ARISS station status ↗Satellites
Amateur-radio satellites
ISS, SO-50, AO-91, and RS-44 reference notes, with current status links to their operators and AMSAT.
THE SHORTLIST
A few familiar voices.
Orbit tracking is always separate
from the radio’s operating status.
SO-50
SaudiSat-1C, an amateur FM repeater satellite. Check AMSAT’s operating notes and recent reception reports before a pass.
FM satellite reference ↗AO-91
Fox-1B / RadFxSat. AMSAT’s battery guidance calls for sunlight-only access; seeing it on the map does not mean the repeater is available.
Check operating restrictions ↗RS-44
DOSAAF-85 carries a linear amateur-radio transponder. Follow the frequency reference and current reports for operating details.
