Abstract Each Satellite Navigation System (SNS) is comprised of three segments: satellite constellation, ground-control/monitoring network, and user receiving equipment. All satellites broadcast different navigation data messages at different rates. A detailed comparison of the messages of two SNS actually operational, GPS and GLONASS and one SNS under construction, Galileo, is presented in the paper. The transmission of data and differential corrections, raw measurements or position solutions from or to the user receiver can be based on various means of communication. Three formats, RTCM, RINEX and NMEA in different versions, internationally accepted and generally supported by all receiver manufacturers, have been specified for the exchange of satellite navigation data. The comparison of these formats is also presented.
