Long 155mm x 128mm x 176mm

Weight

905 ± 5 grams

System Power Consumption

28 W (typical) / 58 W (max)

Protection GradeIP54

Supported Models

Longitude and latitude M300 RTK (requires use with DJI RC Plus)
Matrice 350 RTK

The above data represents typical values. Test conditions: flat target, target size larger than the diameter of the laser beam, atmospheric visibility of 23 kilometers, laser vertical incidence. Additional note: The range is shorter on sunny days compared to cloudy days; if a laser beam hits more than one target, the laser pulse energy is dispersed, which may reduce the measurable distance; the measurement range ends at 500 meters.

Point Cloud Data Rate

Single EchoUp to 240,000 points/second
Multiple EchoesUp to 1,200,000 points/second

System Accuracy

Flatness Accuracy:5 cm @ 150 m
Elevation Accuracy:4 cm @ 150 m

DJI Outdoor Test Site, under the following conditions: Zenmuse Mounted on Matrice 350 RTK and powered on, plan the surface route using DJI Pilot 2 (with IMU calibration enabled), in duplicate scan mode, with RTK status as FIX, relative flight altitude of 150 meters, flight speed of 15 m/s, gimbal pitch at -90°, no straight line segment exceeding 1500 meters in the route, distinct edge features of ground objects, and using bare, hard check points that comply with the diffuse reflection model. Post-processing with DJI Terra, with point cloud precision optimization enabled during processing. Under the same conditions, without point cloud precision optimization, elevation accuracy is 4 cm, and planimetric accuracy is 8 cm.
