| Abstract: | In this paper,the basic principles of the actual navigation system are discussed,the working principles of the gyro and accelerometer and the output of measurement parameters are also analyzed.Considering current development of aviation simulation technology and practical request of the prototyping of full flight simulator,radio navigation models with the method of region navigation as well as strap-down inertial navigation models are made on MATLAB/SIMULINK platform intended for the simulation of outer characteristics of the navigation system.Through construction of a distributed flight simulation system based on RT-LAB platform,the outer characteristics of the navigation system are achieved with hardware-in-the-loop simulation.As one node in the whole simulation system,the navigation system plays a key role in communicating with other nodes.So that the system of Auto-navigation come true. |
