We present an Ultra-Wide Band (UWB)-based multiple Unmanned Aerial Vehicle (UAV) control system architecture to localize and track a ground vehicle. A team of UAVs self-localizes its position measures distance vehicle using the mounted UWB module. The server utilizes estimated UAV measurements collected from radio communication between (i.e., mobile anchor) in order accurately. then sends next setpoint each enables form polygon-shaped formation with located at center. demonstrate our...

Among the various Ultra-wideband (UWB) ranging methods, absence of uplink communication or centralized computation makes downlink time-difference-of-arrival (DL-TDOA) localization most suitable for large-scale industrial deployments. However, temporary permanent obstacles in deployment region often lead to non-line-of-sight (NLOS) channel path and signal outage effects, which result errors. Prior research has addressed this problem by increasing frequency, leads a heavy increase user device...
