Estonian Golbriak Space raises €4M for satellite laser comms

Estonian startup Golbriak Space has raised €4 million to scale production of laser terminals for satellite constellations. The fresh capital will be used to accelerate industrialisation of its optical communications technology and expand manufacturing capacity.

The round, reported by tech.eu, follows a period of activity in the European space sector. Earlier coverage included Cosmos and Open Cosmos securing $346 million each in September, alongside other funding announcements like Foundational’s £8.2 million pre-seed round and Charter Space’s $5 million insurtech raise.

Optical communications technology is often positioned as a potential successor to traditional radio-frequency systems, with proponents citing advantages like higher data rates and lower latency. Whether operators will adopt it widely—or opt for hybrid approaches—remains an open question.

Golbriak’s funding, while smaller than some recent space deals, suggests continued investor attention on satellite infrastructure. How quickly the industry moves toward laser-based solutions could become clearer as production scales.
