Total Electron Content Products


Total Electron Content over Europe TEC

Product Description:

    2-D plot showing the recent conditions of ionospheric Total Electron Content over Europe that impact GNSS-derived position accuracy. Vertical TEC and equivalent range error at L1 frequency (1.575 GHz) are shown together with related TEC products such as 1 hour forecast, medians, spatial gradients and TEC rate of change. This ionospheric product is designed to estimate the signal delay for single frequency GNSS applications.

Target Users:

   Product is addressed to academic, governmental and commercial users, in particular to customers of single frequency RF technologies in positioning and remote sensing.
