Technical Characteristics of Differential Transmissions for Global Navigation Satellite Systems from Maritime Radio Beacons in the Frequency Band 283.5-315 kHz in Region 1 and 285-325 kHz in Regions 2 and 3
Many Administrations have implemented transmissions from radio beacon stations of differential corrections for global navigation satellite systems (GNSS). This Recommendation contains the technical characteristics to which such transmissions should conform for corrections to the GPS and GLONASS Navigation Satellite Systems. The Recommendation also describes the various types of differential correction messages used for those navigation satellite systems and the message format. In addition, it contains details of message transmission schedules.
