Abstract
This paper presents a multi-information integrated landing navigation system for ship landing. It includes satellites, pseudolites, vision and inertial navigation systems. Pseudolites and satellite systems can provide the relative positions between plane and ship, and the vision system can get the relative positions and attitude by identifying targets on the runway. The airborne inertial navigation can provide the aircraft motion information, and the data link can receive the ship motion information. INS is selected as the federated filter reference system, and the satellite, pseudolite, visual and inertial navigation information are fused by the federated filter to Provide navigation information. Through designing simulation experiment by MATLAB. Under the set simulation conditions, the lateral and longitudinal position deviation between the aircraft and the ship is about 0.1m, and the relative vertical position deviation is within 0.3m, which achieve the precision requirement of shipboard landing. The simulation experiment shows that the multi-information integrated navigation method is practicable.
