<Description>The signals transmitted by the Global Navigation Satellite System (GNSS) satellites are delayed
by ionospheric/plasmaspheric electrons before reaching the Swarm GNSS antenna. From the
GNSS signal delay we can estimate slant total electron content (STEC), which is defined as
‘integrated’ electron density along the line of sight from Swarm to GNSS satellites.</Description>

<Caveats>It is recommended to use absolute VTEC data with corresponding elevation angles of the GPS
rays of at least 50◦ . The recommendation is given since the uncertainty of the mapping function increases with decreasing elevation angle.
Note that AMDA keeps STEC / VTEC data for the highest elevation angle only.
