NAVIOR-CSM
NAVIOR-CSM - the single board, full-featured, 32-channel navigation receiver operating on signals:
  • GLONASS L1, С/Т code;
  • GPS L1, C/A code;
  • GALILEO/COMPASS L1, OS code;
  • SBAS L1.

NAVIOR-CSM is the base for building consumer navigation equipment:

  • monitoring system of road and rail transport;
  • navigator;
  • sea navigation equipment;
  • system synchronization and accurate time.

NAVIOR-СSM

NAVIOR-CSM provides compatibility with the receiver navigation NAVIOR-24 CH-4701 (discontinued) by overall and mounting dimensions. Application NAVIOR-CSM receiver instead NAVIOR-24 does not require the revision of the consumer hardware and software equipment and it provides better specifications (including - for accuracy, time of receipt of the decision, power consumption, operating temperature range).

Functions and features

The receiver provides a continuous solution of the following tasks:

  • receiving and processing signals of GLONASS, GPS, GALILEO / COMPASS, SBAS on open civil codes СT, C/A and OS in the range of L1;
  • automatic determination of the parameters: latitude, longitude, altitude, current time, course and speed;
  • automatic evaluation of the accuracy of navigation;
  • receiving, storage and update almanacs SNA;
  • exchange of information with external systems using NMEA 0183 (IEC 1162) or binary data BINR (proprietary binary protocol);
  • receiving and registration of correcting information in accordance with the recommendations of RTCM SC 104;
  • forming 1 PPS.

The receiver provides a measurement of the navigation parameters in terms of the dynamics of the object:

  • speed up to 500 m/s;
  • height up to 18 000 m;
  • acceleration up to 50 m/s2.

The receiver is on the circuit board of 50×75 mm.
