Abstract

The invention belongs to the technical field of inertial navigation, and relates to a calibrating method for a reference inertial navigation system of a ship. A method for calibrating a ship's reference inertial navigation system. First, the reference inertial navigation system is installed in the reference inertial navigation cabin; Calibrate the azimuth reference mirror and bow and stern markings on the auxiliary inertial navigation; then connect the auxiliary inertial navigation, reference inertial navigation and data acquisition device; then calibrate between the auxiliary inertial navigation and the bow and stern lines of the ship and the reference plane , carry out data collection and installation error identification, and finally carry out calibration compensation, and calculate the attitude value after calibration. The technical scheme of the present invention can smoothly output the navigation system of the reference inertial navigation system to the reference coordinate system of the ship, and does not need a special pier for the ship, and does not need a high-priced gyro theodolite device capable of finding north, but only needs a simple theodolite The device can save the calibration cost.

Description

technical field

[0001] The invention belongs to the technical field of inertial navigation, and relates to a calibrating method for a reference inertial navigation system of a ship. Background technique

[0002] The ship's reference inertial navigation system (hereinafter referred to as "reference inertial navigation") is an important device of the ship's navigation system. It can not only provide navigation information for ship navigation, but also provide navigation information for multiple subsystems of the ship. Radar control system, missile weapon system, artillery control system, etc. With the development of inertial technology, the ship's reference inertial navigation system has a tendency to develop from a platform-type inertial navigation system to an optical gyro inertial navigation system. The volume and weight of the system are reduced, the reliability is improved, and the cost price is reduced. At present, domestic ship reference optical gyro inertial navigatio...
