Ariane 5 Launch extends Galileo's global reach



With the successful launch of four other Galileo satellites by Ariane 5, the Galileo constellation rose to 26 satellites and expanded the global coverage of the constellation.

Ariane 5 flight VA244, operated by Arianespace on behalf of the European Space Agency (ESA), on July 25 at 11:25 GMT (13:25 CEST, 08:25 local time) from the European Spaceport in Kourou in Taking off French Guiana and carrying the Galileo satellites 23-26. The first pair of 715-kilogram satellites were released almost 36 hours after take-off, while the second pair separated 20 minutes later, according to an ESA press release.

They were fired in their target of 22 922 km altitude by the US Dispenser on the Ariane 5 upper stage. In the coming days, this quartet will be directed by the French space agency CNES on behalf of the Galileo operator SpaceOpal for the European Global Navigation Satellite System Agency (GSA). There they will begin testing SpaceOpal for about six months to prove their readiness to join the functioning Galileo constellation.

"Galileo is ESA's largest satellite constellation ever built in a very short space of time. In the last four years, only full-featured satellites have been added," said Jan Wörner, ESA Director General.

"We must thank our industry partners OHB (DE) and SSTL (GB) for the satellites and Thales Alenia Space (FR / IT) and Airbus Defense and Space (GB / FR) for the ground segment and all their subcontractors across Europe for their continued support of the program, and together with ESA, the entire industry team has worked hard for the point we are now in, and this cooperation has proved very successful, as we can show Galileo. "

Paul Verhoef, Director of ESA Navigation added: "Galileo has been providing world-wide first services since December [15] 2016 and today has more than 100 million users growing fast.Today's satellites will provide Galileo's global coverage Increase performance, which is generally recognized as excellent.

Officials declared the launch of a success and gave the European Galileo Navigationfl otte 26 satellites, including 22 launched in the last four years. Wednesday's mission was the last flight of the Ariane 5 ES version of Europe's workhorse launcher. Future Ariane 5 launches will use the Ariane 5 ECA configuration.

"This is the end of the current phase of the Galileo mission, but our pace is steady, with another 12 Galileo" Batch 3 "satellites in preparation as an in-orbit replacement and replacement for the oldest Galileo satellites Launched in 2011 to seamlessly integrate the system into the future,

A new generation of Galileos are planned for the middle of the next decade, providing enhanced performance and additional features that make Galileo a permanent feature of the global GNSS landscape preserved.
