Slovakia is gearing up to launch its first satellite to orbit with the aim of demonstrating the country’s ability to carry out scientific experiments in space. The pocket-sized one-unit CubeSat, named skCUBE, is currently slated for liftoff in June atop SpaceX’s Falcon 9 rocket from the Vandenberg Air Force Base in California. The central European state is one of the last countries on the continent to have its own satellite.

Weighing about 2.2 lbs. (1 kg), skCUBE is a 4-inch (10-centimeter) cube that will carry an onboard computer, a communications system, and a small camera to conduct experiments when orbiting Earth. The main goal of this project is to demonstrate that Slovakia is capable of doing highly sophisticated space research.

“We see the development of skCUBE as a first spark of light in showing the world that Slovakia belongs to countries with a potential in space science and industry. We want to show that Slovakia has excellent universities, science institutions, and companies which innovate and make our country a good name around the world and going to prove it through our first satellite Made in Slovakia,” Lucia Labajova, Marketing Manager of the Slovak Organization for Space Activities (SOSA), told

SOSA, founded in 2009, is a non-governmental entity developing the skCUBE project. The organization was established to popularize space research and to increase general awareness about the importance of space industry. It is also actively promoting the entry of Slovakia to the European Space Agency (ESA).

SkCUBE is also backed by the government and could serve as an example of cooperation between universities, students, companies, and other supporters. The Ministry of Education, Science, Research and Sport, and the Ministry of Transport, Construction and Regional Development dedicated to the satellite about $102,000 (€90,000) in total. Many Slovak companies support the project with their know-how, qualified employees, and also financially.

“SkCUBE is developed and built by Slovak engineers and scientists as a national project demonstrating an excellent cooperation of our state, universities, students, companies, and other supporters, such as astronomy fans,” Labajova said.

The tiny spacecraft is fitted with an electricity supply system, a sensory system, and an orientation control instrument. The camera on board the satellite will be capable of taking images with a resolution of 750 × 480 pixels. Its angle of view is 60 degrees and it contains infrared and neutral density filters.

SkCUBE will focus on ham radio experiments that will include connection of two amateur radio operators via the satellite, sending of basic telemetry data via Morse code for easy listening, and high-speed data and image transmission via the 2.4 GHz band.

Labajova noted that radio amateurs from all over the world will have the possibility to receive a picture, which will be marked with the skCUBE name, the call sign OM9SAT, and a timestamp. It will only contain information in accordance with amateur radio regulations. Transport Protocol and possibilities for the signal reception will be published in advance on the project’s website.

The ham radio research will also include a VLF receiver with a frame magnetic loop antenna – which enables the reception of radio signals in the range 3 to 30 kHz – spectral analysis, and data transmission to the ground. The data will be public and can be used to further scientific analysis.

Other technological experiments will see studies such as attitude control of the satellite in space using magnetic coil actuators or checking radiation resistance of critical technology components (DC-DC converters, current meters, switching transistor, RAM, FRAM, FLASH memory).

Jakub Kapus, the chairman of SOSA, is leading the skCUBE effort. The project team consists of scientists from the Zilina University, the Slovak technical university in Bratislava, and the Faculty of Aeronautics at the Technical University Kosice.

“In the beginning, when SOSA was founded, we had a goal to achieve something almost unimaginable for such a small group of people. We were connected by our passion for space and new technologies and wanted to push the Slovak space science and technology another step forward to later eventually become a full member of ESA,” Labajova said.

“History is formed by brave and stunning acts. Today we are happy to present SOSA as a group of capable young scientists, engineers, and people who want to push the boundaries forward towards a new frontier,” she added.

Slovakia signed the European Cooperating State Agreement with ESA in February 2015. The nation has been actively involved in space physics research and in astronautics, having two cosmonauts, the Czechoslovak Vladimír Remek (flew in space in 1978), and the Slovak citizen Ivan Bella, who spent nine days on board the Mir space station in 1999.

Although Czechoslovakia has already sent its first satellite into space, Magion 1, in October 1978, Slovakia, as an independent country, hasn’t yet put its homegrown spacecraft in orbit around Earth.

The launch of skCUBE was initially scheduled to be launched on April 16, but that was postponed and is now planned for June. However, the exact date is yet to be decided. Currently, SpaceX aims to conduct two orbital missions in June.

Labajova said that at this moment everything is on track for the June liftoff and the team can focus on the arrangements for the launch. However, in the beginning, it was a long and difficult bureaucratic process as the skCUBE will be the first Slovak object in space.
