GIOVE-A, the first test satellite for Europe's Galileo navigation system, is to remain in service for a further 12 months.

The satellite, already in orbit for 41 months - 14 months beyond its original mission design life - will continue to provide critical data to all of the ground users experimenting with Galileo navigation signals.

The European Space Agency (ESA) recently approved an extension of the GIOVE-A mission for a further twelve months, which provides for operations to be supported to the end of March 2010.

GIOVE-A carries radiation monitoring instruments which gather invaluable data which is processed and analysed to assist experts characterise the environment in the Galileo orbit, one of the primary objectives of the GIOVE missions.

During routine maintenance on 28th April, an anomaly was discovered onboard GIOVE-A, which required payload transmissions to be temporarily switched off. Full operations were returned on 27th May with the broadcast of L1-E5 navigation signals and there has been no impact on the ability of GIOVE-A to continue supporting payload operations.

Launched on 28th December 2005, GIOVE-A was designed and built by SSTL within a 30-month, 28M Euro contract.

The 600kg satellite had four mission objectives: to secure the frequencies allocated by the International Telecommunications Union (ITU) for the Galileo system; to demonstrate critical technologies for the navigation payload of future operational Galileo satellites; to provide representative Galileo signals in space to support experimentation activities and to characterise the radiation environment of the orbits planned for the Galileo constellation - all of which have been achieved. SSTL also played a significant role in the in-orbit testing of the second Galileo satellite, GIOVE-B, launched in 2007.

Recently, SSTL teamed with OHB-Systems of Bremen, Germany to submit a proposal to ESA for the provision of fully operational Galileo satellites to be launched before 2013. SSTL is utilising the experience gained from GIOVE A and GIOVE-B to help ESA and the EC ensure that Galileo will be a success for Europe.
