Course error evaluation and compensation method and device for rotary inertial navigation system and electronic equipment

Abstract

The invention provides a course error evaluation and compensation method and device for a rotary inertial navigation system and electronic equipment. The method comprises the steps of executing a first analysis processing operation on a latitude error of the rotary inertial navigation system in real time based on a preset error factor to obtain a first processing result; performing second analysisprocessing operation on the course error of the rotary inertial navigation system in real time based on the preset error factor, and obtaining a second processing result; executing third analysis processing operation on the first processing result and the second processing result to obtain an association result of the course error and the latitude error, and evaluating the course error of the rotary inertial navigation system by using the latitude error based on the association result. The course error of the inertial navigation system can be evaluated and compensated in real time, and the course precision of the ship inertial navigation system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of rotary inertial navigation systems, in particular to a heading error evaluation method, compensation method, device and electronic equipment of a rotary inertial navigation system. Background technique [0002] The ship inertial navigation attitude information is the reference information before the missile is launched. The accuracy of the ship inertial navigation attitude directly affects the use of ship missiles, radar and other weapon systems. At present, the rotary inertial navigation system (that is, the rotary inertial navigation system) has been It has become a high-precision standard navigation equipment for foreign ships. Under dynamic conditions at sea, affected by factors such as sea conditions and ship movement, the attitude of the ship is constantly changing. For the ship inertial navigation system that has been working continuously for a long time, its attitude accuracy is continuously reduc...
