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 increase the popularity of BFRA among young people henceforth to enrich the Radio Amateur community in Bulgaria.
The satellite will have CW beacon which will transmit its own call sign using Morse code and telemetry beacon using AX.25 in datagram-mode. The radio amateurs will be able to listen to the satellite beacon and to receive 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 connection which will serve as QSL card.
Power generation and communication in one single module
Engineered for space research and applications
Cutting-edge features and high-reliability ensure your power supply in space
On this webpage all the information and instructions required to connect with the satellite will be published as well as online database where all users will be able to upload the data they receive directly from the satellite. A competition will be held and a log file with all the successful communications will be published. The call sign with the most uploaded telemetry data will be announced by the satellite through its beacon.
BFRA will guide the students to experience their first space mission by connecting with the CubeSat once in orbit. They will learn satellite communication by practicing.
How to connect with the satellite
Information and instructions required to connect with the satellite and competition page with the rank of call signs with the most uploaded telemetry data will be published on this page.

EnduroSat One will be embarked on the cargo resupply mission SpaceX CRS-14 to the International Space Station manifested to be launched on February 2018 from Cape Canaveral SLC-40 launch base in Florida, USA.
EnduroSat One will be launched with the SpaceX Falcon 9 rocket / CRS-14 mission
EnduroSat One will be delivered to the ISS
A crew member of the ISS will transfer EnduroSat One to the deployment system.
EnduroSat One will be deployed from the ISS and placed into LEO orbit.
EnduroSat One will be orbiting at approx. 400km.
EnduroSat’s Ground Station will operate the satellite.
Radio amateurs will receive instructions how to connect with EnduroSat One.
During the mission, Space Challenges team will record educational video materials and will publish them online in English and Bulgarian, demonstrating satellite communication techniques and increasing the popularity of the Radio amateur society in the region.
This will be made possible by Spaceport online educational platform. Spaceport is the biggest online platform for space education in Europe https://spaceport.academy and the developed materials during EnduroSat One mission will guarantee maximum project exposure to young people.
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).
What does the satellite include?
The 1U EnduroSat CubeSat is a multipurpose platform engineered for space research and application. The EPS+ and the solar panels will ensure power supply during the mission. Two UHF Transceiver type II and the UHF deployable antenna will provide an high-reliable communication system for TT&C and data. Processing capabilities are provided by the low power consumption and high performance Onboard computer. A network of sensors and actuators will enable spacecraft control.
