Comparaison entre un GPS standard et haute performance.
The primary difference between Headwall’s standard and high-performance GPS/IMU systems is accuracy of altitude, roll, pitch, and heading data
GPS/IMU ACCURACY AFFECTS LIDAR DATA CAPTURE & VISUALIZATION
When utilizing otherwise identical airborne platforms, the quality of the point-cloud data captured from the integrated LiDAR systems differs due to employing either the Standard (Gen 2) or High Performance GPS/ IMU.
Headwall highly recommends purchasing the High-Performance GPS/ IMU for LiDAR-equipped systems.
Note the clarity of the point-cloud image on the right, captured on a Headwall unmanned aerial vehicle (UAV) system equipped with the High-Performance GPS/IMU, versus the image on the left, captured on a system equipped with the Standard (Gen 2) GPS/IMU.
