On 24th October the European Space Agency (ESA) reported that a helicopter recently flew over an Alpine valley to gather data on how Europe’s two satellite navigation systems – EGNOS and Galileo – will work together in future.

The helicopter flew over the Galileo Test and Development Environment – GATE – in Berchtesgaden, Germany. The helicopter flew a variety of manoeuvres, from fast loops to mid-air hovering, to see how satnav signals were received in
practice.
