True Terrain Following kit for DJI drones contains everything necessary to fly DJI drones at extremely low altitudes over terrain with high precision:

• software,
• SkyHubonboard computer,
• radar altimeter,
• training.

Many sensors require very low clearance between the sensor and surface – GPR, magnetometers, etc. Echo sounders require precise elevation over the water surface. True Terrain Following system for DJI drones allows automatic flights over the surfaces at very low altitude.
