Embodiment Construction
[0073] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0074] like figure 1 As shown, the specific implementation steps of a navigation method based on the tight combination of polarization-geomagnetic vector of the present invention are as follows:
[0075] 1. The compound-eye-like polarization compass composed of polarization navigation sensors can obtain the sun vector in the coordinate system of the detection module in real time The schematic diagram of the compound eye polarized compass figure 2 As shown, the compound eye-like polarization compass consists of three polarization sensors, which are denoted as M 1 , M 2 , M 3 , where M 1 The observation direction is the zenith direction, M 2 and M 3 Symmetrically mounted on M 1 Measurement, the installation angle is η, with M 1 Establish a coordinate system Mxyz for the benchmark, the x-axis is the direction of the carrier body axis, the...
