CONTINUOUS NORTH-SEEKING APPARATUS AND METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2022/174831

A1

A continuous north-seeking apparatus and method, an electronic device, and a storage medium, relating to the technical field of inertial navigation. The apparatus comprises: a MEMS gyroscope array (100) comprising a plurality of coaxially disposed MEMS gyroscopes and used for continuously outputting measured angular velocity data of a plurality of positions in a rotating process; a MEMS accelerometer (102) used for obtaining acceleration data when the MEMS gyroscope array (100) produces horizontal displacement so as to obtain a true north included angle in a moving process according to the acceleration data; and a data processing module (103) electrically connected to the MEMS gyroscope array (100) and the MEMS accelerometer (102), separately, and used for receiving and processing the angular velocity data and the acceleration data so as to obtain a true north included angle in a horizontal displacement state or a horizontal-displacement-free state. The apparatus uses the high-precision MEMS gyroscope array (100) and can continuously seek north at multiple positions, and the problem that existing orientation devices are easily interfered by environment, large in size, high in cost and inconvenient to carry and cause an increase in north seeking time is solved.
