Survey grade LiDAR mapping system, featuring precision LiDAR and Fiber Optic Gyro (FOG) IMU.



  • The new AL3-16 system is a weight optimized version of the AL2. By removing the aluminum enclosure, misc mounting brackets and stainless steel hardware, we've reduced the weight by almost 2.5kg! The AL3-16 is light enough for most medium sized UAV's, i.e. the DJI M600 and Alta 6/8.

    By separating the IMU/sensor from the CPU, GPS, Wifi and power distribution electronics; we've made integration easy for all different types of UAVs, ATV's, cars/trucks and even backpacks!

    Options include:

    • Satellite constellation support: GPS dual-frequency, GLONASS dual-frequency (optional), Galileo single-frequency (optional, dual-frequency available), BeiDou single-frequency (optional, dual-frequency available). Some options are field-upgradeable
    • Optional heading receiver for fast alignment
    • Features the KVH Fiber Option Gyro
    • 2.4 GHz WiFi, 5GHz WiFi and 3G/4G cellular network communication options

    Other external sensors such as the Multispectral Tetracam can be integrated using the 16pin I/O connector, which also supplies protected 5V and 12V power.

    The AL3-16 is light enough that the DJI S1000 multirotor can lift the sensor for approx 10 minutes and the ALTA 6 Freefly can fly for approx 15 minutes and the Alta 8 flys up to 25 minutes on a single charge!. These types of aerial platform are ideal for scanning areas up to one square kilometer.

    The AL3-16 includes the Velodyne VLP-16 Puck Lite high definition LiDAR sensor. The VLP-16 Puck Lite sensor provides 300,000 scan points per second. For more data on the sensor, please view specs on the specification tab.
