2016 Thurlow Dr. Paul Groves

Dr. Paul D. Groves is a Senior Lecturer (associate professor) at University College London (UCL). He in an inventor of the GNSS shadow-matching technique, and has contributed to innovations in terrain-referenced navigation, visual navigation, positioning using AM radio broadcasts, heterogeneous feature-matching, detection of GNSS NLOS reception and multipath interference, and context-adaptive navigation. He also authored, “Principles of GNSS, Inertial and Multisensor Integrated Navigation Systems.”

Dr. Groves proposed the shadow-matching technique that combines GNSS with 3D city models and, with colleagues at UCL, demonstrated this in real time on a smartphone. Additionally, they developed 3D-mapping-aided GNSS ranging algorithms and integrated them with shadow-matching to achieve a horizontal single-epoch positioning accuracy of 4m with a u-blox receiver and 7m with an Android tablet; significantly better than conventional GNSS positioning. He has led the development of the multipath and non-line-of-sight mitigation work at UCL.

Dr. Groves recognized that to obtain reliable positioning in all environments at a reasonable cost, it is necessary to collect as much location-dependent information as possible and extract the best possible position from it; and combine conventional approaches using positioning signals and motion sensors with newer techniques using opportunistic signals and environmental features. He introduced the concept of contextadaptive navigation to address the challenge of adapting to changes in context, and he also proposed a modular integration architecture for complex multisensor navigation systems.

Dr. Groves, with colleagues at UCL, has developed several new navigation technologies, including differential positioning based on modulation correlation of radio broadcasts, mapping of heterogeneous environmental features such as magnetic anomalies, barometric height, ambient light and road signs for navigation during GNSS outages, and techniques to obtain better navigation performance out of very-low-cost inertial sensors without an expensive laboratory calibration.

Dr. Groves received his BA, MA and PhD in Physics from University of Oxford. He is a Fellow of the Royal Institute of Navigation, and currently serves as an Associated Editor of NAVIGATION, Journal of The Institute of Navigation and of The Journal of Navigation. He is an enthusiastic educator and has mentored 40 students.
