Many applications of Global Navigation Satellite System (GNSS) technologies, including surveying, mapping and precise navigation, require real-time positioning and centimetre scale accuracy.
To support these applications, many countries are establishing dense networks of Continuously Operating Reference Stations (CORS), positioned less than 40 km apart. Given Australia’s large and sparsely populated regions such dense CORS networks cannot be economically justified.
The aim of this project is to investigate enhancements that could be made to sparse networks of reference stations to enhance their accuracy to the same level as dense CORS networks. The study will focus on improving understanding of atmospheric conditions, currently a major limiting factor in the development of sparse networks.
The main expected outcomes of this project are a new network platform and a new real-time atmospheric model for networked real-time kinematic positioning services. This atmospheric model will be designed to maximise the benefits of the CORS network infrastructure over large areas.
This is a joint research venture between the RMIT University SPACE Research Centre (Formally SPAN) and The University of New South Wales.
