Problems solved by technology

[0003] In view of the current carrier (such as the hull) existing in the above-mentioned prior art, it runs very smoothly during navigation without large-scale steering, and the inertial navigation equipment on the carrier will not move substantially. Therefore, there are errors in the attitude information measured by the inertial navigation equipment, which makes the navigation information also have errors, which leads to the technical problem of providing wrong headings. At present, no effective solution has been proposed.

Description

technical field [0001] The present application relates to the technical field of attitude measurement and navigation, in particular to a vehicle attitude measurement system, method, device and storage medium. Background technique [0002] Existing vehicles (such as ship hulls) generally use inertial navigation equipment to measure the attitude of the vehicle, and then obtain the navigation information of the vehicle to perform navigation. However, when the inertial navigation equipment measures the attitude information, if the range of the attitude change of the vehicle is relatively small, there will be a large error in the measurement results of the inertial navigation. The current carrier (such as the hull) runs very smoothly during navigation, and does not produce large-scale steering. Therefore, the inertial navigation equipment on the vehicle will not move substantially, so that the attitude information of the vehicle measured by the inertial navigation equipment has ...
