Embodiment Construction
[0019] like figure 1 Shown is the flowchart of the method of the present invention. The method of the invention uses the precise navigation information of the airborne inertial navigation to correct the navigation error of the MEMS inertial navigation.
[0020] The main steps of the inventive method are as follows:
[0021] (1) When the airborne inertial navigation information is valid, obtain the navigation information of the airborne inertial navigation, including the azimuth ψ of the carrier p , pitch angle θ p , roll angle γ p , according to the azimuth ψ p , pitch angle θ p , roll angle γ p Get the attitude matrix of the airborne inertial navigation Attitude Quaternion Q 0 .
[0022] The effective time of the navigation information of the airborne inertial navigation here refers to the time when the transmission of a frame of navigation attitude data transmitted from the airborne bus to the communication system in motion is completed.
