| The PX4 firmware does not support altering an ongoing mission. This requires a full clear of the mission. Afterwards the mission needs to be uploaded using multiple mavlink messages and roundtrip times (see [[https://mavlink.io/en/protocol/mission.html|Mission Protocol]]).\\ | The PX4 firmware does not support altering an ongoing mission.

This seems possible as no sudden deviation of the predicted route is to be expected for a ship. | + | * A predicted route of the ship could be used to generate a trajectory that passes though all points the landing spot could be located at.
