The BeiDou Satellite Navigation System, a source of national pride, is familiar to everyone. The precise timekeeping provided by BeiDou in conjunction with 5G ensures our alarm clocks ring on time in the morning; the optimal route recommendations and countdown timers at traffic lights on map software rely on BeiDou's precise positioning and navigation; even the ticket-grabbing process for concerts depends on the precise timing service provided by BeiDou... BeiDou has gone from being 'on the horizon' to being right beside us.

This year marks the 30th anniversary of the BeiDou system project launch, As an important time-space infrastructure independently constructed and operated by China, BeiDou has now achieved global networking, providing all-weather, all-time, high-precision positioning, navigation, and timing services. Various   "BeiDou+" and "+BeiDou" new models and new industries are booming. Far East Communications has developed a number of timing, navigation, positioning, and direction-finding devices based on BeiDou system applications, which can be widely used in various fields such as communications, power, navigation and control, and rail transit, providing strong support for the implementation of the BeiDou system.

BeiDou Disciplining, Highly Stable Timekeeping
 

This module incorporates a high-stability SC cut crystal oscillator and a high-precision fast disciplining circuit independently developed by Far East Communications. After being disciplined by the BeiDou system timing signal, it can generate high-precision PPS clock synchronization signals and high-accuracy 10MHz frequency signals. Thanks to the self-learning high-retention algorithm during the disciplining period, this module can still output an error accuracy of 1.5μs/24h   PPS local clock signal.

Application Areas: 5G mobile communication base stations, intelligent transportation, power monitoring, etc.

BeiDou Timekeeping, Precise Clock
 

This device has PPS, B-code, NTP/PTP, etc.   multiple timing methods, After receiving the BeiDou system timing signal, it can quickly achieve frequency calibration and time synchronization of the local clock, outputting a timing accuracy of 10ns local clock   signal. When   the BeiDou signal is lost, it can provide a precise clock signal to the system through the high-retention function.
 

Application Areas: Satellite navigation and control, smart grid monitoring, rail transit, finance

BeiDou Positioning, High-Precision Navigation

 
This device has both navigation and timing functions, equipped with a high-performance navigation receiver, using the BeiDou system's average global measured positioning accuracy of 2.34 meters, it can achieve high-precision positioning, direction-finding, and navigation, with a direction-finding accuracy better than 0.1°/2m baseline. At the same time, this device supports BeiDou high-precision timing function, which can provide various time-frequency signals to the terminal system.
Application Areas: Satellite communication and navigation, radar control

Relying on the rich resource advantages of the BeiDou system and combining a deep understanding of the application of time-frequency technology, Far East Communications will continue to accelerate the research and development and production of BeiDou application terminal equipment, contributing to the construction of innovative application scenarios of "BeiDou+" and "+BeiDou", empowering the digital transformation and upgrading of industries, and injecting new impetus into the high-quality development of China's digital economy.
