£8.2m · Pre-Seed · Space · London, UK
London-based Foundational has emerged from stealth with £8.2m in pre-seed financing to build a commercial satellite laser-ranging network. The financing was led by Inflection, with participation from BACKED, Adjacent, Type One Ventures and Final Frontier. According to Payload Space, the company will use the capital to deploy ground stations, manufacture hardware in-house, expand production of its satellite-mounted reflectors and develop its orbital-data platform.
Turning precision ranging into a network service
Satellite laser ranging measures distance by firing short laser pulses from the ground and timing their return from a reflector on a spacecraft. The technique is well established in scientific geodesy: NASA describes modern systems as capable of millimetre-level measurements. Foundational’s commercial proposition is to package that precision into a service for satellite operators rather than require each customer to build and staff specialist infrastructure.
The system has three parts. Passive retroreflectors ride on customer satellites and continue returning laser pulses even after a spacecraft loses power. Automated ground stations, each roughly the footprint of two pickup trucks, collect the measurements. Foundational’s Origin software platform then turns those observations into orbital data customers can use for navigation, servicing and communications operations. The company says its stations can be materially cheaper than legacy installations, while the automation is intended to make a geographically distributed network practical.
That network model matters because a single precise observation is less useful than dependable coverage. More stations create additional viewing opportunities and redundancy; more reflectors make the service addressable to a larger fleet. Foundational is therefore building both sides of the system at once. The hardware can improve an operator’s orbit knowledge, while the recurring data layer is where the company expects to form an ongoing commercial relationship.
The network build is the proof point
Foundational says 16 of its reflectors are already in orbit and around 60 more are awaiting launch. The first four to five ground stations are under construction across four continents, with service expected to begin in early 2027 from the first three or four sites. Its longer-term plan is a network of 10 to 20 stations and, beyond reflector-equipped spacecraft, capabilities for tracking debris and other objects.
Execution now depends on turning those deployments into consistent measurement coverage. The reflectors are passive and relatively simple, but the value of the service will be tested by station uptime, geographic density and the speed with which observations become usable customer data. Foundational’s founders bring relevant continuity: chief executive Hira Virdee founded satellite-ranging company Lumi Space in 2018, and teamed with chief technology officer Dave Gooding in 2025 to establish Foundational, with Lumi continuing as a subsidiary.
