 # Q-Drone UWB Benchmark Dataset
 ## Overview
 We present a unique UWB benchmark dataset, called Q-Drone UWB benchmark. Q-Drone system, a UAV with UWB network built at York University, was used for acquiring this benchmark over five different sites, which include an indoor, open sports field, near to a building with glasses, semi-open tunnel and underneath bridge. The benchmark data were acquired by flying for a total of 1 h 50 min 28 sec flight time and about 4.3 km traveling distances with different maneuvering patterns and spatial configuration between UAV and UWB anchors as shown in the following table.
