<name>eSWua: TEC variation and rate of change of TEC from 50 Hz GNSS signal samples</name>
<description>
The carrier-derived (integrated Doppler) TEC is evaluated from the corresponding two
different carrier phase GNSS observables and provides accurate information on the TEC
variation over time. TEC variations (dTEC, expressed in TECu) are provided every 15 seconds
(dtec0, dtec30_15, dtec45_30, dtec60_45) for each available GNSS satellite link (depending
on the acquisition capabilities of the receiver) and the corresponding Rate of change of TEC
(ROT) values can be calculated by dividing the dTEC values for the considered time-interval.
