Pandar128 boasts:

  • Resolution: up to 0.1° (H) * 0.125° (V) at 10 Hz refresh rate
  • Up to 6,912,000 points/sec
  • Detection capability: 200 m (10% reflectivity target)
  • High reflectivity accuracy and precision
  • Higher ingress protection rating: IP6K9K

Pandar128 represents a massive leap in performance over existing mechanical LiDAR sensors. It offers the finest horizontal resolution (up to 0.1°), 1.5x the total points produced by other available 128-channel LiDARs, and has a detection capability of 200 meters @ 10% reflectivity. This unrivaled measurement frequency and distance enable superb perception over an extended range, providing autonomous driving systems with longer reaction time critical for safe operation at medium-to-high driving speeds.

Pandar128 is designed with several other noteworthy improvements. It offers a higher level of ingress protection (IP6K9K), ensuring reliability in all weather conditions. Additionally, Hesai’s proprietary, industry-leading interference rejection feature has been further refined, reducing the noise rate.

Despite comprising twice the number of beams as Hesai’s Pandar64, Pandar128 retains a small form factor: it is just 7 mm taller and weighs only 1.63 kg. Pandar128’s compact design allows for seamless integration into a vehicle’s exterior for a more aesthetic configuration. The new system architecture also minimizes power consumption, requiring a maximum of 27 W (10 Hz), despite the massive data volume.

Most notably, Pandar128 is designed for automotive volume production. It has gone through comprehensive testing and is embedded with several innovative features, such as self-diagnosis for each beam. The sensor data is also encoded to safeguard against data misrepresentation or falsification. Referencing the full array of international automotive standards at the component, product, and process-level, Pandar128 has been meticulously scrutinized and optimized from the ground-up to ensure user safety, system integrity, and reliability.
