Web2.1. Dual-Frequency Model of Ionosphere The use of two-frequency GNSS stations allow to calculate the STEC (Slant Tec) which is the integral of the electronic density along the path of the signal be-tween satellite and receiver. There are three techniques for measuring total electronic content (TEC): io-nospheric soundings, radar and GNSS.
