Research And Visual Simulation On Tan/Sins/GPS Integrated Navigation System

To satisfy the higher requirement of modern aircraft to the navigation systems, this dissertation principally lucubrate the TAN/INS/GPS integrated navigation system. In this paper, some representative views are presented and the key techniques of the multi-sensor navigation system are applied, such as the data fusion and the Federated Filter, to the above system. When studying in theory, visual simulation of the TAN/INS/GPS system has been done using advanced programming languages. The author attempts to present the fuzzy adaptive Kalman Filtering technique and apply it to the SINS/GPS system.The whole paper has two parts, that is, theoretical study and visual simulation. The contents and main contributions are summarized as follows:(1) Respectively studies on the SINS/GPS and TAN in the way of principle, mathematical model and performance; In depth researches the Terrain-Aided navigation technique based on elevation matching; Studies the application of Federated Filter in the TAN/INS/GPS system.(2) Visual simulation of the TAN/INS/GPS system has been done using advanced programming languages and the software has been designed out.(3) Presents an innovative technique of fuzzy adaptive Kalman Filtering and testifies it effective by simulation.I hope new and effective methods to be given here and hope this paper to contribute to the new visual intelligent fault-tolerant navigation system.
