Example Embodiment
[0047] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.
[0048] In order to better understand the present invention, the following names are explained:
[0049] Inertial navigation (INS, inertial navigation system) is an autonomous navigation system that does not rely on external information and does not radiate energy to the outside. Its working environment includes not only air, ground, but also underwater. The basic working principle of inertial navigation is based on the laws of Newton’s mechanics. By measuring the acceleration of the carrier in the inertial reference frame, integrating it with time, and transforming it into the navigation coordinate system, you can get the value in the navigation coordinate system. Information such as...
