Triaxial satellite compass СН-4724
Satellite compass is designed for automatic continuous determination of:
  • the true azimuth
  • elevation angle
  • angle of roll
  • fix
  • altitude
  • UTC time scale

on the signals of satellite navigation systems GLONASS / GPS.

CH-4724 allows you to orient objects on the geographic poles, as well as on elevation angle and angle of roll.

Possible areas of application

  • orientation of the radar antennas and radio links;
  • construction;
  • sea and river transport;
  • aviation;
  • unmanned aerial vehicle (UAV);
  • in engineering instead of gyroscopes.

Functions and features

CH-4724 is a navigation apparatus, consisting of three antennas B-105 and goniometric unit. Antennas are placed in fixed locations at the facility with reference to the axis of object. The location of antennas should be capable of receiving signals from the area of the upper hemisphere. СН-4724 are provide:

  • determination of navigational parameters:
    • FIX;
    • true azimuth;
    • elevation angle;
    • angle of roll;
    • coordinates;
    • velocity;
    • data time in the scale UTC.

The scale UTC time is given as a 1PPS (1 ms pulse duration issued via RS-422) and digitizing the timestamp by using the PORZV;

  • external interface RS-232 by standard NMEA-0183 (IEC61162) messages GGA, RMC, GLL, ZDA, HDT, PORZV, POHPR
