Prof Chris Rizos

Chris Rizos is a professor of Geodesy and Navigation in the School of Civil & Environmental Engineering, the University of New South Wales, Sydney. Chris is president of the International Association of Geodesy (IAG), a member of the Executive and Governing Board of the International GNSS Service (IGS), and co-chair of the Multi-GNSS Asia Steering Committee. Chris is currently a member of a number of Australian national committees including the Permanent Committee on Geodesy, the National Committee for Earth Sciences of the Australian Academy of Sciences, and the Steering Committee of the Asia-Pacific Reference Frame Project.

Chris is a Fellow of the IAG, a Fellow of the Australian Institute of Navigation, a Fellow of the U.S. Institute of Navigation, and an honorary professor of Wuhan University, China. Chris has been researching the technology and applications of GPS since 1985, and is an author/co-author of over 600 journal and conference papers.


How can the Geomatics Industry benefit from Advances in GNSS and Geodesy?

We are witnessing the launch of a surge of new navigation satellite systems, with a commensurate increase in satellites and signals, new receiver techniques and an expansion in precise positioning applications. This heralds the transition from a GPS-dominated era – that has served the surveying and geodesy community for almost 30 years – to a multi-constellation GNSS world. GNSS is also revolutionising the field of Geodesy.

The geomatics industry therefore finds itself in a special situation during this historic period, faced with opportunities as well as challenges. Precise Positioning is becoming mainstream, and the influence of the surveying and geodetic communities will grow as a massive new class of users embrace the new GNSS technology and confront issues that surveyors have already had to address, such as datums, CORS infrastructure, integrity, value-added precise positioning services, and education. This presentation will explore some of the issues associated with GNSS and modern geodesy. How will the geomatics industry respond? It can benefit from these developments, but only by being far-sighted, and embraces change and become experts in positioning coordinate reference systems, and geospatial data management.
