ЦитироватьFirst Spacebus Neo satellite set for launch
13/01/2020

The first satellite developed under an initiative to help European industry deliver competitive satellites for the commercial telecommunications market has entered its final phase before launch.

Konnect will provide broadband services for Europe and Africa, and was built by Thales Alenia Space for Eutelsat, its commercial operator, under an ESA Partnership Project.

After a long flight on board an Antonov cargo plane from Nice airport in France, the satellite was delivered to the launch site in French Guiana inside its large transport container.

The satellite has completed its short and efficient launch campaign. Teams at the launch site have conducted all tests and inspections, and confirmed that sub-systems are flight ready.

The satellite is placed within the fairing

The satellite was placed on the upper position of the secondary payload adapter and then within the fairing. These assembled parts have now been fitted on top of the launcher, during the last major step of the mechanical integration of the Ariane 5 rocket.

The satellite is now ready to be launched on 16 January, for the first Ariane launch of 2020, flight VA251.

After the launch of Konnect, the Spacebus Neo programme will continue to introduce further innovative technologies to the next satellites to be launched.

So far Thales Alenia Space has sold seven Spacebus Neo satellites. The next six missions will be: the French government's Syracuse-4; SES-17; another two Eutelsat missions called Konnect Very High Throughput Satellite and Eutelsat 10B, which will provide connectivity services for aviation and maritime transport; Satria, which will be operated by the Indonesian operator Pasifik Satelit Nusantara; and Amazonas Nexus for Hispasat, a Spanish operator, which will deliver high-capacity mobility services for aviation and maritime transport.

The Spacebus Neo product line is developed in the frame of ESA's programme of Advanced Research in Telecommunications Systems (ARTES) and the French PIA ("Programme d'Investissement d'Avenir"), in cooperation with ESA Member States, and managed jointly by ESA and the French Space Agency, CNES.

It has generated an exceptional return on investment to European industry and ESA Member States.

The Neosat programme comprises both Spacebus Neo by Thales Alenia Space and Eurostar Neo by Airbus. It includes development and in-orbit validation of the new satellite product lines for both companies, allowing the two European satellite prime integrators to deliver competitive satellites for the commercial market.

ЦитироватьAriane 5 | January 14, 2020
Ariane 5 is cleared for Arianespace's year-opening launch with EUTELSAT KONNECT and GSAT-30

Arianespace's first mission of 2020 has been authorized for liftoff fr om the Spaceport in French Guiana, with this "green light" provided at the conclusion of today's launch readiness review for an Ariane 5 flight with two telecommunications satellite passengers.


Flight VA251's "upper composite" – composed of EUTELSAT KONNECT, the SYLDA dispenser system and Ariane 5's protective payload fairing – is lowered over GSAT-30 to complete launcher build-up.

The approval follows integration of Ariane 5's dual payload, which was completed inside the Spaceport's launch vehicle Final Assembly Building.

Liftoff of the year-opening mission – designated Flight VA251 in Arianespace's numbering system – is set for January 16 during a launch window that opens at 6:05 p.m. local time in French Guiana. The two passengers are to be deployed into geostationary transfer orbit during a mission lasting approximately 38 minutes.

Today's authorization clears Ariane 5 for its roll-out tomorrow from the Spaceport's Final Assembly Building to the ELA-3 launch zone, wh ere it will be readied for Thursday's liftoff.

Another dual-passenger deployment for Ariane 5

Encapsulated in the protective fairing, EUTELSAT KONNECT is mated atop Ariane 5's SYLDA dual-payload dispenser system and positioned as the launch vehicle's upper passenger. To be deployed first during the flight sequence, it is a new-generation high-throughput satellite that will deliver services across Europe and Africa.

Produced by Thales Alenia Space, EUTELSAT KONNECT is the first to use the company's Spacebus NEO platform developed under the Neosat Partnership Project conducted by the European and French space agencies (ESA and CNES). The spacecraft will weigh approximately 3,620 kg. at liftoff and is to operate from an orbital slot at 13 deg. East.

Located below EUTELSAT KONNECT in the launcher payload configuration is the lower passenger, GSAT-30, installed atop the heavy-lift vehicle's core stage.

