Summary on Grant Application Form |

We propose to study the influence of ionospheric scintillation on GPS and interoperable systems. The study will address specifically the issues of integrity, accuracy and availability of GPS. Significant disturbances of the ionosphere can occur in the years of high sunspot activity. The next Solar Maximum is to occur between 2000 and 2002. Ionospheric scintillation mostly takes place in equatorial and auroral regions, but north-south gradients can also affect mid-latitude regions. Many applications of GPS will suffer from loss of accuracy, integrity and availability during such disturbances (eg stand alone and differential navigation for marine, aviation or land applications, environmental monitoring, transport, and geodetic surveying). Our research will be based on GPS observations themselves. Geomagnetic indices may be used to assess ionospheric activity, but a GPS based index is expected to give optimum correlation. State-of-the-art GSV4000 GPS receivers, co-located with permanent stations in Northern Europe and in the UK, will be used to produce scintillation parameters and correlate these with differential and augmentation service performance. Different types of receivers will be deployed and their performance compared, and the effects on different GPS observing techniques will be assessed. A prime objective of the research is to develop warning/mitigation mechanisms for GPS users.EngProg\
