Special delivery: payloads arrive for Arianespace’s fifth Soyuz mission carrying O3b satellites

The latest batch of O3b satellites for launch by Arianespace are unloaded from a chartered IL-76 cargo aircraft at French Guiana’s Félix Eboué Airport. They will be orbited by a medium-lift Soyuz on Flight VS22.

French Guiana has welcomed the four passengers for Arianespace’s second Soyuz mission in 2019, which will further expand the SES-owned O3b satellite constellation delivering low-latency, fiber-like connectivity to customers in more than 40 countries.

This spacecraft quartet – built by Thales Alenia Space – arrived this week aboard a chartered cargo jetliner that landed at Félix Eboué Airport near the capital city of Cayenne, enabling them to be transferred by road to the Spaceport’s preparation facilities.

The O3b fleet of medium-Earth orbit (MEO) satellites is a proven non-geostationary constellation that provides commercial broadband services today, delivering carrier-grade services. The first 16 spacecraft for O3b were successfully orbited by four Soyuz vehicles operating from the Guiana Space Center in 2013, 2014 and 2018. Each satellite weighs about 700 kg. at launch and provides more than 10 Gbps of capacity.
“From 16 to 20” with Arianespace Flight VS22

By increasing the size of the O3b constellation from 16 to 20 satellites, SES Networks will offer enhanced coverage while providing greater service availability and reliability – responding to increasing demand for bandwidth from governments, as well as the telecom, cloud, maritime and energy markets.

This upcoming Soyuz mission is designated Flight VS22 in Arianespace’s launcher family numbering system, signifying the medium-lift workhorse’s 22nd liftoff from the Spaceport since its 2011 introduction at French Guiana.

4 latest O3b satellites arrive at launch base

February 7, 2019 – The four latest O3b satellites arrived at the Guiana Space Center in French Guiana on February 2, after being shipped from Thales Alenia Space’s facility in Rome. Built by Thales Alenia Space as prime contractor for SES, these communications satellites will be launched by a Soyuz rocket in March 2019, joining the current constellation of 16 satellites. The O3b system has been operational in orbit since 2014.

With the four latest satellites up and running in medium Earth orbit (MEO), the O3b constellation will offer greater capacity, better coverage and more efficient operation, along with higher reliability. SES Networks, SES’ provider of global managed data services, will call on these high-performance satellites to offer communications services to telecommunications, maritime, aeronautical, and energy markets, as well as governments and institutions across the world.

These Ka-band satellites are positioned at an altitude of 8,000 kilometers along the equator, providing low-latency, fibre-like connectivity.

As prime contractor for a total of 125 satellites in three constellations, Globalstar 2 (24), O3b (20) and Iridium® NEXT (81), Thales Alenia Space is clearly the benchmark partner in the development and deployment of low and medium orbit telecom satellite constellations.
