The invention relates to a double-ring guidance method of skip re-entry, and belongs to the field of the guidance of the re-entry of aircrafts. According to the double-ring guidance method disclosed by the invention, the control precision of the guidance method to terminal distribution is improved by utilizing the prediction-correction executed by slow guidance tasks, and the problem that the control demand of high precision of skip re-entry is difficult to satisfy by only using the standard trajectory method is solved. According to the double-ring guidance method disclosed by the invention, the problem that the control precision of fall points is reduced by only using a prediction guidance method after the navigation precision deteriorates under large dynamic conditions is solved by utilizing a standard trajectory tracking method executed by fast guidance tasks. The prediction-correction executed by slow guidance in the double-ring guidance scheme disclosed by the invention solves the problem of the control precision of the secondary re-entry section under the conditions of initial large distribution.
