European Space Agency (THIS) and Lithuanian space startup Astrolight are collaborating on a ground-breaking project: construction of the first optical ground station (OGS) to Kangerlussuaq, Greenland. The initiative is aimed at improving terrestrial communication and strengthening protection against signal interference. Expected, what, using laser technology, the station will provide superior space-to-ground communications compared to radio frequency systems. It will also play a critical role in improving disaster detection, rescue efforts and support of critical infrastructure.
Astrolight, founded in 2019 year, specializes in laser communication systems for various fields, including space, land, air and sea. The company expects to complete the construction of the new facility by the end 2026 year, which will allow the OGS to serve as a vital link between satellites, revolving around the Earth's polar region, and terrestrial data networks. The station will primarily serve such customers in the telecommunications and Earth observation sectors, like space agencies, government agencies and commercial satellite operators, focused on the collection of optical, hyperspectral, radar and infrared data.
According to forecasts, over the next decade, the volume of data, transmitted from space to Earth, will increase in 14 times (to over 500 billions of gigabytes), therefore, the existing radio frequency stations will no longer be sufficient to transmit this amount of information. That is why the transition to the optical spectrum will be needed, similar to the transition to fiber internet on Earth. Astrolight is working to address this as a key hurdle, as traditional radio frequency communications are not keeping pace, laser links provide much higher bandwidth, reduced cost per GB and increased information security. The Lithuanian company also announced plans to integrate back-up distribution channels, using LEO and geostationary orbit satellite repeaters, which will enhance the overall reliability of space-to-ground data links in the Arctic. At the same time, Astrolight aims to increase production and sales of its Polaris marine laser communication terminals and Atlas space terminals in 2026 year, and will also develop additional opportunities for space-to-space optical communication.
