How laser links and high-volume manufacturing are transforming satellite communications
In short: From massive NASA relay systems to compact Glasgow-made satellites, the way we communicate in orbit is shifting. New missions are testing high-speed laser links and mass-production techniques to enable near-real-time data delivery for everything from maritime services to environmental monitoring.
The landscape of orbital communications is bifurcating into two distinct technological paths. On one hand, established systems like NASA's Tracking and Data Relay Satellite System (TDRS) rely on large-scale infrastructure. For example, the Atlas V rocket launched the TDRS-L satellite to an orbit 22,300 miles above Earth to maintain vital links between ground stations and spacecraft like the Hubble Space Telescope and the International Space Station.
On the other hand, a new generation of smaller, more agile satellites is emerging from hubs like Glasgow, which is positioning itself as Europe's leading city for small satellite manufacturing. Recent SpaceX Transporter-16 missions have carried satellites from companies like Spire Global and AAC Clyde Space, representing a shift toward high-volume, low-cost production. These missions are testing the limits of what compact platforms can achieve in orbit.
A critical frontier in this evolution is the use of optical inter-satellite links (ISL). Spire Global UK is currently testing an innovative payload on a compact 6U platform to demonstrate high-speed laser crosslinks. Once proven, this tech might greatly lower latency for maritime, aviation, weather, and space-weather sectors through near-real-time data transmission via nanosatellite constellations.
This industrial shift is backed by significant investment. The UK Space Agency has identified satellite communications as a priority for both civil and defence applications, including remote broadband and secure military connectivity. To support this, the agency intends to invest more than £600 million in satellite communications research and development over the coming years. This effort is bolstered by the European Space Agency’s Pioneer Programme, which operates under the Advanced Research in Telecommunications Systems (ARTES) framework.