Produced by the Indian Space Research Organization (ISRO) using an I-3K platform, GSAT-30 is to provide high-quality television, telecommunications and broadcasting services. It has a calculated liftoff mass of 3,357 kg. and is to ensure continuity of service for India's INSAT 4A, positioned at 83 deg. East longitude.

The overall lift performance for Ariane 5 on Flight VA251 is estimated at 7,888 kg. – which includes the mass of its two satellite passengers and the payload integration hardware.

Ariane 5 reaches the launch zone for tomorrow's dual-satellite mission

Arianespace has delivered another Ariane 5 to the launch zone at Europe's Spaceport in French Guiana, positioning the vehicle for liftoff on January 16 with two satellite passengers on board: EUTELSAT KONNECT and GSAT-30.


The Ariane 5 nears completion of its transfer fr om the Final Assembly Building to the ELA-3 launch zone.

Riding atop a mobile launch table, Ariane 5 was transferred to the ELA-3 launch zone from the Spaceport's Final Assembly Building – wh ere its two passengers had been integrated as part of pre-flight preparations.

With the rollout completed, the final countdown will begin for Thursday's liftoff at the start of a 1-hour, 55-minute launch window scheduled to open at 6:05 p.m. local time in French Guiana.

Sending satellites to GTO

For this 251st launch of an Ariane-series vehicle – designated Flight VA251 in Arianespace's numbering system – the payload lift performance to geostationary transfer orbit (GTO) is approximately 7,888 kg. This combined total factors in EUTELSAT KONNECT and GSAT-30, plus the dual-passenger dispenser system and satellite integration hardware.

EUTELSAT KONNECT – which was produced by Thales Alenia Space for Eutelsat – is riding in the upper position of Ariane 5's payload arrangement, to be released first in the flight sequence at 27 minutes following liftoff.

GSAT-30 was designed and manufactured by the Indian Space Research Organization (ISRO), and will be deployed from Ariane 5's lower passenger position 38 minutes into the flight – completing the mission.

ЦитироватьNew European satellite design to debut on Ariane 5 launch Thursday
January 16, 2020 | Stephen Clark

A broadband communications satellite for Paris-based Eutelsat — built on a new Thales Alenia Space all-electric design with xenon plasma thrusters — and an Indian broadcasting spacecraft are fastened to the top of an Ariane 5 launcher for liftoff Thursday fr om French Guiana.

Liftoff is scheduled during a launch window opening at 4:05 p.m. EST (2105 GMT) and closing at 6 p.m. EST (2300 GMT) Thursday.

The mission will mark the 107th flight of an Ariane 5 rocket since 1996, and the 251st flight of a launcher in the European Ariane family since 1979. It will be the first of up to 22 launches this year for Arianespace, the French launch services provider, using Ariane 5, Soyuz and Vega boosters from launch sites in French Guiana, Kazakhstan and Russia.

After lifting off from the tropical space base on the northeastern coast of South America Thursday, the Ariane 5 will deliver the Eutelsat Konnect and GSAT 30 satellites to an elliptical geostationary transfer orbit ranging between 155 miles (250 kilometers) and 22,220 miles (35,761 kilometers), with an orbit tilted 6 degrees to the equator.

Separation of the two satellites from the Ariane 5 launcher's upper stage is planned around a half-hour after liftoff.

Each satellite will use its own propulsion to circularize its orbit at geostationary altitude more than 22,000 miles over the equator, wh ere their velocities will match the rate of Earth's rotation, giving each spacecraft a fixed geographic coverage zone.

The Eutelsat Konnect satellite is the largest of the two payloads on Thursday's mission.

Built by Thales Alenia Space, the Eutelsat Konnect spacecraft will provide broadband connectivity over Europe and Africa during a mission slated to last at least 15 years.

Eutelsat Konnect is the first spacecraft built on the new Spacebus Neo satellite bus, which was developed by Thales with funding from the European Space Agency and the French government, including the French space agency, CNES.

"Creating Spacebus Neo, a completely new product line, and in parallel meeting the schedule of the first satellite Konnect has been quite a challenge, which Thales Alenia Space and its consortium have brilliantly mastered," said Magali Vaissiere, director of ESA's telecommunications programs.

