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 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....

First Galileo Satellite GIOVE-A Reaches Sixth Anniversary
2012-01-13 04:46:22

British satellite manufacturer Surrey Satellite Technology Ltd (SSTL) on Thursday celebrated the sixth year of transmission of signals from its GIOVE-A satellite, which signaled the start of Europe´s ambitious Galileo satellite navigation program when it secured vital frequency filings on the 12th January 2006. The 660kg GIOVE-A satellite was designed, built and tested in only 30 months for just 28 million Euro — demonstrating that innovative low cost small satellites could...

The European Space Agency (ESA) and Paris, France-based launch company Arianespace announced on Monday that they had signed a contract for the launch of four testbed satellites in Europe's Galileo satellite-navigation system. The two parties made the announcement at the outset of the Paris Air Show at Le Bourget airport. Although financial details of the agreement were not disclosed, they said the satellites will be launched in pairs by two Russian-built Soyuz launchers from ESA's space...

A surge of space radiation recently shook the Giove-B satellite and forced it into "safe mode" for two weeks. Launched earlier this year, Giove-B and its sister demonstrator Giove-A, are the first European missions to fly in the high-radiation environment of a medium-Earth orbit (MEO), at an altitude of 24,000km. Giove-B carries the technologies that will be incorporated into the Galileo network when it becomes operational. European Space Agency (ESA) relies on the test spacecraft for future...

Following a successful launch on 27 April, GIOVE-B began transmitting navigation signals today. This is a truly historic step for satellite navigation since GIOVE-B is now, for the first time, transmitting the GPS-Galileo common signal using a specific optimized waveform, MBOC (multiplexed binary offset carrier), in accordance with the agreement drawn up in July 2007 by the EU and the US for their respective systems, Galileo and the future GPS III.These GIOVE-B signals, locked on-board to a...

Earlier this week, GIOVE-A successfully transmitted its first navigation message, containing the information needed by user receivers to calculate their position. Prior to reaching this milestone, the satellite had been broadcasting only the data needed for measuring the receiver-to-satellite distance. The first Galileo navigation message was created by the navigation signal generator unit on board GIOVE-A, using content prepared by the GIOVE Mission Segment. This week-one navigation message...

Fourteen laser ranging stations participated in a campaign to track ESA's GIOVE-A satellite during the spring and summer of 2006, providing invaluable data for the characterisation of the satellite's on-board clock. The campaign was coordinated by the International Laser Ranging Service (ILRS) and the GIOVE Processing Centre at ESA-ESTEC. GIOVE-A, developed by Surrey Satellite Technology Ltd (UK), was launched from Baikonur Cosmodrome on 28 December 2005 and placed into a medium Earth...

By Richard Balmforth MOSCOW (Reuters) - The European Union launched its first Galileo navigation satellite on Wednesday, moving to challenge the United States' Global Positioning System (GPS). Russian space agency Roskosmos said the 600 kg (1,300 lb) satellite named Giove-A (Galileo In-Orbit Validation Element) went into its orbit 23,000 km (15,000 miles) from the earth after its launch on a Soyuz rocket from the Baikonur cosmodrome in the middle of Kazakhstan's steppe. "The launch of Giove...
