I've noticed two problems with one of our Phantom 4 pros. They may be unrelated, but they started at the same time.
1. On automatic take off from ground station pro the drone climbs to about 10 ft then cancels out of the mission. No warnings or errors. If I transmit the mission again, while it's hovering, it works just fine. Also, if I take off manually and then transmit the mission it works fine.
2. On return to home I'm getting a hard landing. Usually it should slow its decent gradually as it gets closer to the ground, but this is not happening.
We have two Phantom 4 Pros and this is only happening to one of them using the same flight plan and i-pad. This happens consistantly now in different locations where wind is not an issue.
What I've tried so far:
-Calibrate compass
-Calibrate IMU
-Re-calibrating the sensor cameras in DJI assistant 2
-Re-flash the firmware
-Re-install ground station pro
-Use different i-pad
See versions below:
-Assistant 2 for Phantom v2.0.8
-Phantom firmware v1.05.06
-Ground Station Pro v2.0.8
