EnduroSat One

EnduroSat One [Space Challenges Program]

EnduroSat One is the Bulgaria's first 1U CubeSat mission, developed by Space Challenges program and EnduroSat collaborating with the Bulgarian Federation of Radio Amateurs (BFRA) for the first Bulgarian Amateur Radio CubeSat mission.

The project will include launching of 1U CubeSat from ISS (International Space Station) with goals to foster Amateur Radio’s participation in space research and communication in Bulgaria, to teach the participants in Space Challenges Program and hundreds of students from diverse Bulgarian universities (Sofia University, Technical University - Sofia, Tech university - Plovdiv and others) in practical satellite communication and to promote amateur radio hobby to young people henceforth to enrich the Radio Amateur community in Bulgaria.

The satellite will have two beacons: a CW (A1A) beacon which will transmit its own call sign and some TLM data using Morse code and a telemetry beacon using AX.25 in datagram-mode. Radio amateurs all around the globe will be able to listen to the satellite beacons, to receive and decode telemetry data from the satellite on a regular basis. Every radio amateur will be able to connect to the satellite and receive more detailed telemetry information and get a confirmation from the satellite for every established contact which will serve as QSL card.

Since, this is the first ever Bulgarian radio amateur CubeSat mission, it will undoubtedly create good practices in correct registration and launch preparation processes for future educational and radio-amateur CubeSat programs on local (Bulgarian) level. Those good practices will be shared also on the educational platform of Space Challenges and provided to interested students and radio-amateurs, with permission from the given organizations (including IARU).

EnduroSat One was embarked on the cargo resupply mission Cygnus CRS-9 to the International Space Station launched on 21 May 2018 from Wallops Island. It was deployed on 13 July 2018 via the JEM airlock.
