GNSS Control and Correction Station "AKVA-Station-M" for Enhanced Navigation Accuracy

The control and correction station "AKVA-Station-M" is designed to control the integrity of the navigation field of GNSS GLONASS/GPS/GALILEO, the formation of correction information to the signals of GNSS GLONASS/GPS and control its quality. The "AQUA-Station-M" KSS realises the functions of a reference station, an integral control station and a control station. KKS "AQUA-Station-M" forms and broadcasts differential corrections for pseudodistance measurements to GLONASS satellites transmitting standard accuracy signals of L1 range and pseudodistance measurements to GPS satellites transmitting C/A signals of L1 range. Differential corrections are issued as messages 1, 9, 31, 34 in accordance with the requirements of RTCM SC-104 version 2.3. Additionally generated RTCM messages are message types 3, 4, 5, 6, 7, 16, 32, 33, 35, 36.
