    ESA's Galileo mission

    Could not find a thread dedicated to ESA's Galileo mission. Reason for creating this thread now is the Galileo system has hit a major problem and is down from the 11th of July.

    The European Union’s satellite navigation system, Galileo, has been down since July 11. The outage, the longest-ever of such a service, highlights how difficult it will be to wean the world off its dependence on the U.S., Russian and Chinese militaries for critical (and lucrative) navigation services.

    At the time of writing, Galileo’s 24 satellites were listed as “not usable” on the system’s website. No time frame has been announced for bringing them back online, and no specific explanation has been provided beyond a reference to “a technical incident related to ground infrastructure.”

    After 6 days in the wilderness Galileo is back.

    Europe's Galileo satellite navigationsystem, a rival of the American GPS network, is back in service after a six-day outage, its oversight agency said on Thursday.

    "Commercial users can already see signs of recovery of the Galileo navigation and timing services, although some fluctuations may be experienced until further notice," the European Global Navigation Satellite Systems Agency said in a statement.

    The system of 22 orbiting satellites, which helps to pinpoint and track mobile telephone users and vehicles, began experiencing problems last Friday.

    "ESA sets stage for three-way competition to build next-generation Galileo constellation "

    The European Space Agency is preparing to select two companies to build the second generation of Galileo navigation satellites under contracts to be signed in early 2021.

    The ESA-led competition, arranged on behalf of the European Commission, pits rising German manufacturer OHB against European heavyweights Thales Alenia Space and Airbus Defense and Space, Paul Verhoef, ESA director of navigation, told SpaceNews by email. “The intention is to retain two suppliers in a dual-source mode providing these satellites,” he said.

    ESA will initially order two satellites apiece from the selected providers. Follow-on contracts will cover the next 12 satellites in a constellation that will eventually consist of 24 active satellites and up to six spares.

    The contract has been awarded.

    The work is going to the continent's two dominant space manufacturers - Airbus and Thales Alenia Space.

    They will make six spacecraft each for the global navigation satellite system, with the first of them likely to go into orbit in 2024.

    During its work, Galileo flew 4.6 billion kilometers, approached Jupiter, and circled the planet several dozen times. The satellite cost the United States $ 1.5 billion. For the first time in the history of space exploration, scientists have obtained accurate data on the atmosphere of Jupiter and on the natural satellites of the giant - Europa, Ganymede and Callisto. The information received from the station was so valuable that the specialists extended the Galileo's operating time three times.
