СН – 3841М

Autonomous device of frequency-time synchronization СН-3841М produces high-precision time in the scale of world coordinated time on a sample (standard):

  • US (UTC US),
  • RF (UTC SU),
  • SNS GLONASS (UTC GLONASS),
  • GPS (UTC GPS).

 

Provides the following tasks:

 

  • continuous pulse signal 1PRS;
  • provides operation in the mode with known coordinates, using one NCA;
  • provides operation in the mode of coordinate averaging (with averaging over 24 hours);
  • provides work in the WGS-84 coordinate system or the user’s coordinate system.

The signal “1PRS” is issued on the RS422 port with an error not exceeding 100 ns.

 

Signal form:

  • pulse lasting from 25ns to 1,6ms;
  • pulse amplitude not exceeding 5V;
  • the front edge is synchronized with the UTC timeline;
  • the second edge corresponds to the leading edge of the pulse.

 

Specifications:

  • Operating temperature: + 5 ° C … + 50 ° C
  • Overall dimensions: 105x48x132mm
  • Weight: 0.45 kg
  • Power supply: (7 … 12) DC
  • Power consumption: not more than 9W
  • Interface: 2 RS422 ports
  • Exchange protocols: NMEA 0183 and BINR.
