Quality controlling GPS estimated atmospheric water vapour via stochastic modelling. Signals from satellites of the Global Positioning System (GPS) can be used to estimate the quantity of atmospheric water vapour. Such information is vital to meteorologists for numerical weather prediction, since lack of atmospheric water vapour knowledge is a significant source of error in short term (0-24 hours) forecasts of precipitation. However, to be of practical use in numerical weather models, the estima ....Quality controlling GPS estimated atmospheric water vapour via stochastic modelling. Signals from satellites of the Global Positioning System (GPS) can be used to estimate the quantity of atmospheric water vapour. Such information is vital to meteorologists for numerical weather prediction, since lack of atmospheric water vapour knowledge is a significant source of error in short term (0-24 hours) forecasts of precipitation. However, to be of practical use in numerical weather models, the estimate of the water vapour content must be accompanied by a realistic, reliable quality indicator. Such quality indicators are not currently attainable using existing GPS data processing methods, with this project aiming to overcome such deficiencies.Read moreRead less
Theoretical and Model Strengthening of Future Global Navigation Satellite Systems (GNSS) to Yield Improved Geospatial Information for Tomorrow's Society. Australia is a significant user of Global Navigation Satellite Systems (GNSSs) because of its utility and for scientific applications (e.g., Earth-, atmospheric- and space-science). The national benefit of improved integer-estimation and model strengthening of integrated GNSSs is twofold: 1. all future scientific GNSS studies will rest on more ....Theoretical and Model Strengthening of Future Global Navigation Satellite Systems (GNSS) to Yield Improved Geospatial Information for Tomorrow's Society. Australia is a significant user of Global Navigation Satellite Systems (GNSSs) because of its utility and for scientific applications (e.g., Earth-, atmospheric- and space-science). The national benefit of improved integer-estimation and model strengthening of integrated GNSSs is twofold: 1. all future scientific GNSS studies will rest on more reliable positioning and related solutions, and 2. the refinements to these high-precision and high-integrity scientific GNSS applications will feed into much-improved geospatial information for tomorrow's society.

Monitoring and Predicting Near Real Time Ionospheric Activities with Multi-satellite Data. The ionosphere affects the transmission of electromagnetic waves, which can result in disturbance or intermission of radio signals being used for communication, navigation and other microwave systems. This project aims to monitor and predict near real-time ionospheric activities with multi-satellite data. The expected outcomes include: 1) an innovative algorithm to calculate the Total Electron Content from ....Monitoring and Predicting Near Real Time Ionospheric Activities with Multi-satellite Data. The ionosphere affects the transmission of electromagnetic waves, which can result in disturbance or intermission of radio signals being used for communication, navigation and other microwave systems. This project aims to monitor and predict near real-time ionospheric activities with multi-satellite data. The expected outcomes include: 1) an innovative algorithm to calculate the Total Electron Content from multi-satellite data; 2) an automated software package for mapping 3-dimensional ionospheric profile; and 3) an improved understanding of the detailed processes and causes of ionospheric events, that can enhance the space weather services for Australia and the world.Read moreRead less
