One of the two Galileo satellites currently under development, GSTB-V2/A, has arrived at ESA’s European Space Research and Technology Centre to undergo testing.
Two satellites are being developed for the Galileo System Test Bed – Version 2, which will make up the first phase of in the ’in-orbit validation’ of the Galileo system.
The primary mission of the first Galileo satellites is to secure the Galileo frequency filings, validate new technologies for operational use, characterise the radiation environment of the medium earth orbits that the operational satellites will occupy and enable experimentation with live Galileo signals.
The expected satellite lifetime is two years.
ESA maintains a large centre for the testing of space vehicles and their subsystems at its European Space Research and Technology Centre (ESTEC), located at Noordwijk in The Netherlands. The ESTEC Test Centre has the capability of simulating the conditions that spacecraft will experience during launch and once they are in space. ESA will conduct the GSTB-V2/A testing on behalf of the spacecraft manufacturer.
The tests that GSTB-V2/A will undergo include:
The other of the two Galileo satellites, GSTB-V2/B, made by the European consortium Galileo industries, is currently being assembled and tested at the premises of Alenia Spazio in Rome, prior to moving to ESTEC for final testing in the autumn.
The first Galileo launch is scheduled for December this year. The satellite will be carried into space from the Baikonur cosmodrome in Kazakhstan by a Soyuz launcher.
