NOAA APT Satellite Signal Decoder

A tool to decode NOAA APT satellite signals from .wav recordings into grayscale satellite images.

Why This Project?

I created this to learn Haskell through a real-world problem: decoding NOAA's Automatic Picture Transmission signals.

Overview

• Input: Accepts .wav files of APT satellite transmissions.
• Processing: Decodes signals into pixel data using Haskell.
• Output: Generates grayscale PNG images of satellite passes.

Installation

With Stack

First ensure you have Stack.

git clone https://github.com/zietzm/satellite.git
cd satellite
stack install
satellite-exe --help

With Nix

If you prefer, use Nix.

git clone https://github.com/zietzm/satellite.git
cd satellite
nix develop
stack install
satellite-exe --help

Usage

satellite-exe input-file.wav output-file.png

• input-file.wav: Recorded NOAA APT signal.
• output-file.png: Output satellite image.
