Gpredict is a real-time satellite tracking and orbit prediction desktop application using SGP4/SDP4 propagation with NORAD TLE data. It displays satellite positions on maps, lists, and polar plots, predicts passes, and controls radios and antenna rotators via Hamlib.

Use cases

• track satellites in real time from my ground station
• predict upcoming satellite passes over my location
• control my antenna rotator to follow satellites automatically
• doppler-tune my radio for satellite contacts
• visualize satellite positions on a map and polar plot
• track many satellites with multiple ground stations

When to choose

• you are a ham radio operator or satellite enthusiast needing real-time tracking and pass prediction
• you want automated antenna rotator and radio Doppler control via Hamlib
• you need flexible visualization with maps, tables, and radar views grouped into modules

When to avoid

• you need a headless or programmatic satellite tracking library rather than a GUI app
• you need interplanetary or deep-space orbit propagation (planned but not implemented)
• you require a mobile or web-based tracking solution
