Galileo Payload Testbed arriving at ESTEC

The first Galileo Second Generation hardware has begun testing, with test versions of the satellites’ navigation payloads undergoing evaluation by Airbus Defence and Space at their Ottobrunn facility in Germany and by Thales Alenia Space at ESA’s ESTEC technical centre in the Netherlands.

“In the second test phase the actual far-field measurements will be performed, using another feature of the chambers. Thanks to a pair of specially-shaped paraboloid reflectors, the signal from the testbed can be reshaped as if it has travelled the very long distance that actual Galileo signals need to stretch, all the way from an altitude of 23 222 km down to Earth’s surface.”

Dirk comments:“On the Airbus side the methodology is substantially the same, except the far-field measurement are currently being performed, to be followed by the near-field measurements.”

About Galileo

The Galileo system is operated by the EU Agency for the Space Programme, EUSPA, based in Prague. ESA and EUSPA are partnering on respectively the development and operations of Galileo.

ESA is in charge of the design, development, procurement and qualification of Galileo satellites and their associated ground infrastructure on behalf of the European Union, the system’s owner.
