Space Geodesy - this is the science and engineering of using satellites in orbit around planets to measure dynamic characteristics, such as the gravity field, sea level and ice cap variations, as well as plate tectonics. In 2007, GPS World named him as one of the 50 Leaders to Watch for his contributions to the global navigation and positioning industry. He holds a PhD in Satellite Geodesy and Astrodynamics, and is a member of the NASA/CNES Ocean Surface Topography Science Working Team. He is a contributor to news items and documentaries on BBC Radio 1, BBC Radio 4 (Today programme), BBC Radio 5live, BBC News 24 and the World Service. He has carried out numerous consultancies and research contracts, including for the UK Hydrographic Office, the European Space Agency, Tritech Rail, NASA, US Air Force, QinetiQ, and Ordnance Survey. The UCL ,,Space Geodesy and Navigation Laboratory has 15 members: ,,3 academics, 3 PDRAs and ,,9 PhD students.
