Research summary

Paul Groves' robust positioning and navigation research program supports the vision of a world where a real-time low-cost position solution within three metres is available in all places at all times. This includes challenging environments such as dense urban areas, indoors, underground and underwater. It also includes times when some technologies may become unusable due to signal interference, weather disturbances, unusual dynamics or equipment failure. To achieve this vision, a combination of different navigation and positioning technologies, both conventional and new, must be used.

Current research projects include:

* Pedestrian motion analysis and modelling in support of indoor and outdoor positioning;

* Better navigation performance using ultra-low-cost inertial sensors;

* Positioning using location signatures from multiple environment sensors;

* Better mobile positioning using advanced 3D mapping to enhance satellite navigation;

* Intelligent positioning in cities using GNSS and enhanced 3D mapping;

* Context detection, categorization and connectivity for advanced adaptive integrated navigation.

Recently completed projects include:

* GNSS shadow matching: A new positioning techniques for urban canyons using 3D city modelling;

* Novel GNSS multipath and NLOS reception mitigation techniques for urban areas;

* Differential positioning by modulation correlation using signals of opportunity;

* Survey of non-GNSS positioning technologies and integration architectures for coastal and port approach navigation.

Other research activities include:

* Future integration architectures for complex multi-sensor navigation and positioning systems;

* Step and turn detection for pedestrian dead reckoning using inertial sensors;

* How to perform offshore positioning if GNSS completely fails.

See the "Research activities" tab for further details.

Paul Groves specialises in robust positioning and navigation techniques for challenging environments. These are a key enabler for many different engineering problems. He is interested in all navigation and positioning technologies, including global navigation satellite systems (GNSS), inertial sensors and environmental feature matching. Particular focuses include exploring novel positioning techniques, developing reliable urban positioning and integrating complex sensor combinations in multiple contexts. He is also author of the ~800-page book Principles of GNSS, Inertial, and Multisensor Integrated Navigation Systems (Artech House, 2008 and 2013).

Paul joined UCL's Space Geodesy and Navigation Laboratory (SGNL) in 2009 after 12 years at DERA and QinetiQ. He is an inventor of the GNSS shadow-matching technique and other approaches to 3D-mapping-aided GNSS. He 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 has developed algorithms for all forms of INS/GNSS integration, multisensor integration, transfer alignment, quasi-stationary alignment, zero-velocity updates, pedestrian dead reckoning, GNSS C/N0 measurement, and inertial navigation, and has laid the foundations for context-adaptive navigation. He also has extensive experience in GNSS and IMU software simulation. Paul is a Fellow of the Royal Institute of Navigation, an active member of the Institute of Navigation (ION), a Chartered Physicist and is the recipient of the 2016 ION Thurlow Award. He is an Associate Editor of  Navigation: Journal of the ION and of The Journal of Navigation. He has helped to organize a number of conferences and seminars and acted as a peer reviewer for numerous journals.
