Looking on is the President of the RIN, Captain James Taylor. Spirent was selected for this year’s award to recognize its leading role in the evolution of global navigation satellite systems (GNSS) since 1985, and joins the European Space Agency, the UK National Air Traffic Services (NATS), the Russian GLONASS system, and others who have previously received the award. “We are extremely honoured to have been recognized by the Institute in this way,” said Martin Foulger, general manager of Spirent’s Positioning Technology Unit. “Spirent has been at the forefront of GPS and other GNSS development for 30 years, so to join the other winners of this award is a great acknowledgement of the technical innovation and commercial success driven by the Spirent team in Paignton.” His Royal Highness The Duke of Edinburgh (right) congratulates Eric Hutchinson, Spirent’s Chief Executive Officer (left), after receiving the Royal Institute of Navigation (RIN) Duke of Edinburgh Navigation Award for Technical Achievement. Peter Chapman-Andrews, Director of the Royal Institute of Navigation, commented: “Spirent is a well-known and well-respected leader in PNT testing. This wholly-deserved award is the Institute’s way of recognizing Spirent’s significant contribution over many years towards helping the world evaluate and improve performance of navigation and timing receivers, systems and applications.” Spirent delivers navigation and positioning test equipment and services to governmental agencies, major manufacturers, integrators, test facilities and space agencies worldwide. Spirent’s portfolio has recently been updated with new technology that includes innovations not seen elsewhere, including the most flexible simulation systems covering the full range of GNSS signals and the world’s smallest hi-fidelity, portable PNT record and playback system. Spirent has recently opened three services labs, in UK, USA and China, to further support positioning and timing development and innovation.
