Development of a High Integrity Airborne Navigation Sensor for Aviation Communities using Terrestrial Based Infrastructure. The widespread adoption of GPS for aviation, which will allow safer and cheaper air-travel, is hindered by the lack of integrity (truth) information in the system. This research will develop new methodologies, based on low-cost MEMS sensors, to improve the integrity availability of the GPS when augmented with the Ground-based Regional GPS Augmentation System (GRAS).

The widespread adoption of GPS for aviation, which will allow safer and cheaper air-travel, is hindered by the lack of integrity (truth) information in the system. This research will develop new methodologies, based on low-cost MEMS sensors, to improve the integrity availability of the GPS when augmented with the Ground-based Regional GPS Augmentation System (GRAS). These methodologies will be used in the development of next generation airborne navigation sensors. The work builds on the world-leading position that Airservices Australia has made in the development of the GRAS, the navigation expertise of GPSat Systems and the GPS expertise of the QUT.Read moreRead less
Nano-structured sol-gels synthesised under microgravity conditions. This project aims to study the nano-structured silica formation under microgravity conditions using a sol-gel process. In the absence of gravitional forces and associated free convective disturbances, the sol reaction in our preliminary testing with NASA has revealed fundamental reorganisation in nano properties (i.e. fractal dimension, pore size, surface area and pore volume) as compared to tests carried out under normal gravi ....Nano-structured sol-gels synthesised under microgravity conditions. This project aims to study the nano-structured silica formation under microgravity conditions using a sol-gel process. In the absence of gravitional forces and associated free convective disturbances, the sol reaction in our preliminary testing with NASA has revealed fundamental reorganisation in nano properties (i.e. fractal dimension, pore size, surface area and pore volume) as compared to tests carried out under normal gravity conditions. This is a key feature of scientific interest for the production of nanomaterials for applications such as linear and non-linear optical materials and quantum materials.Read moreRead less
