in general pathfinder edge only outputs position data. to compensate the flight controller should only use the GPS like signal we are giving it for xy position. 

if you are flying close to the ground the drone should have range finders or other sensors to aid in its ability to determine in its heigh from ground

Pathfinder edge should not be used for following values

• Z position/height

• Drone heading

• Velocity (x,y,z)
