Astronomical Clock introduction and selection
In the rapid scientific and technological progress and rapid economic development, all areas of precision time service equipment, stability, portability and put forward higher requirements, so when the clock mode and the type of grant has been steadily progressing, such as base stations timing, when the satellite time, a radio wave timing and the like. Astronomical Clock is a time clock award, is an astronomical clock from the observatory precision time clock to control the .
Astronomical clock means receiving clock server GPS and Beidou satellite timing positioning signal, the clock server obtaining standard time information from the GPS and Beidou satellite, and, to the network device through the network transmission to provide accurate timing signal, the device NTP real-time correction when service, the server output clock 1PPS (second signal) and the serial synchronizing pulse signal tod time information.
Currently clock server on the market a lot, there are some other brands of agents, and aftermarket performance can not be guaranteed. And Xi synchronization Ltd is its own production, as SYN2151 type NTP time synchronization server, to GPS Compass and other timing signals as a reference, and provides time accuracy of 1 channel NTP network outputs can be extended to four network output, network output grant It is 0.5-10ms, support serial output signal outputting 1PPS pulse signals and the like. Wherein means NTP network time protocol to synchronize the computer time , when wide coverage to a million devices may be timing NTP network simultaneously grant, the amount of NTP Request> 14,000 / sec. SYN2151 type NTP time synchronization server, providing WEB, SSH encrypted communication parameter management software monitors and settings, provides SNMP network management function, using the latest NTP / SNTP protocol version when the time is accurate and reliable, and comes standard with built-in high-precision OCXO be defensive when rubidium atomic clock can also choose to tame temperature crystal module, tame rubidium clock modules, etc., so keep higher accuracy to ensure the accuracy of time.
Clock server to meet the theoretical research, scientific experiment, engineering and industrial production and other areas required for timing devices, but now the clock servers on the market still not enough and suppliers are many, such as Shanghai, Beijing, Guangzhou, Sichuan, Shenzhen , and other places have supplier, but less developed its own production suppliers, vendors and some agents of foreign products, some vendors no core technology, some vendor's products relatively simple, convenient aftermarket products led product performance immature core technology, product selectivity can only produce small devices can not provide test equipment timing, bring a lot of inconvenience in use.
Xi'an Electronic Science and Technology Co., Ltd. Synchronous Timing is a professional production equipment manufacturers, focusing on the time-frequency product nearly 10 years, product development, production and sales of its own, with nearly 1,000 square meters of production workshop, and independent research and development of technology to improve after-sales service, product performance stable and reliable after-sale convenience, but the brand has been registered in Xi'an synchronization, has received the title of high-tech enterprises, has been cooperative units, research institutes, military industrial enterprises, research institutes, schools, hospitals, power plants, factories and so on, to meet all walks of life demand.
