Development of a Performance Indicator Application designed to mitigate the Impact of Space Weather on GNSS

Kurzfassung

For the ESA Space Weather Service Network, the development of performance indicators for the Global Navigation Satellite System (GNSS) is considered to be essential to satisfy the increasing demand of end users for space weather information in the field of navigation. Consequently, a targeted analysis of space weather-related disturbances of technical systems and services in the field of satellite-based navigation is required, taking into account the requirements of the different user domains in this field. The objective of the SWIGPAD project is to develop an application, which provides GNSS performance indicators based on existing data provided by various European research institutes through the ESA Space Weather Service Portal (available at https://swe.ssa.esa.int), as well as representative use cases developed by experts from industry and government agencies in dedicated user sessions. This application will supply users with information on current and expected impacts of space weather on the positioning at their particular location. In addition, it will also provide end users in the various GNSS application domains with overall numerical and graphical representation of the estimate of the position uncertainty derived from ionospheric conditions and its evolution over time. In this article the project’s results will be presented.
