Satellite & Propagation
Track amateur satellite passes, predict contact windows, and model HF propagation for DX planning. Know when the bands will be open before you sit down at the rig.
Predict
Live interfaceA real-time satellite tracking and orbit prediction tool with a built-in web server. Track the ISS, AMSAT birds, and any other satellite using current TLE data. Shows azimuth, elevation, Doppler shift, and pass windows. Lightweight enough to run on a Raspberry Pi alongside your station.
sudo apt install predict
VOACAP
The industry-standard HF propagation prediction tool originally developed by the Voice of America. Models ionospheric propagation between any two points on earth for any frequency, time, and solar conditions. Essential for planning DX expeditions, scheduling skeds, and understanding why the bands behave the way they do.
