Director of Graduate Research, The School of Earth and Planetary Sciences. Dr. Ahmed El-Mowafy is the leader of the GNSS Satellite Positioning and Navigation group, Curtin University. The group has a focus on developing new theories and methods that enable future GNSS to fulfil the high-accuracy requirements of tomorrow’s geospatial information needs in the Earth, atmospheric, and space-sciences, in addition to monitoring climate change and our atmosphere (tropo- and ionosphere) and sea level variation. Ahmed has more than 30 years of expertise in the area of Global Navigation Satellite Systems (GNSS) and engineering surveying. His research focuses on precise positioning, such as precise point positioning (PPP), PNT for the monitoring of climate change, integrity monitoring, data validation and quality control, and estimation theory. Dr. El-Mowafy's research projects are linked to practical applications with significant economic and social value, such as with respect to climate change, transport, mining, aviation, precision farming, machine automation, surveying, and construction.
