摘要
在无人机降落过程中,高精度的助降引导系统不可或缺。目前,在复杂的地形、天气条件和存在电磁干扰等不利环境下,无人机助降引导系统存在降落定位误差较大的问题。为实现无人机的精准定位降落,研发了基于紫外信标的无人机高精度助降引导系统,测试结果表明,紫外信标助降引导系统能够满足高精度定位需求。系统定位精度高,可适用于雾霾天气、复杂地形、电磁干扰等特殊环境,为无人机降落过程提供了一种可靠精准的引导方式。
In the process of landing of UAV,high-precision auxiliary landing navigation system is indispensable.At present,under the unfavorable environments of complex terrain,weather conditions and electromagnetic interference,the usual auxiliary landing navigation system has a problem of large landing positioning error.To this end,a high-precision auxiliary landing navigation system based on ultraviolet beacon is developed.The test results show that the auxiliary landing navigation system can meet the high-precision positioning requirements.The system has high positioning accuracy and can be applied to special environments such as haze weather,complex terrain and electromagnetic interference.It provides a reliable and accurate navigation method for the landing process of UAV.
