Product overview
SYN1618 The high precision astronomical time synchronization system is a high precision time frequency frequency standard equipment designed and developed by Xi'an synchronous Electronic Technology Co., Ltd., which receives the time and frequency information of GPS, GLONASS and Beidou two generation satellite system. It selects one of them as the time frequency reference of the high-precision phase-locked unit, tame the internal high-precision rubidium atomic oscillator, and produces the high-precision timing pulse (1PPS) signal and time information after taming the output 10MHz signal as a time reference.
Key word Astronomical clock, GPS astronomical clock, GPS astronomical clock, Beidou astronomical clock.
Product function
1) The device starts self checking and inspects the working condition. It can give prompt and fault alarm in real time.
2) The front panel of the device has a liquid crystal display, displaying time information and displaying contents of year, month, day, hour, minute and second.
3) The equipment can receive UTC from GPS/GLONASS/ Beidou two generation satellite.
4) The mode of timing is manual and automatic.
5) The device can rely on the atomic clock for a long time to keep accurate time.
6) The device provides UTC second pulse two channels, and time data serial port output.
7) The device has the function of power failure protection: the external battery input interface is provided, the battery is DC 24V to 32V, and the main power of the system adopts AC 220V 50Hz. When the main power supply is supplied, the battery power supply is in the state of saving electricity or waiting for automatic shutdown.
8) The device has monitoring functions such as panel display operation.
9) The device has the function of signal backup.
Product characteristics
A) High precision, fully automatic, unattended, maintenance free, low power consumption and high reliability.
B) The internal frequency source has tame function without calibration of frequency source.
C) The main signal input and output circuit adopts electrical isolation circuit, which is anti-interference and anti damage.
D) The output interface signals are complete, and the output signals can be flexibly configured according to users' needs.
E) Wide working temperature range can work steadily for a long time.
Typical application
1) National defense research;
