Time: 15.30, Friday 25th January 2013

Place: Vietnamese German Centre, HUST Campus

Abstract: Phase multipath is one of the most crucial error sources in centimetre or millimetre level GNSS high precision positioning.  Short-delay multipath is still especially difficult to detect or mitigate by the state-of-the-art hardware-based techniques.  Therefore, processing algorithm-based multipath mitigation methods are crucial for the further improvement of positioning accuracy, either integrated with other techniques or in a stand-alone mode.   This seminar describes the background of GNSS multipath errors, effect of multipath, hardware-based multipath mitigation techniques, and processing algorithm-based multipath mitigation techniques in particular. Before presenting the technical content, a brief introduction of the University of Nottingham Ningbo China (UNNC) is given. 


Biography: Lawrence Lau is an Assistant Professor in Geodesy and Surveying at the University of Nottingham Ningbo China (UNNC). He obtained his PhD at University College London (UCL) in 2005. Before joining UNNC, he worked as an Associate Professor in the Institute of Geomatics in Barcelona from March 2010 to September 2011. In 2004 – 2010, he was a Postdoctoral Research Fellow at (UCL), UK. In his about 6 years at UCL he worked on several research projects, including two UK EPSRC-funded research project called SPACE, iNsight, two EU FP6 projects called BEAR and ANASTASIA, and two consultancy projects. SPACE was undertaken by a consortium of eleven UK university and industrial groups and iNsight (an on-going project) is undertaken by a consortium of thirteen UK university and industrial groups. Before joining UCL, he worked as a technical analyst in the Nottingham Scientific Ltd. (2002 - 2004) in design and development of the new European GNSS (Galileo); he worked on two European Commission (EC) and European Space Agency (ESA) funded Galileo System Test Bed (GSTB-V1: Orbit Determination and Time Synchronisation, and GSTB-C0) projects. In 1999 – 2002, he worked in the Hong Kong Polytechnic University as a Research Associate for several vehicle navigation projects.
