Precise Timing, Intelligent Collaboration -- Building Time and Frequency Infrastructure for Next-Generation Intelligent Transportation Systems
Beidou Bontec provides high-precision and high-reliability time synchronization and navigation and positioning solutions for the intelligent transportation field, covering intelligent networked vehicles (V2X), highway intelligent toll collection systems, high-speed railway communication and dispatching platforms and urban intelligent signal control. We build a safe and reliable time and frequency foundation through IEEE 1588v2 Precision Time Protocol (PTP), TSN deterministic network, anti-jamming GNSS positioning and combined navigation technologies. The product supports domestic software and hardware platforms to meet the demand for nanosecond synchronization and stable timekeeping for key applications such as automatic driving edge sensing, high-speed vehicle-road coordination, and unified scheduling of station control centers. Together with BDMonitor network-wide visualization platform, it realizes intelligent and distributed management of transportation infrastructure.

Intelligent Transportation Application Products
T770 Metrology-Grade Atomic Frequency Standard
The T770 is a metrology-grade rubidium atomic frequency standard, offering frequency stability, drift, and temperature coefficient up to 10 times better than ordinary rubidium clocks, and a one-day frequency stability comparable to that of a small cesium clock. It supports 1PPS and GNSS UTC synchronization, uses smooth frequency division to ensure a stable time base, and automatically maintains time in the event of a loss of lock. It features anti-interference algorithms and outputs multiple signals, including 10MHz, 5MHz, 1PPS, and Time of Departure (TOD). Options include 100MHz, 90MHz, and IRIG-B. Its 2U chassis makes it suitable for applications such as ePRTC master clocks, radar, communications, metrology, and aerospace measurement and control.
T760 GNSS Rubidium Atomic Time and Frequency Standard
The T760 is a high-precision GNSS disciplined rubidium atomic frequency standard. It integrates GNSS, a rubidium clock, and a low-phase-noise crystal oscillator, achieving output frequency stability comparable to that of a cesium clock. It supports 1PPS and UTC synchronization and features automatic timekeeping, frequency smoothing, anti-interference, and encryption. It runs a built-in Linux system and is compatible with PTPv2.1, NTP, and SNTP protocols, achieving nanosecond-level network timing accuracy. Housed in a 2U chassis, it supports multiple signal outputs, including 10MHz, 1PPS, IRIG-B, and Time of Departure (TOD).
T710 GNSS Rubidium Atomic Frequency Standard
The T710 GNSS Rubidium Atomic Frequency Standard integrates a GNSS receiver, a Rubidium atomic clock, and a low-phase-noise crystal oscillator. Using digital phase-locking technology, it outputs a high-precision 10MHz frequency signal with frequency stability comparable to that of a standard cesium clock. It supports 1PPS and UTC synchronization, features smooth frequency division and anti-interference capabilities, and automatically switches to the Rubidium clock if GNSS lock is lost. Supporting multiple signal outputs, including 10MHz, 1PPS, and Time of Departure (TOD), it is suitable for high-reliability applications such as radar, communications, power generation, and metrology calibration.
