The invention relates to a microtype magnetic-infrared pose measuring system, comprising three-axis orthogonal infrared horizon, three-axis orthogonal magnetic strength meter, microprocessor and power supply manager; the three-axis orthogonal infrared horizon measures the to-ground pitching and rolling angle signals of a carrier; the three-axis orthogonal magnetic strength meter measures the components of the geomagnetic strength in X, Y and Z axes; combined with the measured pitching and rolling angles, it calculates the course angle of the carrier; it can measure of the all-pose information of the carrier, solid-structured, small-bulk, simple- algorithm, light and low-cost. It can work day and night. The used sensors can adopt the integrated MEMS chip integrated packaging technique, making it smaller. |
