A British space surveillance company which has won a string of government contracts will this week announce a £5.4m fundraising to expand its global network of advanced telescopes.

Sky News understands that Spaceflux, which was founded three years ago, has secured the injection of capital in a round led by the UK Innovation & Science Seed Fund (UKI2S), which is managed by Future Planet Capital, as well as Foresight Group and Blackfinch Ventures.

Seraphim Space, the listed specialist investor in space-related companies, is also contributing funding.

Spaceflux uses artificial intelligence and optical sensors to track satellites and debris across all orbits, with its daylight tracking capability meaning it can expand the observation window beyond night-time operations.

Its provision of space situational awareness technologies is in growing demand amid warnings that a week-long disruption to satellite navigation could incur a £7.6bn hit to the UK economy.

In a statement to Sky News, Marco Rocchetto, CEO and co-founder of Spaceflux, said: “As space becomes increasingly essential to our economy, environment and daily lives, it is also becoming more congested and contested.

“This investment strengthens our ability to protect satellite technology that delivers crucial insights to Earth around the clock, reducing collision risks, and supporting a safer, more sustainable space environment for future generations”.

The valuation at which the funding was being committed was unclear on Thursday.

Spaceflux, which serves government and commercial customers, has been the exclusive provider of geostationary satellite tracking for the Ministry of Defence and UK Space Agency since 2023.
