Smart grids require widely distributed μs-level synchronization accuracy to ensure relay protection and new energy grid connection safety.

Challenges: Vehicle-road collaboration requires centimeter-level positioning and microsecond-level time synchronization, and needs to adapt to the extreme vibration environment on board.

Field environments require portable time and frequency equipment that is anti-interference and anti-vibration to ensure encrypted communications and radar precise positioning.

Challenge: ultra-dense base station deployment requires time synchronization accuracy <±100ns, and must be compatible with multi-vendor equipment.

Solution:

• Core technology: chip-level CPT atomic clock (±5ns accuracy) + PTP enhanced synchronization server (supporting 1588v2/TSN).

• Applicable products: 5G base station time and frequency module, high-precision synchronization gateway, network monitor.

• Scenarios: Open RAN architecture, millimeter wave base station, edge computing node.

• Customer value: base station deployment cost reduced by 25%, synchronization efficiency increased by 50%.

Challenge: Low-orbit satellite constellations require ultra-small, radiation-resistant, low-power onboard atomic clocks, and need to maintain nanosecond synchronization with ground stations.
