GNSS非连续定位对高超声速飞行器组合制导影响
The Influence of Discontinuous Positioning of GNSS on Integrated Navigation Guidance of Hypersonic Aircraft
摘要
Abstract
Hypersonic aircraft mainly use an Global Navigation Satellite System(GNSS)and Initial Navigation System(INS)for navigation and positioning.However,in navigation warfare environments,GNSS signals may be interrupted or positioning may be discontinuous due to electronic interference or changes with aircraft flight attitude,which has a significant impact on the final guidance accuracy of hypersonic aircraft.To address this issue,a Kalman filter integrated guidance method and re-tuning integrated guidance method with intermittent INS corrections method are designed and implemented,and the algorithm principles and implementation methods are introduced.Monte Carlo statistical analysis method is used for simulation comparison research,and performance characteristics and mechanisms of the two methods are analyzed.Results show that intermittent correction of INS can reduce the guidance accuracy of hypersonic aircraft from the 300 m level to the 20～40 m level,and compared with pure position velocity correction method of the re-tuning combination guidance method,filtering combination guidance method with intermittent attitude correction has higher guidance accuracy.This indicates that the indefinite correction of INS can still effectively improve the guidance accuracy of hypersonic vehicles in the case of discontinuous positioning by GNSS.关键词
