On Thursday, July 10, 2014 at 3:55 pm local time in French Guiana, Arianespace successfully performed its second launch for O3b Networks, following the successful launch of the operator's first four satellites last year.With this eighth Soyuz launch from the Guiana Space Center, all successful, Arianespace proves its long-term support for new operators and helps reduce the world's digital divide. The O3b mission will provide low-cost, high-speed Internet access to the “other 3 billion” people on Earth.Arianespace lofted four more satellites in the O3b constellation ("Other 3 billion") into an equatorial orbit. Built by Thales Alenia Space as prime contractor, these four satellites will enable O3b Networks to supply broadband Internet access at moderate prices to emerging markets in Asia, Africa, Latin America, Australia and the Middle East, totaling nearly 150 countries surrounding the equator where broadband access is rarely available. Following this launch, the O3b constellation will be deployed in its initial configuration and will be fully operational.GTD AT KOUROU SPACE CENTEREach time an Ariane 5, a Soyuz or a VEGA are launched from the spaceport in Guiana, as well as the payload, many hours of work are required from GTD’s technical teams.GTD supplies services and software in practically all steps of an Ariane 5 mission – from the launcher's flight program to the responsibility of ground systems that control the launching operations, as well as the radars, telemetry and mission control systems.Each launch is also a challenge for GTD’s team, who is responsible for all the computer systems at the launch site. Each launch is a fresh new project; there is no routine, which means our engineers always embark on an adventure than goes beyond technical jobs that require a lot of responsibility.Countdown: The campaign to prepare a launcher takes about 22 - 30 working days, and a campaign to prepare the payload (satellite) takes from 4 weeks to 5 months (depending on the mission and its magnitude). Our teams are currently able to launch up to seven double Ariane 5, up to four soyuz and up to two Vega per year, that is, 14 telecom satellites and 4 to 6 EO and scientific spacecraft every year.Launch day: The end of the countdown is near. The final operations to fill the liquid propellants on the Ariane 5, and then the ground operation tests are carried out on the launcher. During this stage, gtd's staff is working hard all round the Spaceport. In the launch site's bunker, the technical centre, in Des Pêres Mountain where the radar and telemetry installations are, in the meteorological centre where the last conditions before the launch is authorised.At the same time, a support team is configuring a backup of the computer systems in Barcelona, 8,000 km away from the Ariane 5, which is already letting out oxygen steam.Ariane is launched: Once the launcher is in the air, it is controlled on board (by the embedded computer) and from the Jupiter Control Centre (CDC). These two systems were also designed by GTD’s engineers and are currently being operated by GTD’s engineers, too. Once the launcher releases the payloads (at a height of 500 - 600 km), everyone breathes a sigh of relief and starts clapping and cheering and congratulating each other; but our engineers are already thinking about the next mission that starts the following morning...
