval came at the completion of today’s Launch Readiness Review, which confirmed the “go” status of Ariane 5, its two payloads, the Spaceport launch infrastructure and the network of flight trajectory tracking stations.

This confirmation followed the completion of Ariane 5’s integration inside the Spaceport’s Final Assembly Building, performed under the responsibility of Arianespace.

For its fourth launch of the year, and the second heavy-lift Ariane 5 mission in 2017, the two passengers were built by Thales Alenia Space – marking the seventh time Arianespace has performed a dual-payload flight with both satellites built by this spacecraft manufacturer.

A 10-metric-ton payload for Ariane 5

Next week’s mission, designated Flight VA236 in Arianespace’s launcher family numbering system, is scheduled during a launch window that opens at 5:31 p.m. on Tuesday afternoon – local time in Kourou, French Guiana – and extends to 8:20 p.m. (20:31-23:20, Universal Time, UTC).

The nominal duration of Flight VA236 from liftoff to separation of the satellites is 36 minutes, 46 seconds, with Ariane 5’s total payload lift performance on this mission to geostationary transfer orbit estimated at approximately 10,289 kg.

SGDC is the mission’s upper passenger and has a liftoff mass estimated at 5,735 kg., with KOREASAT-7 installed as the lower passenger with a mass at liftoff of approximately 3,680 kg.

Spacebus 4000-series platforms for both satellite payloads

Built with Thales Alenia Space’s Spacebus 4000C4 platform, SGDC (Geostationary Satellite for Communications and Defense) is the first satellite that Arianespace is launching for Telebras S.A., performed within the framework of a contract with SGDC prime contractor VISIONA Tecnologia Espacial S.A.

Operating from an orbital position of 75 deg. West with Ka- and X-band transponders, the dual-use SGDC will provide sovereign and secure means for Brazilian government and defense strategic communications, as well as high-quality Internet services to 100 percent of the Brazilian territory as part of the National Broadband Plan.

KOREASAT-7 was produced using a Thales Alenia Space Spacebus 4000B2 platform, and will be the third KOREASAT satellite launched by Arianespace for ktsat – a wholly-owned subsidiary of KT Corp., which is the largest telecommunications/media service provider in South Korea.

Once positioned at 116 deg. East, KOREASAT-7 will provide a full range of video and data applications, including Internet access, direct-to-home broadcasting (DTH), government communications and connectivity for VSAT (Very Small Aperture Terminal) networks.  Its coverage area encompasses Korea, the Philippines, the Indochinese Peninsula, India and Indonesia.

that is the problem with a commercial spaceport. If it was a French military installation this wouldn't even occur because the military personnel don't have the constitutional authority to go on strike.

You bet. Even military-operated spaceports use a lot of contactors who can go on strike and block critical operations.

Ah. A strike. Now Kourou really feels like France

Because France has colonized French Guiana since 1503. They wanted to make that country like France since it's their territory.

Update, still a mess, roll-out today currently doubtful
Ariane5 sits nicely in BAF so no issue yet (but problems getting people inside to run checks etc.)


(and yes strikes are pretty common in Kourou...just like in France...)
