ESA confirms SSTL’s GIOVE-A 'full mission success'

08.04.2008
GIOVE-A, the first satellite in the Europe-led Galileo satellite navigation system celebrates 27 months in orbit this month, marking the completion of its nominal mission lifetime.

The European Space Agency (ESA) has confirmed that the pioneering Medium-Earth Orbit satellite is a 'full mission success' and has contracted Surrey Satellite Technology Limited (SSTL), a spin out from the University of Surrey, to continue operations for an additional year as the satellite continues to perform and provide valuable Galileo services.

Under a €28M contract, the 660kg satellite was developed by SSTL for ESA. The satellite was designed, built and tested in a rapid (30 month) programme and was launched, on schedule, on 28 December 2005.

The primary mission was to secure the Galileo frequency filings at the International Telecommunications Union (ITU). The satellite also played a crucial role as a test-bed for the Galileo payload units, providing a representative signal-in-space for ground-based experimentation with Galileo signals and characterizing the radiation environment for the Medium Earth Orbit (MEO) which will be used by all future Galileo satellites.

Following successful launch and commissioning, the GIOVE-A team undertook an intensive six-week payload in-orbit test (IOT) campaign using the 25m dish at the Science Technology and Facilities Council (STFC) Chilbolton station. Through these activities ESA was able to claim the frequency filings three months before the license expired.

Since commissioning the satellite has achieved a remarkably high operational availability with signals being broadcast for 99.8% of the time over the last year. The primary atomic clock, fundamental to all future Galileo satellites in providing highly accurate positioning and time reference signals, has been operating continuously since June 2007.

Thirteen sensor stations around the world are used by ESA to track GIOVE-A and GPS navigation signals and these have demonstrated that Galileo will be a highly accurate navigation system.

In addition to plaudits from ESA, the European Union and the navigation user community, SSTL’s GIOVE-A team has been recognised with the prestigious Royal Aeronautical Society’s (RAeS) Team Silver Award, as well as the Geoffrey Pardoe Space Award for an exceptional contribution to space, demonstrating first class risk and project management skills in designing and placing into orbit a complex, yet cost-effective satellite. The RAeS awards are considered the most prestigious and long-standing awards in global aerospace honouring achievement, innovation and excellence.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
