Summary on Grant Application Form
The first Global Navigation Satellite System (GNSS) widely available to civilian users is the Global Positioning System (GPS), and this has been adopted successfully for many different applications. However, there are limitations in using GPS for applications requiring a high degree of accuracy or integrity. These can be divided into two areas (i) atmospheric phenomena and (ii) local environment factors. This proposal is concerned with the former area and in particular the effects of the ionosphere over Europe. This research fellowship has an agreed co-operation with the European Space Agency and will assist the UK in retaining an internationally leading role in ionospheric research during the development and launch of Europe's own GNSS, Galileo, planned to be fully operational in 2008. GPS data will be used in a novel ionospheric imaging technique to create large-scale, four-dimensional maps of electron concentration. The ionospheric features collocated with regions of signal loss and scintillation will be identified and the physical mechanisms for the scintillation will be investigated. The results will be of interest to the plasma physics community and to those involved with improving GPS and with the development of the new European Galileo System.
