Description
The GNSSs (e.g. GPS, Galileo, Glonass, Beidou) allow the determination of the ionospheric total electron content (TEC) between a satellite and a ground receiver. It is thus possible to monitor the impact of the space weather on the upper part of our atmosphere (i.e the ionosphere) using a network of GNSS stations.
This paper presents GNSS-based TEC maps delivered from different agencies with different latencies (i.e. minutes to days), area extents (i.e. local to global), grid resolutions (i.e. few degrees to lower than 1°) and time scales (i.e. few minutes to hours). Additionally, we will discuss the effectiveness of GNSS-based products especially during disturbed Space Weather conditions (i.e. ionospheric storms).
