无线日盲紫外光测距定位方法
Ranging and positioning method using wireless solar blind ultraviolet
摘要
Abstract
In order to solve the problem of positioning in UAV flight and landing guidance scene ,this paper presented a ranging and positioning method based on wireless ultraviolet lights .The method analyzed communication models of wireless ultraviolet Line of Sight (LOS ) and Non-Line-of-Sight (NLOS) ,thus deriving the distance algorithm for LOS and NLOS communications .The location coordinates of unknown nodes were solved by the four node localization algorithm .Using a 255 nm UV LED as the light source ,a PM T as the receiving device and a 10 kHz square wave signal as the ranging signal , ranging experiments under different weather conditions were performed . The experimental results indicate that the ranging error is less than 5 m in LOS communication with the ranging distance of 0~100 m .In NLOS communication ,the effective ranging distance is reduced to 0~70 m due to the influence of multipath scattering .When the transmitting elevation and receiving elevation is less than 10° ,the ranging error is less than 5 m ,otherwise the effective distance decreased significantly with the increase of transmitting and receiving elevations .In general ,the algorithm can provide navigation data for unmanned aerial vehicles with a high accuracy when the GPS cannot work normally ,thus can meet the requirements of autonomous landing and flight guidance .关键词
