DGNSS-RTK reference station

DGNSS-RTK reference station


Functions and features

  • Receive signals from satellites:
    • GLONASS frequency band L1 (CT-code, numbers lettered frequencies from minus 7 to plus 6);
    • GPS in the frequency range of L1 (C / A code);
    • SBAS in the frequency band L1.
  • Measurement pseudorange all of the received signals of GLONASS / GPS / GALILEO, synchronization of timing measurements to scale the system GLONASS / GPS;
  • Calculation of the differential corrections and the formation of correction information for navigation signals:
    • for ST-code satellites GLONASS;
    • for C/A-code satellites GPS (RTCM SC-104, v. 2.3, 3.1).
  • Working as a single base station RTK (DGNSS) and as part of a network base station RTK.
  • Reception, storage and updating of almanacs satellites.
  • Autonomous Integrity Monitoring (RAIM) with the functions:
    • detection of failure measurements;
    • avoid of failure measurement .
  • Communicate with external users via the RS-232, Ethernet, Wi-Fi in accordance with the communications protocol NMEA0183 (IEC1162), RTCM SC-104, NTRIP.
  • Forming message types 1, 3, 5, 6, 7, 9, 16, 18, 19, 31, 32, 33, 34, 35, 36, 37 in accordance with the standard RTCM 10402.3 - Amendment 1.
  • Forming message types 1001,1002,1005-1010, 1013, 1019, 1020 in accordance with the standard RTCM 10403.1 - Amendment 1-4.
  • Automatic monitoring of the functioning of the reference station.
  • Determination of the origin of the phase center of the antenna on a series of observations.
