DOWR time

DOWR time error versus UTC during 3 days in May, 2019

 

  • GPS L1 receiver
     
  • Standard outputs: 1PPS, 10 MHz, NTP, IRIG-B
     
  • Low 1PPS jitter: ± 2 ns
     
  • White Rabbit output for sub-ns time distribution over optical fiber across a building
     
  • In-factory calibration of timing delays for the provided GNSS antenna and cable (calibration error < 2 ns)
     
  • Total timing error at the end node < 15 ns under mild ionospheric conditions
     
  • Timing integrity monitoring of the GPS navigation message
     
  • Raw GPS data logging in daily RINEX files, for calculation of precise antenna position and for legal traceability to national UTC laboratories
     
  • Web-based configuration and monitoring
     
  • Remote monitoring and alarms via SNMP
