Ariane 5 | July 29, 2019
Flight VA249: Arianespace will orbit Intelsat 39 and EDRS-C with Ariane 5



For its third flight with Ariane 5 this year, Arianespace will orbit two telecommunications satellites for long-term customers: Intelsat 39, for the operator Intelsat; and the EDRS-C satellite, based on a public–private partnership between the European Space Agency (ESA) and Airbus.

Through this mission, Arianespace highlights its ability to be at the service of innovative satellite solutions for commercial and institutional needs.

Flight VA248 will be performed from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana.

The Launch Readiness Review (LRR) will take place on Friday, August 2, 2019 in Kourou to authorize the start of operations for the final countdown.

Intelsat 39 will be the 61st satellite launched by Arianespace for Intelsat since the first mission at its service in 1983. It will replace Intelsat 902 (launched by Arianespace in 2001) at 62 degrees East.

The Intelsat 39 telecommunication satellite is designed with both wide and high-powered steerable spot beams to meet the needs of broadband networking, video and government customers across Africa, Asia, Europe, the Middle East and Indian Ocean region. The steerable spot beams provide flexibility within the payload and enable customers to rapidly and efficiently respond to shifts in geographic or application requirements.

The satellite features C-and Ku-band capabilities to provide additional scale for Intelsat's Flex managed service and enhance mobile connectivity for aero, maritime and government users operating across these regions.

Intelsat 39 was built by Maxar in Palo Alto, California.

The EDRS-C satellite is the second node of the SpaceDataHighway network. The SpaceDataHighway is the world's first "optical fiber" network in the sky based on cutting-edge laser technology. It will help to improve environmental and security monitoring, disaster response and crisis management.

Launched into a geostationary orbit at 31° East, EDRS-C will be able to connect low-orbiting observation satellites via laser at a distance up to 45,000 km., as well as intelligence UAVs or mission aircraft.

The SpaceDataHighway is a public–private partnership between the European Space Agency (ESA) and Airbus, with the laser terminals developed by Tesat-Spacecom and Germany's DLR Aerospace Center. Airbus owns, operates and provides services for the SpaceDataHighway. The EDRS-C satellite platform is supplied by OHB System AG.

In addition, a hosted payload – HYLAS 3 – was provided by Avanti Communications under a contract with ESA as a customer-furnished item to OHB.

Arianespace перенесла запуск Ariane 5 с двумя спутниками на 6 августа

Ожидается, что 2 августа будет составлен отчет о готовности миссии, на его основе которого будет приниматься решение о старте или переносе

ПАРИЖ, 29 июля. /ТАСС/. Европейская ракета-носитель Ariane 5 с двумя телекоммуникационными спутниками стартует с космодрома Куру во Французской Гвиане 6 августа. Об этом сообщила в понедельник компания Arianespace. Ранее старт ракеты был запланирован на 24 июля.

"В третий за этот год полет Ariane 5 Arianespace выведет на орбиту два телекоммуникационных спутника своих давних клиентов: Intelsat 39 оператора связи Intelsat и EDRS-C, основанный на государственно-частном партнерстве Европейского космического агентства (ЕКА) и Airbus", - говорится в сообщении для прессы.

Согласно опубликованному графику, окно запуска назначено на 16:30 - 18:51 по местному времени (22:30 - 00:51 мск). Ожидается, что 2 августа будет составлен отчет о готовности миссии, на основе которого будет приниматься решение о своевременном старте или его переносе.

Ранее запуск Ariane 5 с этими спутниками, запланированный изначально на 24 июля, был отложен в связи с неудачным запуском ракеты Vega. Она должна была вывести на орбиту военный спутник Falcon Eye 1 Объединенных Арабских Эмиратов (ОАЭ), но из-за сбоя в работе двигателя второй ступени не смогла выйти на расчетную высоту и упала в Атлантический океан.

Спутник Intelsat 39 призван обеспечивать широкополосный доступ в интернет, а также передачу видеосигнала для трансляций в Африке, Европе, Азии, а также на Ближнем Востоке. Он придет на смену Intelsat 902, который был выведен на орбиту в 2001 году. Оснащенный передатчиками C- и Ku- диапазонов, он расположится на 62 градусе восточной долготы.

Аппарат EDRS-C станет вторым звеном в системе космической связи SpaceDataHighway, разработанной Airbus Defence and Space. Она подразумевает оптическую передачу данных при помощи лазерного терминала со скоростью 1,8 гигабита в секунду.

