Two satellites are on orbit as spares to cover any issues with the primary spacecraft. This is Europe\u2019s largest ever fleet of satellites, operating in the new environment of medium-Earth orbit.<\/p>\n<h4 class=\"widget-title penci-border-arrow\">See Also<\/h4>\n<ul>\n<li>UPDATES Ariane 5 ES Launch<\/li>\n<li>65 Launch Vehicle Manuals (L2)<\/li>\n<li>Click here to Join L2<\/li>\n<\/ul>\n<p>Europe\u2019s own GPS constellation was deemed to be a major requirement, so as to ensure it wasn\u2019t stuck with having to rely on US or Russian systems.<\/p>\n<p>This decision is deemed to be a wise one, given the increasingly uncertain geopolitical climate that has followed since Galileo\u2019s inception. A plot twist also involves the UK, which has been a major financial and technical contributor to the system but has been threatened with a lockout due to the UK population\u2019s decision to leave the European Union.<\/p>\n<p>The launch campaign began with the launch of the first two experimental satellites, Giove-A, and Giove-B, orbited by Arianespace\u2019s Starsem affiliate on Soyuz launchers from Baikonur Cosmodrome in 2005 and 2008.<\/p>\n<p>The deployment of the system has utilized an element of international cooperation, with the Russian Soyuz rocket \u2013 albeit under the operation of Arianespace, taking the system to Full Operation Capability (FOC), followed by the first with the Ariane ES, which was the eighth&nbsp;Galileo mission \u2013 bringing the number of satellites in space up to 18 at that time.<\/p>\n<p>Issues during previous launches with Soyuz rockets caused some replanning of the full deployment schedule. However, the Ariane 5 ES\u2019s final \u2013 and successful \u2013 launches have improved the pace allowing for the system to be in full use with an acceptable timescale.<\/p>\n<p>The latest four satellites&nbsp;(23 to 26 \u2013 FOC-M8) are named Anna, Ellen, Samuel and Tara. Each of the satellites is named after children that won the European Commission\u2019s Galileo drawing competition.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" aria-describedby=\"caption-attachment-57348\" class=\"size-full wp-image-57348\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-141652.jpg\" alt=\"\" width=\"1766\" height=\"839\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-141652.jpg 1766w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-141652-350x166.jpg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-141652-630x299.jpg 630w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-141652-768x365.jpg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-141652-1170x556.jpg 1170w\" sizes=\"(max-width: 1766px) 100vw, 1766px\"><\/p>\n<p id=\"caption-attachment-57348\" class=\"wp-caption-text\">The four new satellites head of launch \u2013 via ESA<\/p>\n<p>These satellites \u2013 which weigh between 715 kg and 717 kg \u2013 were built by OHB System in Germany with U.K.-based Surrey Satellite Technology supplying the navigation payloads.<\/p>\n<p>The A5 dispenser system will keep the quartet of Galileo satellites in place during ascent, before deploying them in rapid sequence at a targeted release altitude of 23,222 km.<\/p>\n<p>The 447 kg dispenser, designed by Airbus Defence and Space, is made from a combination of metal and composite materials for maximum stiffness, the dispenser has undergone very comprehensive testing at Airbus Defence and Space near Bordeaux, France, and the IABG testing centre in Ottobrunn, Germany \u2013 using both Galileo engineering models and an actual flight satellite, including fit, shock and separation testing.<\/p>\n<p>The target orbit was actually 300 km below the Galileo constellation\u2019s final working altitude: this leaves the Ariane\u2019s EPS upper stage in a stable \u2018graveyard orbit\u2019, while the quartet of Galileos maneuver themselves up to their final set height.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-57350\" class=\"size-full wp-image-57350\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-143302.jpg\" alt=\"\" width=\"1238\" height=\"606\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-143302.jpg 1238w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-143302-350x171.jpg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-143302-630x308.jpg 630w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-143302-768x376.jpg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2018\/07\/2018-07-24-143302-1170x573.jpg 1170w\" sizes=\"(max-width: 1238px) 100vw, 1238px\"><\/p>\n<p id=\"caption-attachment-57350\" class=\"wp-caption-text\">A Galileo satellite in its orbit \u2013 via DLR<\/p>\n<p>The test campaign met all objectives, confirming the behavior performs as predicted, after which the dispenser was shipped to Europe\u2019s Spaceport in French Guiana.
