About MARINA

MARINA is a 1U CubeSat from Slovakia, the second satellite of the private "Satellites with Meaning" initiative after VERONIKA. It was built by the company Spacemanic and is operated by the Faculty of Aeronautics of the Technical University of Košice. It was launched on 7 July 2026 on SpaceX's Transporter-17 rideshare from Vandenberg. Its science payload, a MiniPIX Space radiation detector, measures radiation and space weather in orbit, and its radio was designed to give radio amateurs a digital transponder and SSDV pictures, planned for five years of operation according to its frequency application.

Its main service is a digital transponder (digipeater) for 9600 baud GFSK AX.25 packets with G3RUH scrambling, the same mode the team used on the earlier Slovak satellites GRBAlpha and VERONIKA. AMSAT's digipeater list gives downlinks on 145.925 MHz and 436.680 MHz and the path alias OM9MAR. The second service is SSDV: an onboard camera takes pictures of the Earth that come down as packets, and you can rebuild an image even if some packets are lost.

According to the team's plan, about 40 percent of the time is given to the transponder, 40 percent to SSDV images and the rest to telemetry and commanding, so what you hear depends on the mode of the day. A 9600 baud packet station with a directional antenna gives the best results.
