Server Video Introduction
T600-BD NTP time server independently developed by Beijing Beidou Bangtai, with 1 microsecond synchronization, 50,000 times/second concurrency, supporting 2 million terminals online at the same time; six Gigabit network ports + Bonding load balancing, MD5/State secret double encryption, financial and national defense level security; full constellation GNSS + 300 m antenna, -10 ℃ ~ +55 ℃ industrial operation, 1U rack. Plug and play; VFD screen + dry contact alarm.
The T710 GNSS rubidium atomic frequency standard consists of a high-precision GNSS receiver, a high-performance rubidium atomic clock, a low-phase-noise phase-locked crystal, a control module, and a low-noise amplifier module. Through the digital phase-locking technology, combined with the long-term stability of GNSS, the low aging of rubidium clock and the high short stability of constant temperature crystal, it realizes the atomic frequency standard with low phase noise and high accuracy.
T830 high-precision clock server is designed for financial, securities, futures high-frequency trading, equipped with high-sensitivity anti-jamming domestic BeiDou receiver, supporting external cesium clock ePRTC timekeeping, compatible with BeiDou, IRIG-B, PTP, 1PPS + TOD multi-reference input. At the same time, it provides 10G/1G fiber optic interface, and the timing accuracy meets the strict trading timing requirements.
The T840 Carrier Grade Clock Server is designed to meet the stringent requirements of new mobile, fixed-line and wireline networks, where reliable and accurate synchronized transmission is critical from the core network to the edge network, meeting user requirements for high accuracy, security, complex network deployments, and stringent regulation.
T-ASJ10 GNSS deception interference safety protection equipment adopts advanced anti-spoofing interference technology, which can effectively detect and identify the deception interference signal, and quickly shut down and isolate the abnormal signal to eliminate the influence of deception interference.
FT91 is a high-performance frequency comparator specially designed for high-performance atomic clock testing, which can realize 1-30MHz arbitrary frequency point measurement, and the additional stability of the measurement can reach 1.2×10-13 at 10MHz. Moreover, this module integrates a high-performance special clock internally, which does not affect the performance of the actual measurement in the case of any frequency difference between the measured and standard signals.
Program Analysis Video Presentation
GNSS Spoofing Jamming Enhanced Security Solution
In critical infrastructure, time is order. Clock servers are usually GNSS-based, but spoofing and jamming can lead to time jumps and false grants, posing serious system risks.
Time and Frequency Practice
Satellite signal loss troubleshooting process
Sudden loss of satellite signal, REF blue light off, ALM red light on? This is one of the common alarms for timing.
NTP server installation and use tutorial
This video takes you to a complete understanding of the installation and use process of Beijing Beidou Bontec NTP server.
NTP Mini-Classroom
A minute to show you the core difference between NTP and regular servers
Today we're going to talk about a fundamental protocol that underpins the entire Internet, but has been overlooked - NTP.
How does a Linux server synchronize time with an NTP server?
This video focuses on a configuration demonstration to help you quickly understand how Linux time synchronization is implemented.
How does the switch synchronize time with an NTP server?
The video in this issue covers device login and time synchronization configuration, to operational state verification and configuration saving.
NTP status normal time but not synchronized?
In this video, we'll troubleshoot why the NTP status clearly seems normal, but the time just won't synchronize, based on real customer cases.
Who invented NTP? Why is NTP still widely used after more than 40 years?
A protocol that was born in 1985 and is "older" than many Internet users, but still quietly calibrates devices around the world every day for NTP.
How is the NTP time deviation calculated?
This video will use animation to completely disassemble the NTP core algorithm, showing how NTP can complete accurate clock synchronization in a jittery network with only four timestamps (T1,T2,T3,T4).
