GIOVE-A2 to secure the Galileo programme
Today, ESA awarded a contract to Surrey Satellite Technology Limited (UK) for initial activities leading to the construction of a second spacecraft for the Galileo satellite navigation system. Named GIOVE-A2, the new satellite (estimated total value 25 to 30 million Euros) will be based on the company’s proven GIOVE-A technology. From now on, there will always be a European navigation satellite in space.
ESA wishes to guarantee the continuity of the Galileo programme with the permanent presence of a spacecraft in orbit. This will maintain European rights to the frequencies and allow continuation of the experiments initiated with the successful GIOVE-A mission and planned for the upcoming GIOVE-B satellite.
GIOVE-A2 will help maintain the critical International Telecommunications Union (ITU) frequency filing secured by its predecessor for a further 27 months and facilitate further development of ground equipment.
Monitoring of the space environment will also be an important ongoing mission objective for the new satellite. GIOVE-A was the first European satellite to be launched into medium Earth orbit (MEO) and it carries two environmental monitors. These units have been operated almost continuously since launch and are gathering vital data about the Galileo orbit environment that will help in the design of the full constellation.
