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.
