About this tool
Reading a pass
Rise and set are when the satellite crosses your minimum elevation; peak is its highest point. Passes above 30° are the easiest to receive, because the signal travels through less atmosphere and fewer obstacles.
Can I see it?
"Visible to the eye" means the satellite is in sunlight while your sky is dark, the classic ISS sighting right after dusk or before dawn. "Sunlit (daytime)" passes can still be received by radio.
Doppler shift
Satellites move fast, so their signal arrives higher in frequency as they approach and lower as they leave. For narrow FM voice, tune a few kHz high at the start of a pass and step down as it passes.
