AERPAW helikite spectrum monitoring at Packapalooza festival in Aug 2022

In this dataset, we conducted a spectrum monitoring experiment in an urban environment. The helikite flies up to an altitude of 400 feet throughout the day from noon to 9 p.m. during NC State’s Packapalooza festival in August, 2022. The spectrum is swept up to 6 GHz. Every sweep takes around 1 minute, while after every 4 measurements, the 5th measurement takes close to 5 minutes due to another data collection activity running in parallel. The photo of a flying Helikite at the experiment site is shown in the dataset image. The helikite goes up and stays at an altitude of around 400 feet and goes down around an altitude of around 70 feet four times during the whole measurement period., , , # AERPAW Helikite Spectrum Measurements at Packapalooza in Aug 2022

Spectrum monitoring dataset by a helikite in an urban area, which is measured by AERPAW.
The dataset is formatted by SigMF. Please find instructions in the readme.
MATLAB post-processing code for the dataset is attached as well.

## Description of the data and file structure

### Contents
1. SigMF formatted power spectrum raw dataset in the folder named pow\_spec
2. SigMF formatted GPS logs in the folder named GPS\_logs

2. Run 'sigMF2csv\_GPS\.py' to get a csv file for GPS logs\. The output files are located at '\.\\GPS\_log...

本数据集针对城市环境开展了频谱监测实验。2022年8月北卡州立大学（NC State）Packapalooza活动期间，系留氦气飞艇（helikite）于当日正午至晚间9点持续升空作业，最大飞行高度达400英尺。本次实验扫频范围上限为6 GHz，单次扫频耗时约1分钟；但每完成4次测量后，第5次测量将因并行开展的另一项数据采集任务，耗时增至近5分钟。实验现场飞行中的helikite照片已收录于数据集配套图像文件中。在整个测量周期内，helikite共计4次攀升至约400英尺高度悬停，随后下降至约70英尺高度。
