SpaceAPRS: Amateur Radio Heard from Orbit

spaceaprs.com Observed source

Editorial interest 78/100 Selection signal · not a rating of the site

A live map of amateur-radio stations whose APRS packets are relayed through the International Space Station.

Landing page captured for the 2026-09-15 issue.

Field notes

The ISS view pairs orbital tracking with amateur-radio reception, using time windows of live, three hours, 24 hours, and seven days to organize packet activity. It identifies the 437.825 MHz channel and attributes the station operation to ARISS; the captured state showed no packets in the selected window and asked visitors to wait for the next one. Related navigation exposes stations, packets, and passes rather than presenting only a single visualization.
