Link to Dataset

  • Dataset Link: The dataset includes UAV trajectory data collected at three altitudes (40 m, 70 m, and 100 m), with the 40 m altitude sampled at rates of 5 MHz, 10 MHz, and 20 MHz. Data was recorded in 20 ms intervals every 100 ms using USRP B210 devices at five fixed nodes (LW1-LW5), with IQ samples for two channels captured in each SigMF file, reflecting the dual-channel configuration of the USRPs. The SigMF format dataset including format conversion codes can be accessed here [Dryad].

Description

This dataset contains wireless communication signal data collected from an unmanned aerial vehicle (UAV) at different altitudes (40 m, 70 m, and 100 m). For the 40 m altitude, data was collected at varying sampling rates (5 MHz, 10 MHz, and 20 MHz), corresponding to bandwidths of 1.25 MHz, 2.5 MHz, and 5 MHz, respectively. The IQ recordings were made using USRP B210 devices at five fixed nodes (LW1-LW5). The dataset includes IQ samples, GPS coordinates, and received signal strength (RSS) values stored in SigMF format files. A Python script (example.py) is provided for data processing and visualization.
