A space postcard from the "MONITOR-3" satellite for Cosmonautics Day
In celebration of Cosmonautics Day, the small spacecraft "MONITOR-3 (RS58S)" will broadcast images using the SSTV protocol.
Important date
On April 12, 1961, Yuri Gagarin completed the first orbital flight aboard Vostok-1, marking the dawn of the space age. In memory of this event, the "MONITOR-3 (RS58S)" satellite will transmit thematic images available for reception by radio amateurs worldwide.
About the satellite
The "MONITOR-3" (RS58S) spacecraft was launched on June 27, 2023, from the Vostochny Cosmodrome as part of the Space-Pi program. The operator is the Skobeltsyn Institute of Nuclear Physics (SINP MSU). Its primary scientific payload is the DEKOR-2 instrument (developed at SINP MSU), designed to monitor charged particle fluxes in low Earth orbit.
SSTV transmission schedule
· Start: April 10, 2026, ~00:00 UTC
· End: April 13, 2026, ~19:00 UTC
· Mode: Robot 36
· Interval between images: 120 seconds (subject to change)
Downlink frequency:
435.290 MHz — modes: GMSK 2k4/4k8/9k6 USP FEC + SSTV
⚠️ Note: SSTV transmission may be interrupted if necessary (e.g., temperature rise, battery discharge, priority to scientific tasks).
Where to track telemetry and satellite status
· "Ether" network
· "Sonix" network
Radio amateurs and space enthusiasts worldwide are invited to receive the images and celebrate Cosmonautics Day with a unique signal from orbit.Как
