The embodiment of the invention provides an aircraft track calculation method based on stage coordinate system transformation. The method comprises the following steps: setting task parameters, and setting a driving plan of a ship, a route point set of an aircraft task execution stage and a standard route point set of a recovery landing stage; setting an absolute coordinate system and a relative coordinate system; the method comprises the following steps: calculating a flight path in a takeoff stage, recording a current position of a ship as an original point of a relative coordinate system when the aircraft takes off, initializing position information of the aircraft, and calculating a corresponding distance of the aircraft flying at a set speed within a set time interval based on the relative coordinate system; converting latitude and longitude coordinates of the aircraft in a relative position absolute coordinate system according to the real-time position of the ship; transition from a take-off stage to a task execution stage is carried out; calculating a task execution stage track; transition from a task execution stage to a recovery landing stage is carried out; and calculating the flight path of the recovery landing stage, and determining the flight segment of the recovery landing stage of the aircraft, so that the aircraft lands on the ship.
