Abstract

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.
