Low Cost Mini IRIG B Time Server

The Synch(SY-M-1-RIG) Industrial Grade Mini GPS IRIG-B Server that we manufactured are specifically for electric power system, automatizatio system, telecom system,CCTV and traffic system that need high-precise time requirer.Our system is based on GPS, and the precision of time is 1us.The facility is secondary developed with the GPS receiver that made by the special factory of United States. It can track 12 GPS satellites at the same time, and selects the best satellite automaticly for locating and timing.It outputs IRIG-B time ,and the synchronous precision is 1µs.The SY-M-1-RIG is quite cost effective and high quality,its highest record of MTBF is 12 years.


  • Receiving frequency:1575.42MHZ, it can track 8-12 GPS satellites at the same time.
  • Antenna radio sentivity:-166dbw, with 30 metres wire. If the wire is not long enough, customer can prolong it by himself by selection of coaxial-cable that attenuation of 1.56GHZ is not more than 0.7db per metre, the attenuation of prolonged cable is not more than 5db.
  • Time Accuracy: Irig-B: 1us
  • Capture time: from 20 seconds to 2 minutes
  • (Annotate: the outputs of synchronous clock are all isolated by photoelectricity coupling and output 60ns)
  • Time code output: 1 channel of RIG-B(BNC Connector)+1 channel of 1PPS+1 channel of RS-232 or 485.
  • Low cost: Cost is just half of 1U size master clocks,very economical.
  • GPS antenna & software free: We offer free 30m GPS cable with antenna.
  • Small size: Can be portable to anyware and can be mounted to any place.
  • Low freigth cost: Because of small size and weight, the freight charge of it is just 50% of 1U size master clock.


  • Accurate universal atomic clock reference.
  • Far lower cost than competing products.
  • Ideal for closed or secure networks.
  • Automatic GPS lock and time sync.
  • Extremely compact design(Dimension: 15.8x14.6x6.0CM)
  • Indoor location (GPS antenna on a window).
  • Integral watchdog for long-term reliable operation.
  • Rack, wall mount.
  • Work temperature: -20 to 75C.
  • Very low power use.
  • 5 years warranty


  • Substation Automation
  • Video Surveillance(CCTV system)
  • Intelligent Traffic System
  • Telecommunication
  • Other fields that require high time accuracy
