The objective of a new National Positioning Infrastructure (NPI) is to provide real-time, centimetre-level positioning services regardless of location. In support of this objective, this project is developing the geodetic techniques, tools and standards required to implement the next generation geodetic datum which will underpin the NPI.
Continuous Operating Reference Station (CORS) Networks: Surveying and Geospatial Engineering (SAGE) Research: in this video, Professor Chris Rizos talks with Dr Craig Roberts about using GPS signals and CORS networks in earth science research to measure movements in the Earth’s surface:
Professor Rizos talks about how CORS networks around the world take GPS signals from positioning satellites to deliver centimetre accurate coordinates which can be used to help scientists to measure and understand earthquakes and other movements on the surface of the Earth. He also talks about how CORS networks are also increasingly used in other applications including precision agriculture, mining and infrastructure development.
