Time & Synchronization

Hesai lidar supports multiple methods for achieving precise time synchronization.

Synchronize Time using PTP

Use Precision Time Protocol to achieve precise time synchronization among multiple sensors

Synchronize Time using GPS

Use the GNSS_NMEA protocol (GPRMC or GPGGA) with an external clock source to obtain absolute time

Synchronize Azimuth Angle

Control the lidar to rotate to a specified azimuth at the whole second moment, enabling real-time angle and data synchronization with other sensors