Ariane 5 | July 29, 2019
Preparations for Arianespace's next Ariane 5 mission enter the payload integration phase


The upper payload component – containing Intelsat 39 mounted on the SYLDA dispenser system, both of which are enclosed in an ogive-shaped fairing – is ready for installation atop Ariane 5.

Payload integration is underway for Arianespace's third Ariane 5 mission of 2019, which will orbit telecommunications satellites at the service of long-time customers: Intelsat 39, for global operator Intelsat; and EDRS-C, based on a public-private partnership between Airbus and the European Space Agency (ESA).

Recent activity at the Spaceport included initial steps in creating the dual-payload configuration, with Intelsat 39 riding in the upper position. This involved installing the relay platform atop Ariane 5's SYLDA dispenser system inside the launcher's Final Assembly Building.

Intelsat 39 – which was produced by Maxar Technologies – was then encapsulated by Ariane 5's protective fairing, completing the payload configuration's upper portion and readying it for positioning over EDRS-C once this spacecraft is installed atop the launcher.

Following Ariane 5's liftoff during the afternoon hours of August 6, Intelsat 39 will be released first into geostationary transfer orbit, to be followed by the separation of SYLDA – enabling EDRS-C's subsequent deployment to geostationary transfer orbit.

Ariane 5 | August 1, 2019
Launcher build-up is completed for Arianespace's dual-payload Ariane 5 flight on August 6


Final payload integration for Arianespace's Flight VA249 was performed in the Spaceport's Ariane 5 Final Assembly Building.

The Ariane 5 for Arianespace's upcoming mission from French Guiana is now fully-assembled following integration of its two satellite passengers: Intelsat 39 and EDRS-C – both of which will be delivered to geostationary transfer orbit on a flight scheduled for August 6.

Encapsulated in an ogive-shaped protective fairing, Intelsat 39 has been positioned atop its EDRS-C co-passenger – which was installed on the launcher's cryogenic core stage during previous activity inside the Spaceport's Final Assembly Building for Ariane 5.

These successive integration steps enable a new series of preparation milestones to begin. They include tomorrow's launch readiness review, which will be followed by Ariane 5's August 5 rollout to the ELA-3 launch zone.

Liftoff is scheduled during a 2-hr., 21-min. launch window that opens August 6 at 4:30 p.m. local time in French Guiana, with the two spacecraft to be deployed to orbit on a flight lasting 33 minutes.

Intelsat 39: Faster, more efficient connectivity

Built by Maxar Technologies, Intelsat 39 is designed with both wide and high-powered steerable spot beams to meet the needs of broadband networking, video and government customers across Africa, Asia, Europe, the Middle East and Indian Ocean region. The steerable spot beams provide flexibility within the payload and enable customers to rapidly and efficiently respond to shifts in geographic or application requirements.

The satellite features C-and Ku-band capabilities to provide additional scale for Intelsat's Flex managed service and enhance mobile connectivity for aero, maritime and government users operating across these regions.

Intelsat 39 will be the 61st Intelsat spacecraft launched on an Arianespace mission, continuing a partnership that extends back to 1983. The satellite will replace Intelsat 902 – lofted by Arianespace in 2011 – at an orbital position of 62 deg. East.

EDRS-C: Expanding the SpaceDataHighway

EDRS-C – based on a satellite platform supplied by OHB System – is the second node of the SpaceDataHighway, which is the world's first "optical fiber" network in the sky based on cutting-edge laser technology. Permanently fixed over a network of ground stations, the SpaceDataHighway will help improve environmental and security monitoring, disaster response and crisis management.

To be positioned at 31 deg. East, EDRS-C will be able to connect low-orbiting observation satellites via laser at a distance up to 45,000 km., as well as unmanned aerial vehicles or mission aircraft.

The SpaceDataHighway is a public–private partnership between Airbus and the European Space Agency (ESA), with the laser terminals developed by Tesat-Spacecom and Germany's DLR Aerospace Center. Airbus owns, operates and provides services for the SpaceDataHighway. EDRS-C will be the 132nd satellite launched by Arianespace at the service of Airbus, as well as its 52nd mission for ESA.

EDRS-C also carries a hosted payload – HYLAS 3 – which was provided by Avanti Communications under a contract with ESA as a customer-furnished item to OHB.
