为了给无人机飞行提供精确的导航信息,建立精度因子的Matlab/Simulink仿真模型。基于GPS全球定位系统,以无人机经过复杂山地为例,建立无人机导航精度因子数学模型,并利用Matlab/Simulink仿真工具对模型进行仿真分析。仿真结果表明:建立的精度因子模型得到的精度值较高,能够满足无人机在复杂山地下的导航需求和作战要求。
In order to provide accurate navigation information for UAV flight, a Matlab / Simulink simulation model of precision factor is established. Based on the GPS global positioning system, taking the UAV traveling through complex mountainous area as an example, the mathematic model of UAV navigation precision factor is established and the model is simulated by Matlab / Simulink simulation tool. The simulation results show that the established accuracy factor model has a high accuracy value, which can meet the navigation requirements and operational requirements of the UAV under complex mountainous conditions.
