The Hesai AT128P is a 128-channel, automotive-grade hybrid solid-state LiDAR for long-range forward perception. Its 1-D rotating-mirror architecture images a 120° × 25.4° field of view as a regular 1200 × 128 point cloud, ranging 210 m at 10% reflectivity (0.5–260 m instrumented) with ±5 cm typical accuracy and 3 cm precision (1σ). As the production successor to Hesai's widely deployed AT128 ADAS platform, it brings series-automotive sensing quality to development and integration work.

With selectable 10/20 Hz frame rates, the AT128P streams 1,536,000 points per second in single return — twice that in dual return — at a finest far-field resolution of 0.1° (H) × 0.2° (V). Rated IP6K7 & IP6K9K with a 905 nm Class 1 eye-safe laser, a −40 °C to +85 °C operating range, 9–32 V input, and 1000BASE-T1 automotive Ethernet with PTP time synchronization, the 940 g sensor is built for autonomous-vehicle development, robotaxi and shuttle programs, high-speed outdoor robotics, mobile mapping, and intelligent transportation systems research.
