GPS NTP Time Servers

GPS NTP Time Server /SNTP Time Server (1U Rack)

GPS/BDS Time Server(GPS & BDS sources)(Cost Effective Model)

The Bueno SY series of GPS/BDS time servers are specifically for power system, automatizatio system, communicate system and traffic system that need high-precise time requirer.Our system is based on GPS or BDS(Beidou), and the precision of time is 1µs.It can track 12 GPS satellites at the same time, and selects the best satellite automaticly for locating and timing. It outputs 1PPS, 1PPM, 1PPH time pulse and UTC time ,and the synchronous precision is 1µs, and it can measure the industrial frequency, and outputs date, time, cycle clock, cycle,  clock  difference, safe running days, and so on through RS232 serial with two formats. It is selected to used by automatization facilities that need standard time in electric power system.The facility adopted the technology of the united of software and hardware, and made good use of the potential of GPS receiver, so it has some characters such as high security, strong function, high precision, good proportion of capability and price, operate conveniently and so on,and it can afford to the requirement of time synchronous in electric power system,automatization  system, communicate system and traffic system. With its extendly used, the development of some automatization technologies such as accident analysis, trouble range measurement and relay protection and so on will be promoted and improved greatly.

2  Technical parameter:

1. Receiving frequency:1575.42MHZ, it can track 8-12 GPS/BDS satellites at the same time.

2. 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.

3. Capture time: from  20 seconds  to  2 minutes (Annotate: the outputs of synchronous clock are all isolated by photoelectricity coupling and output 60ns)

4.1PPS output:

Timing varacity: 1µs                 Voltage: TTL voltage

Polarity: positive pulse               Pulse width: about 100ms

Impedence: 50 Ώ                    Channel number: 1

Fore edge: <20ns

5.1PPM: output:

Timing varacity:: 1µs                 Voltage: TTL

Polarity: positive pulse               Pulse width: about 100ms

Impedence: 50 Ώ                    Fore edge: <20ns

6.1PPH output:

Timing varacity:: 1µs                 Voltage: TTL

Polarity: positive pulse               Pulse width: about 100ms

Impedence: 50 Ώ                    Fore edge: <20ns

7.Cycle precision: ±0.001

8.Industry frequency clock:  the clock that is promoted by industry electricity is synchronous with standard clock when power is on.

9.Clock difference: that is standard clock minus industry frequency clock,synchronous time difference is zero,precision is 20 ms.

10.Longitude, latitude: where the electric power synchronous clock locates.

11.Display: 14 bits LCD display that includes cycle,date,time,longitude,latitude,industry frequency clock,clock difference (standard clock minus industry frequency clock).

12.RS232: output time code (year, month, day, hour, minute, second), industry frequency clock time(hour, minute, second), clock difference,cycle.

13.RS232: output “ST” format time code (selected by switching circuitry)

14.Power: DC110V, 10%, 15W. AC or DC other power supply is also accepted.

15.Size: standard 1 U Chasis.

16. Support Redundant GPS timing systems.

17. Optional output connectors: RJ45,DB9,Seral 485 terminal,Irig-B, BNC,Fiber ST & all other types of connectors.
