Development of a Performance Indicator Application to help identify Space Weather Impacts on GNSS

Kurzfassung

In the context of the ESA Space Weather Service Network, the development of Global Navigation Satellite System (GNSS) performance indicators is considered essential to address the increasing end-user demand for space weather information in the navigation domain. A targeted analysis of space weather-related perturbations of technical systems and services in the field of satellite-based navigation has been done to fulfill the requirements in different user domains and related applications. The goal of the P3-SWE-XLII: Space Weather Impact on GNSS Performance Application Development (SWIGPAD) project is to design and develop an application that provides GNSS performance indicators on the basis of existing data supplied by various European research institutes through the ESA Space Weather Service Portal (available at https://swe.ssa.esa.int), tailored to representative use cases developed together with industry and government experts in specific user workshops. The SWIGPAD application provides users access to 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 a numerical and graphical representation of the estimate of position uncertainty based on recent ionospheric conditions, as well as its evolution over time.
