The purpose of this study is to establish a UAV platform that receives wireless transmission control instructions, and to achieve a precise positioning system by carrying a flight control system, a wireless signal receiving sensor, an UWB base station, and a base station delivery device. The self-localization algorithm, which utilizes a distributed multi-UWB base station network and information fusion techniques, is employed to achieve autonomous positioning of UAVs under simulated conditions. This approach circumvents the dependency on satellite navigation, mitigating the impact of satellite signal loss on the UAV's positioning capabilities. Through inertial navigation technology and UWB base station delivery, a global coordinate system is established to provide accurate position information for the UAV. The project also includes simulation and physical verification to optimize and achieve precise positioning functions.
