Prof. Rizos is an internationally recognized expert in GNSS geodesy; algorithms and methodologies for precise kinematic positioning using GPS and other GNSS signals; the combination of GPS and Differential Interferometric SAR for ground subsidence monitoring; pseudolite and new terrestrial navigation sensor research; multi-sensor integration; and data quality, multipath and RF interference studies. Over the last ten years Prof. Rizos has expanded his work into the areas of GNSS reflectometry, integrated GNSS and WiFi positioning, terrestrial RF-based positioning (including Locata), and investigations on software receivers. This body of research is internationally recognized; the results of which have been published in many refereed journals and presented at ION, IAG, FIG, and other national and international conferences.
Chris is recognized for pioneering navigation research at the Satellite Navigation and Positioning (SNAP) group in the University of New South Wales – today’s premier GNSS and wireless location technology laboratory in Australia. He recently established Australia’s first academic research group in GNSS receiver design using reconfigurable hardware and software-defined radio principles which has led to the development of the “Namuru” GNSS research receiver, the current versions of which are being developed for satellite applications.
Chris has demonstrated sustained commitment to teaching in the fields of navigation, geodesy, and geomatics. He has taught satellite navigation courses at UNSW and professional short courses for over 20 years. More than 20 graduate students from Prof. Rizos’s lab have won ION student prizes/scholarships to attend the ION GPS/GNSS international conferences. He is the author or co-author of four papers in NAVIGATION, 80 ION conference papers, and over 500 journal and conference papers in general.
During his professional career Chris has made numerous contributions to the activities of professional and scientific societies including serving as president of the International Association of Geodesy (2011-2015), a current member of the Governing Board of the International GNSS Service (since 2004), co-chair of the Steering Committee of the Multi-GNSS Asia organization, and as a past member of the ION Satellite Division’s Executive Committee (2004-2006). He has also served on numerous other committees and panels dealing with geodesy, GPS, GNSS or navigation science, including dozens of conference organizing committees.
