AERPAW helikite spectrum measurements at Packapalooza Festival in Aug 2025

We conducted a spectrum monitoring experiment using a helikite in an urban environment during NC State’s Packapalooza festival in August 2025. The helikite was equipped with a software-defined radio (SDR) and global positioning system (GPS) receivers and flown for approximately 6 hours, starting around noon. The helikite reached an altitude of approximately 160 meters at its peak. The spectrum was continuously swept up to 6 GHz, with each sweep taking about 15 seconds. , , # AERPAW helikite spectrum measurements at Packapalooza Festival in Aug 2025 ## Description of the data and file structure ## Overview This dataset, **“Spectrum monitoring dataset by a helikite in an urban area”**, was collected by **AERPAW**.\ It contains spectrum measurements conducted using a helikite-based platform in an urban environment.\ The dataset follows the **SigMF v1.2** standard for signal metadata formatting.\ MATLAB post-processing scripts are also included.\ Please refer to the **README** file for setup and usage instructions. --- ### Files and variables ## Contents * **SigMF-formatted power spectrum raw dataset**\ Located in the folder `pow_spec/` * **SigMF-formatted GPS logs**\ Located in the folder `GPS_logs/` * **SigMF-formatted spectrum monitoring logs**\ Located in the folder `GPS_logs/` * **SigMF to MATLAB format conversion script** * `sigMF2mat_PW.py` converts SigMF-formatted power spectrum data to MATLAB (`.mat`) files * **SigMF to CSV format conv...,
