Galileo Working Well
2014-02-12 12:08:28

[ Watch The Video: Galileo Validated in Orbit VNR ] ESA The in-orbit validation of Galileo has been achieved: Europe now has the operational nucleus of its own satellite navigation constellation in place – the world’s first civil-owned and operated satnav system. In 2011 and 2012 the first four satellites were launched into orbit. Four is the minimum number needed to perform navigation fixes. In the following year, these satellites were combined with a growing global ground...

Galileo’s South Pacific Ground Station Endures Freak Rains And Flood
2013-07-15 09:41:51

ESA Think your summer has been bad? Engineers manning Galileo's South Pacific ground station on New Caledonia found themselves marooned by heavy rains and a flash flood -- though the station carried on operating regardless. Torrential rains lashed this French-administered group of islands at the start of July. The south coast of New Caledonia's main island of Grand Terre recorded more than 700 mm of rain in 24 hours -- the yearly average being roughly 1100 mm. The Galileo ground...

Third Galileo Satellite Transmits Test Signals
2012-12-04 14:52:07

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA) Third Galileo satellite has sent its first test navigation signals back to Earth, and has broadcasted signals across all three Galileo bands. The pair of Galileo satellites launched this fall join two others that were launched in October 2011. The first set have reached their final orbital position and are in the middle of testing. The third satellite, known as FM3, transmitted its first...

Galileo Satellites Join The Soyuz Rocket On Pad For Friday Launch
2012-10-10 10:01:08

The two Galileo satellites and their upper stage have been enclosed within their protective fairing, and moved to join the Soyuz rocket on the launch pad. The halves of the fairing were sealed together around the satellites, their supporting dispenser and Fregat-MT upper stage on Friday, within the Upper Composite Integration Stand of building S3B of Europe´s Spaceport in French Guiana. Yesterday, the Upper Composite was moved to the launch site, for vertical mating to its...

Galileo Satellites Ready For Launch
2012-10-01 12:58:52

Lee Rannals for redOrbit.com - Your Universe Online The twin Galileo satellites are now fueled and ready for the launch planned for the evening of October 12, according to the European Space Agency (ESA). ESA said that technicians filled up the two satellites' tanks with hydrazine fuel, which is used to maintain the satellites' attitude and orbital position during their 12-year lifetime. The Galileo satellites will be transported to medium orbit by the Fregat fourth stage of their...

Fourth Galileo Satellite Now At French Guiana Launch Site
2012-08-21 09:40:50

The next two Galileo satellites are now in place at Europe´s Spaceport in French Guiana, being prepared for their shared launch this autumn. The fourth Galileo satellite flight model arrived at Cayenne Airport in French Guiana on Friday 17 August, flown from the Thales Alenia Space facility in Rome aboard an Ilyushin aircraft. Cocooned inside a protective air-conditioned container, the satellite was then transported to the preparation facility at the Guiana Space Centre to join the...

ESA’s Next Galileo Satellite Arrives In French Guiana
2012-08-08 07:56:42

Lawrence LeBlond for redOrbit.com - Your Universe Online After traveling nearly 5,000 miles from Thales Alenia Space in Rome, Italy, the next Galileo navigation satellite arrived at Europe´s Spaceport in French Guiana August 7 to begin preparations for an October launch into orbit. The satellite, enclosed in a protective, air-conditioned container, was accompanied by a four-person team from Thales, plus two representatives, one each from Astrium and the European Space Agency (ESA)....

exactView-1 Satellite In Orbit And Operational
2012-07-27 05:47:48

Surrey Satellite Technology Ltd Announcement Surrey Satellite Technology Ltd (SSTL) announced Thursday the successful separation from the Soyuz launcher and subsequent operation of mission-critical systems onboard the exactView-1 satellite, which was built by the Company under contract to prime contractor COM DEV Canada for exactEarth. exactView-1 separated from the Soyuz launch vehicle´s Fregat upper stage in low Earth orbit approximately 2 1/2 hours after launch.  SSTL has...

ESA Retires GIOVE-B After Four Years Of Service
2012-07-25 13:40:21

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced on Tuesday that it has retired its GIOVE-B experimental navigation satellite. The satellite initiated a thruster firing yesterday, raising GIOVE-B's orbit by about 18 miles, taking it steps closer to a satellite graveyard up in orbit. More thruster firings will take place in the next three weeks, so that by mid-August the experimental satellite will be 372 miles above its original orbit....

Trial By Vacuum Brings Next Galileo Satellites Closer To Launch
2012-06-14 13:35:08

The next two Galileo navigation satellites have now endured the harsh vacuum and temperature extremes of space on the way to their scheduled 28 September launch. The fourth satellite completed 20 days of thermal vacuum testing at Thales Alenia Space Italy´s plant in Rome at the start of June. The third satellite completed the same tests the previous month. “These two satellites are almost identical to the first two Galileo satellites that were launched last 21 October,”...
