Reaktor Space Lab and VTT investigate a new frequency band for telecommunications satellites

1 min read

Reaktor Space Lab and VTT Technical Research Centre of Finland are participating in an European Space Agency project, which involves investigating a new frequency band for next-generation telecommunication satellites. A nanosatellite to be constructed as part of the project will feature a Finnish platform and radio transmitter. As the number of satellites and the speed required for data communications increase, transition to higher frequencies will become a necessity in the near future. 

Funded by the ESA as part of its ARTES programme, this activity will demonstrate the use of the 75GHz frequency band for future telecommunications satellites. The test flight will be carried out using a Finnish-made CubeSat satellite, weighing less than 5kg, and is scheduled to launch next year.

The satellite's mission is to send, for the first time in history, such a high-frequency signal from space to Earth. The transmission of the signal through the atmospheric layers must be substantiated before telecommunications satellites that utilise the new frequency band can be designed with the desired features.

The satellite to be built for the project is based on Reaktor Space Lab’s ‘Hello World’ satellite platform, which will be launched on its first mission this summer.

The satellite, named W-Cube, will feature an integrated dual-frequency beacon transmitter developed by VTT. The signal it broadcasts will be observed at the prime contractor JOANNEUM RESEARCH’s measurement station in Graz, Austria.
