Performance Indicator Application Development to address the Impact of Space Weather on GNSS

Kurzfassung

For the ESA Space Weather Service Network, the development of Global Navigation Satellite System (GNSS) performance indicators is deemed crucial to meet the increasing end-user demand for space weather information in the navigation domain. Hence, a dedicated analysis of space weather-related disturbances of technical systems and services in the field of satellite-based navigation is required, while taking the requirements of the different user domains in this field into account. The SWIGPAD project is aimed at developing an application that will provide GNSS performance indicators based on existing data made available by various European research institutes through the ESA Space Weather Service Portal (available at https://swe.ssa.esa.int), along with representative use cases designed by industry and government experts in dedicated user sessions. This application provides users with information on current and expected impacts of space weather on positioning at their particular location. It also presents end users in the various GNSS application domains with a comprehensive numerical and graphical representation of the estimate of position uncertainty resulting from ionospheric conditions and its evolution over time. This article presents the results of the project.
