Product Description

GB8005

RACK-MOUNT HIGH PRECISION BEIDOU/GPS NTP TIME SERVER

The industrial grade BEIDOU/GPS Network Time Server that GFUVE GROUP 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 BEIDOU or GPS, and the precision of time is 20ns.The facility is secondary developed with the Beidou or GPS receiver that made by the special factory. It can track 12 Beidou or GPS satellites at the same time, and selects the best satellite automaticly for locating and timing.It outputs UTC time ,and the synchronous precision is 1µs.The GB8005 is quite cost effective and high quality,its highest record of MTBF is 15 years. The GB8005 time synchronization system device provides accurate synchronization time signals to various power system automation devices by using the second synchronization signal and time information message sent by Beidou navigation system and GPS( Global Positioning System) satellite.

FEATURES

1U Frame structure , 19 inch standard chassis, easy installation and maintenance.

All signal input and output interfaces are photoelectric isolation measures, safe and reliable.

Software interface can be set in English and Chinese, time zone can be set, panel with keys, easy to operate.

All-weather signal coverage, independent two-star system each other to ensure a long continuous high-precision timing.

High performance, wide range switching power supply, AC-DC compatible input, convenient and reliable, stable operation.

Providing programmable pulse, can be set for PPS,PPM,PPH; to provide setable frequency output, can be set to 100 K,1M,2M,5M,10M output, flexible and convenient.

Multiple 32-bit high-speed microprocessors + large-scale integrated FPGA chips, parallel high-speed data processing and various codes, excellent performance.

GPS, BD, CDMA three signal sources can be equipped with three options and two. especially suitable for electric power, machine room, hospital, etc.

Automatic selection of clock source according to priority, when receiving and decoding external IRIG-B (DC) code, automatic delay compensation correction technology is used to improve timing accuracy.

Separate 10 M/100M network ports (each port has a separate MAC address), flexible configuration, can be used in different sub-nets or different physical isolation networks, using NTP/SNTP protocols to provide time synchronization services.

High-precision punctuality frequency is derived from adaptive synchronization technology, closed-loop control punctuality technology to tame constant temperature crystal oscillator, to achieve long-time high-precision punctuality.

Having two PTP V2 high-precision timing ethernet interfaces while down-compatible with V1 protocols, telecom-level timing accuracy, support multicast and unicast transmission modes, and support the best master clock selection algorithm. (Optional)
