Decoder for the CubeSail satellite's beacon

CubeSail Beacon Decoder

CubeSail is a technology demonstration by CU Aerospace which shows the viability of solar sail propulsion for deep space missions. It was built and is operated by students at the University of Illinois at Urbana-Champaign through the Satellite Development, or SatDev student organization.

Interested in decoding beacons for us? Here's what you need to know:

Frequency: 437305kHz

Modulation: GFSK (GR3UH scrambling)

Bandwidth: 15kHz

Callsign: WI2XVF

Link Layer: AX.25/HDLC

Baud Rate: 9600

TLE (accurate until 2018/12/17):

cubesail_temp
1 99999U 18350.31100694 .00048519 00000-0 21968-2 0 00004

The decoder, decoder.py can be run using Python 3. It will guide you through the data entry process.

Usage

1. Download Python for your machine if you don't already have it. Linux users, get it through your distribution's repositories. If you plan to do more than this one project with Python, I'd recommend installing Anaconda

2. Download git for your machine, and get the script using:

git clone https://github.com/ijustlovemath/cubesail-decoder.git

Alternatively, visit the GitHub link and download the script in a zip file.

3. Run the decoder in Python

python3 decoder.py
