1. An aircraft position control system to make a position of an aircraft follow movement of a target landing point due to motion, the aircraft position control system comprising:
a processor, wherein
the processor is configured to
estimate a motion quantity of the target landing point, based on attitude correction acceleration obtained by correcting acceleration of the aircraft and based on a relative position between the aircraft and the target landing point;
output a target relative position between the aircraft and the target landing point to be achieved and target relative velocity between the aircraft and the target landing point to be achieved, based on the estimated motion quantity; and
control flight of the aircraft based on the output target relative position and the target relative velocity.
