True Terrain Following kit for DJI drones (radar altimeter)

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

• software,
• SkyHub onboard 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.