"This has only been possible through the successful cooperation between Thales Alenia Space and the agencies ESA and CNES, who have co-managed this project, the excellent coordination with Eutelsat, and the continued support of our European member states.

ESA helped fund development through the space agency's Neosat program, which aims to develop new European satellite designs with reduced cost and increased capabilities, ensuring Europe's large satellite manufacturing base remains competitive in the global market.

ESA's Neosat program supported the development of new satellite platforms by Thales and Airbus Defense and Space. Eutelsat, the largest commercial European satellite operator, agreed to be the first customer for both of the new satellite designs.

The Thales Spacebus Neo satellite platform will debut with Thursday's launch, and the Airbus Eurostar Neo platform will launch for the first time in 2021.

The Spacebus Neo platform features an all-electric propulsion system with xenon-fueled ion thrusters to perform all the satellite's post-launch maneuvers.

The low-thrust, high-efficiency xenon jets mean it will take several months for the Eutelsat Konnect satellite to reach its final operating station in geostationary orbit, but the all-electric propulsion system comes with major benefits.

"Eutelsat Konnect is the first satellite to use the Spacebus Neo electric propulsion platform from Thales Alenia Space," said Peter Newell, Eutelsat Konnect's program manager at Eutelsat. "Satellites using electric propulsion provide effective solutions for satellite operators, allowing them to maximize the payload capability of the satellite while maintaining a low overall spacecraft mass.

"As the first of its kind, there have many challenges during the development, qualification, manufacturing and test phases, but thanks to the skill and expertise of the Thales, Eutelsat and ESA/CNES teams, the satellite has been brought conception to today's launch in just four years, which is a great achievement."

The Eutelsat Konnect spacecraft, which rides in the upper position of the Ariane 5 launcher's payload bay, weighs 7,978 pounds (3,619 kilograms) at liftoff, significantly less than a similarly-capable communications satellite that used conventional chemical hydrazine fuel.

The Spacebus Neo satellite platform joins other all-electric geostationary satellite buses currently flying from other satellite manufactures, including Boeing, Maxar and Northrop Grumman.

The xenon propulsion package was developed by Thales teams in the United Kingdom, and the payload module comes from a facility in Toulouse, France. Final assembly of the Eutelsat Konnect satellite occurred at a Thales site in Cannes, France.

Eutelsat Konnect is expected to enter commercial service this fall after the slow, multi-month orbit-raising campaign.

The high-power satellite hosts a Ka-band communications payload with a total capacity of 75 gigabits per second, providing Internet services for individuals and companies in Europe and Africa. Eutelsat Konnect will also link with public WiFi hotspots in Africa to provide Internet service to mobile phones and other devices.

"Thanks to its 92 user beams with four deployable antennas, the satellite provides coverage to 15 countries in Europe and 45 countries in Africa," Newell said. "In bringing broadband Internet to Africa and Europe with state-of the-art satellite telecommunication technology, Eutelsat Konnect will make a major contribution in bridging the digital divide.

"Initially, Eutelsat Konnect will operate in both Europe and Africa combined, but thanks to the high flexibility... it will be possible in the future to reallocate all of the satellite capacity to the African market," Newell said.

After releasing the Eutelsat Konnect spacecraft, the Ariane 5's upper stage will re-orient itself for separation of GSAT 30, the smaller of the two payloads on Thursday's launch.

The 7,400-pound (3,357-kilogram) GSAT 30 spacecraft, built and operated by the Indian Space Research Organization, will replace the aging Insat 4A spacecraft, which launched in 2005 on a previous Ariane 5 mission.

GSAT 30 will operate from a position in geostationary orbit at 83 degrees east longitude over the equator.

"GSAT 30 will provide continuity of direct-to-home TV services from this slot, as well as digital satellite news-gathering and very small aperture terminal services," said K. Sivan, ISRO's chairmen. "The Ku-band transponders will provide services over the Indian mainland and islands.

"The satellite employs high-power amplifier and state-of-the-art antenna systems to meet the requirements of multiple users," Sivan said.

"The GSAT 30 communications payload is equipped with 12 C-band transponder and 12 Ku-band trapsonders," said D.K. Das, director of ISRO's Satellite Applications Center. "The C-band transponders are designed for two-way communications using VSAT terminals over a vast geographic region extending up to Australia in the east and Europe in the west."
