Embodiment Construction
[0049] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0050] A calibration method for a ship's reference inertial navigation system in the present invention includes two processes of configuring equipment and implementing:
[0051] 1. Configure the following equipment:
[0052] (a) An auxiliary inertial navigation system with the same accuracy as the reference inertial navigation system
[0053] The auxiliary inertial navigation has an azimuth reference mirror and a reference plane, and is installed on the deck; in this specific embodiment, the auxiliary inertial navigation can adopt another set of reference inertial navigation;
[0054] Use the theodolite to measure the angle between the normal of the auxiliary inertial navigation azimuth reference mirror and the bow and stern lines; the position of the theodolite erection should be able to aim at the azimuth referen...
