Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Modification of the Genetic Algorithm in the Correction Scheme of the Inertial Navigation System in Autonomous Mode A.D. KUZNECOVA, I.V. MURATOV The problem of correction of the inertial navigation system of an aircraft in the conditions of the disappearance of the signal of the satellite navigation system is considered. In the correction scheme of the autonomous navigation system, a genetic algorithm is used to build a model of system errors. To increase the accuracy and reduce the model building time in the genetic algorithm, the weight function and the “shaking” operation are additionally used. The simulation results demonstrated the effectiveness of the used modifi cations of the genetic algorithm in the problem of inertial navigation system correction in autonomous mode. Keywords: aircraft, inertial navigation system, autonomous mode, errors, correction, genetic algorithm. DOI: 10.25791/pribor.7.2023.1424 Pp. 18-27.
