A method, apparatus, medium, device and product for estimating a state of an aircraft

Abstract

The application relates to the technical field of aircraft navigation control, and particularly provides a method, device, medium, equipment and product for aircraft state estimation, which can comprise the following steps: acquiring an initial state variable of an aircraft; updating the initial state variable by using the motion acceleration of the aircraft in a navigation coordinate system to acquire updated state data; wherein the updated state data comprises an updated state variable and an error covariance matrix corresponding to the updated state variable; correcting the updated state data based on external observation data to obtain target state data of the aircraft; and the target state data comprises a target state variable and a target error covariance matrix. The application can improve the accuracy of aircraft state estimation.
