Description:

СН-3836 signal synchronization unit is designed for synchronization of DECT telecommunication systems using signals from Satellite Navigation Systems GLONASS and GPS NAVSTAR. The unit ensures processing of noisy SNS signals and reliable operation in severe EMI conditions in urban and industrial areas. СН-3836 easily connects to the user equipment. It does not require additional configuring,
operates immediately after switching on. The unit is designed on the basis of singleboard recision time sensor GNSS NAVIOR.

Functions:

• Generation of pulse signal 1PPS, step 1 Hz, synchronized with UTC (default), GPS
• Generation of 2.048 MHz clock signal
• Continuous supply of 1PPS and 2.048 MHz round the clock
• Selection of operating system GLONASS or GNSS (GLONASS +GPS)
• Operation in the known coordinate mode, in so doing, one NKA is enough for synchronizing of the 1PPS signal
• Operation in the coordinate averaging mode with switching to the known coordinate mode after 24 hours of operation (using average coordinates over the 24 hours)
• Operation in the WGS-84 coordinate system (default) or in the user coordinate system
• Reception and account of differential corrections in compliance with guideline RTCM SC-104
