The UK is betting £600 million that laser-powered satellites are the future
Three Scottish-built satellites have been blasted into orbit aboard a SpaceX Falcon 9 as part of the Transporter-16 rideshare mission, delivering a tangible milestone in the UK’s push to dominate next-generation satellite communications.
The satellites, developed by Glasgow-based firms Spire Global UK and AAC Clyde Space, were funded through the UK Space Agency via the European Space Agency’s Pioneer Programme.
One of them carries a pioneering optical inter-satellite link (ISL) payload designed to demonstrate high-speed laser crosslinks on a compact 6U CubeSat platform.
Why lasers could reshape satellite networks
Traditional satellite constellations rely on radio-frequency signals, which face limitations in speed, latency, and bandwidth as data demands explode.
Laser-based optical links use focused beams of infrared light to transmit data between satellites at much higher rates – potentially slashing latency for critical applications like real-time aviation tracking, maritime safety, weather forecasting, and space-weather monitoring.
Once proven, the technology promises near-real-time global data delivery across large nanosatellite constellations, bypassing bottlenecks in ground-to-space and inter-satellite communications.
“This Transporter-16 launch marks an important step forward for the UK’s ambitions in next-generation satellite communications,” said Henny Sands, Head of Telecommunications at the UK Space Agency.
“By supporting both breakthrough optical technologies and high-volume production methods, we are enabling British companies to lead in the markets that will define the future of global connectivity.”
A £600 million bet
The UK Space Agency plans to invest more than £600 million in satellite communications research and development over the coming years.
This includes the Connectivity in Low Earth Orbit (C-LEO) programme, which recently opened a new £30 million funding call for UK companies to develop components and technologies for satellite constellations, with another round expected later in 2026.
Satellite communications have been designated a strategic priority for both civil and defence applications – from delivering broadband to remote UK communities to ensuring secure, resilient connectivity for military operations.
The two other satellites on the mission, built by AAC Clyde Space, form the first in-orbit demonstration of the UK’s emerging high-volume, low-cost satellite production capability.
They will contribute to the company’s VIREON constellation, aimed at providing space-enabled insights for agriculture, forestry, and environmental management.
Glasgow’s growing role in space
The missions show Glasgow’s emergence as Europe’s leading hub for small satellite manufacturing. Development involved collaboration with partners including Bright Ascension Ltd., the University of Strathclyde, the Satellite Applications Catapult, Alden Legal, and D-Orbit UK.
By backing optical ISL technologies alongside advanced manufacturing and operations platforms, the UK aims to build a robust domestic supply chain and create high-skilled jobs.
The government sees laser communications as a key differentiator in an increasingly crowded and competitive global market projected to be worth tens of billions annually. Success here could position British firms to supply components and entire systems to major constellation operators worldwide.
