Embodiment Construction
[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0056] Such as figure 1 As shown, the specific implementation steps of a polarization autonomous integrated navigation method based on confidence in the present invention are as follows:
[0057] 1. In figure 2 The polarization sensor shown is installed on the carrier, and the module coordinate system is established based on the polarization sensor. The x-axis of the module coordinate system points to the right along the horizontal axis of the carrier, the y-axis points to the front of the carrier along the longitudinal axis of the carrier, and the z-axis points along the vertical axis of the carrier. Above the carrier, use N polarization sensors to obtain multiple polarization azimuth angles Then the polarization vector under the module system is as follows image 3 As shown, where E1...E10 is the polarization vector, its expression in th...
