HADES-SA (SO-127): track the tiny ham-radio satellite live
HADES-SA — call sign SpinnyONE, designated Spain-OSCAR 127 (SO-127) — is one of the smallest amateur-radio satellites in orbit: a 1.5P PocketQube barely bigger than a matchbox, built by the Spanish AMSAT-EA volunteer team. Cosmik shows its live position in 3D, its ground track, and when it passes over your location — free, no login.
Despite its size, HADES-SA is a fully working ham-radio spacecraft. It runs a store-and-forward bulletin board for text messages and CODEC2 digital-voice recordings, and carries a tiny camera that beams down images every few days using the open SSDV protocol — a live demo of open satellite protocols that any operator with a modest UHF antenna can receive.

Can you see HADES-SA (SO-127) with the naked eye?
Not with the naked eye — a 1.5P PocketQube is only about the size of a large matchbox, far too small and faint to spot even on a good pass. The way to "catch" HADES-SA is by radio: point a modest UHF antenna up during a pass and decode its 436.875 MHz FSK downlink to pull down live telemetry, CODEC2 voice and SSDV images. Cosmik computes those pass windows for your exact location so you know when to listen.
Frequently asked questions
What is HADES-SA?
HADES-SA (SpinnyONE) is an amateur-radio PocketQube built by AMSAT-EA and designated Spain-OSCAR 127 (SO-127). Launched in March 2026, it carries a message bulletin board, CODEC2 digital voice and an SSDV camera — all on open protocols anyone with a ham licence can use.
What frequency does HADES-SA transmit on?
Its coordinated downlink is 436.875 MHz in the 70 cm amateur band, sending FSK data at 200–1200 bps — telemetry, CODEC2 voice recordings and SSDV images. Hobbyists decode it with a cheap RTL-SDR and a small UHF antenna; Cosmik tells you when it's overhead so you know when to record.
Can you see HADES-SA with the naked eye?
No — at just 1.5 PocketQube units (roughly 5 × 5 × 7.5 cm) it's one of the smallest satellites in orbit and far too faint to see. You track it by radio, not by eye. In Cosmik's 3D view you can still watch its ground track sweep the globe.
