Cardputer Adv ISS Tracker

I was looking for a unique project for my Cardputer Adv, and as a ham radio operator I wanted a dedicated tool to track the ISS (and soon maybe even satellites) without needing my phone. So, I wrote this ISS Tracker.

It calculates the live ISS position and future passes in real-time.

Features:

- Live Telemetry: Shows Azimuth/Elevation and Lat/Lon in real-time.

- Radar Skyplot: A visual polar plot showing the satellite's path across the sky relative to your position.

- Pass Prediction: Calculates the next visible pass (AOS/LOS) up to 24 hours in advance.

- Elevation Filter: You can set a minimum elevation (e.g., 10 deg) so it ignores low passes.

- Offline Capable: Once it grabs the TLE data via Wi-Fi, it works completely offline.

- GPS support using the LoRa/GPS cap for the Cardputer Adv.
