Rotary inertial navigation system heading error evaluation and compensation method, device and electronic equipment

Abstract

The invention provides a heading error evaluation and compensation method, device and electronic equipment of a rotary inertial navigation system. The method performs a first analysis and processing operation on the latitude error of the rotary inertial navigation system in real time based on preset error factors to obtain a first processing result, and performs a second analysis processing on the heading error of the rotary inertial navigation system in real time based on preset error factors operate to obtain a second processing result, perform a third analysis processing operation on the first processing result and the second processing result, obtain a correlation result of the heading error and the latitude error, and use the latitude error to evaluate the rotation based on the correlation result The heading error of the inertial navigation system. The invention can evaluate and compensate the heading error of the inertial navigation system in real time, and greatly improves the heading accuracy of the ship's inertial navigation system.

Description

technical field [0001] The invention relates to the technical field of rotary inertial navigation systems, and in particular, to a heading error evaluation method, compensation method, device and electronic equipment of a rotary inertial navigation system. Background technique [0002] The attitude information of ship inertial navigation is the reference information before the missile is launched, and the attitude accuracy of ship inertial navigation directly affects the use of ship missiles, radars and other weapon systems. It has become the high-precision standard navigation equipment for foreign ships. Under the dynamic conditions at sea, affected by factors such as sea conditions and ship motion, the attitude of the ship is constantly changing. The inertial navigation system of the ship that works continuously for a long time is affected by various error factors, and its attitude accuracy is continuously reduced. It greatly affects the combat effectiveness of the ship's...
