Abstract

Discussed are the capacities and research steps that should be developed in Europe by 2020‐2025 for future satellite navigation systems and services. Europe needs to operate GNSS services flawlessly, precisely & with integrity, e.g., flawless integrity and bounded inaccuracy almost anywhere, any time for many applications. Multi-Constellation, multi-Frequency GNSS and SBAS as well as assimilation of multi-Sensor data, e.g., assimilation of a diverse set of real-time measurements such as in-situ, vertical sounding, radio occultation, space- & ground-based TECs, EUV emissions, solar wind, geomagnetic activity measurements are required. It is important continue the research in the field of space weather and ionosphere effects with the aim to define and develop ionosphere monitoring and prediction service. Possible upgrade of Galileo ionosphere delay model (e.g., Broadcast Model NTCM-BC) and possible upgrade of thin layer mapping function of GNSS and SBAS (e.g., multi-layer approach can reduce the error by half) are required. Higher order ionospheric correction need to be considered especially in geodetic measurements. Ionospheric scintillation mitigation technique needs to be developed which affects all systems in L band. Also the necessity of real-time ionosphere threat model and robust gradient monitoring is discussed. The ionosphere prediction and advance warning is possible utilizing ACE/ DSCOVR, GOES data of geomagnetic and solar radiation & wind activities.
