WebIonospheric delay of a microwave signal depends on its frequency. It arises from ionized atmosphere (see Total electron content ). This phenomenon is known as dispersion and can be calculated from measurements of delays for two or more frequency bands, allowing delays at other frequencies to be estimated.
