The carrier-based aircraft system is the core component of modern aircraft carrier combat system,a maritime platform for carrier-borne fighters,whether carrier aircraft can demonstrate combat power depends on the ability of the carrier-based aircraft to take off and landing.In order to improve the safety and reliability of shipboard on warship,this paper aims at GNSS/INS/Photogrammetry integrated navigation theory,discussed from the basic level of integrated navigation system on implementation and the performance of the whole positioning.The mainly research is when satellite is not available,the inertial navigation error is corrected by the positioning of the Photogrammetry,to achieve high accuracy,high reliability and data refresh rate.The multi-rate kalman filter method is used to deal with the problem of the non-equal intervals between the INS and Photogrammetry.Finally,by simulating the accuracy of the integrated navigation positioning of INS/Photogrammetry by multi-rate EKF filter,to verify the feasibility of the aircraft landing/carrier landing.
