A method of improving the navigation system performance parameters with the use of ground functional add-ins in respect of radio signal extension properties in the air is considered in the article. The total electron content values broad- cast, determined by double-frequency measurements allows to transmit correction data by all available types of GLONASS and GPS navigation signals, keeping within standard information transmitted content, regulated by ICAO, that would have been impossible with the use of standard methods of correcting information broadcast. Due to the increased number of the used navigation signals operating availability of GBAS improves. It is possible to use corrections, measured by a ground station for a pair of signals in different frequency bands (for example L1OF and L2OF) for more accurate positioning on other navigation signals (L2OC). It is also possible to broadcast the differential corrections for all available types of naviga- tion signals GLONASS and GPS and remain in a standard volume of transmitted information, which is regulated by the International Civil Aviation Organization.
