NTP Servers

We can design the optimal and most secure NTP synchronization network solution according to the scale of your network. You can freely choose external time sources such as GPS, Beidou, GLONASS, or CDMA according to your needs. Even if your installation environment does not allow receiving external signals, we can still maintain accurate network synchronization through the phase-locked local rubidium atomic clock or high-stability crystal oscillator. In addition, we have a comprehensive network-wide monitoring software that can further ensure the security of your network synchronization.

PTP Precision Server IEEE1588

The IEEE-1588 Grandmaster Clock from BeiDou Bangtai supports PTPv2 and provides nanosecond-level time and frequency synchronization for your network environment. It can flexibly receive satellite signals such as BeiDou, GPS, and GLONASS. Compared with traditional time and frequency signal transmission methods, IEEE-1588 simplifies the process by using a Grandmaster Clock to synchronize the network, and then outputs various standard time and frequency signals such as IRIG, 1PPS, 10MHz, and E1.

Gnss synchronization server

The GNSS synchronized clock is equipped with an intelligent learning algorithm. During the process of taming high-stability crystal oscillators with GPS/BeiDou satellites, it continuously learns and stores the characteristics of crystal drift. In the event of abnormal satellite signals, the system can automatically switch to holdover mode. It can use intelligent correction algorithms to continuously provide highly reliable time and frequency signal outputs.

Universal Time and Frequency Module

The clock module adopts a highly integrated GPS/BeiDou dual-mode disciplined OCXO synchronous clock module with a constant temperature crystal oscillator. This module integrates Russian imported dual-slot constant temperature crystal oscillator OCXO and high-precision timing type GPS/BeiDou dual-mode OEM board. It uses large-scale high-speed FPGA integrated circuits as the main processing chip, and high-speed AD/DA chips and a high-precision time-frequency control algorithm based on a phase-locked loop to generate and send accurate and stable time and frequency signals (10MHz, 1PPS, TOD). The daily average accuracy of the frequency output is < 1E-12, and the real-time accuracy can reach 2E-10. The timekeeping accuracy is better than 1us/hour.

Rubidium

The rubidium atomic clock is composed of a rubidium quantum part and a voltage-controlled crystal oscillator. The frequency of the voltage-controlled crystal oscillator is multiplied and synthesized, and then compared with the transition frequency of rubidium atoms in the quantum system. The error signal is fed back to the voltage-controlled crystal oscillator to adjust its frequency, so that it is locked to the frequency corresponding to the energy level transition unique to rubidium atoms. The short-term stability of the rubidium atomic frequency standard can reach the level of 10^-12, with an accuracy of ±5×10^-11.

Secondary clock

The digital clock adopts a 3-inch or 5-inch light-emitting diode display unit (LED) to display time signals consisting of numbers. The color is black background and red letters, and the display format is "year: month: day: hour: minute: second: week". The option supports content such as "hour: minute: second" and "year: month: day: hour: minute: second: millisecond". The installation method is wall-mounted (default method), suspended, embedded, etc., which can be determined according to the on-site environment.

Information Safety

"Time and frequency technology is a major driving force for improving information security. Frequency standards and time synchronization devices are essential components of modern military electronic systems. The stability and accuracy of clocks directly affect the performance of key systems such as military communication, navigation, surveillance, electronic warfare, missile guidance, and identification of friend or foe. Modern military systems have higher requirements for clock accuracy, reliability, and complex operating environments."

Capital construction

Key industries and infrastructure today rely on precise, continuous, and reliable timing and positioning information (PNT), even in the absence of satellite signals. Precise timing and synchronization in applications such as communication clocks, precise process control, intelligent control, real-time systems, and other critical tasks are crucial. These applications cannot afford the risk of failure, and even subtle delays can affect normal business operations.

Data

Challenge: Globalization and Continuous Growth of Big Data As Alibaba expands its global presence, its data centers are now distributed throughout the world. As a leading brand in B2B e-commerce and the largest and most active online trading platform in the global international trade arena, Alibaba expects us to use the most accurate clocks to meet their rapidly growing business needs. With the increase in the number of devices connected as the business grows, the demand for clocks in the business is also increasing. Real-time proof shows that simply adding hardware to improve synchronization capabilities and accuracy cannot be infinitely expanded, presenting both opportunities and challenges for us.

Financial service

The People's Bank of China's Financial Security Risk Warning According to the relevant national departments, there is a security threat of "GPS spoofing" in civil GPS devices in China. "GPS spoofing" technology uses GPS signal simulation transmission devices to generate false signals to deceive GPS receiving devices, causing them to work under false signals and ignore correct satellite signals, which is a wireless attack method.

Secure access and control

Time servers are crucial but often overlooked devices. Security and access control systems are a part of our daily lives, yet we seldom pay attention to their complexity and the security of their system components, such as surveillance cameras, video servers, card readers, and management software, among others.

Secure access and control

Metrological testing

Deploying high-precision testing equipment is crucial for detecting components, sensors, and subsystems, particularly in increasingly complex electronic products. High-performance testing and measurement are essential for all operations, including design and development that require high-performance testing and measurement, manufacturing that demands speed and efficiency, and cost and risk management to ensure product quality and customer satisfaction.
