We consider the possibility to enhance the functions of the Ukrainian geostationary communication satellite to realize the radiophysical method of measuring the Earth’s gravitational field parameters and improving the system of position and time determination. It is planned to use an EGNOS-type spacecraft as a functional adjunct to the spread of differential corrections in signals of the global navigational satellite systems (Galileo, GPS, GLONASS) and also as an element of high-precision synchronization of remote reference clock
Keywords: geostationary communication satellite, gravitational field, position and time determination
