Toronto-based Kepler Communications has moved its next-generation optical data relay network into commercial service, giving customers faster access to data generated and processed in space.
The milestone follows the completion of commissioning for the first tranche of Kepler’s constellation, launched in January. The company says the network is now supporting commercial and government customers worldwide as the first commercially available space data relay service.
Kepler’s infrastructure combines optical links between satellites with onboard computing, storage, and an internet protocol-based architecture. This allows mission data to be transmitted, processed, and distributed across the network before reaching Earth, reducing delays associated with waiting for a satellite to pass over a ground station.
The approach effectively extends elements of cloud and edge computing into orbit. Kepler says customers can use the network to support Earth observation, space-domain awareness, intelligence, surveillance, reconnaissance, defence, and other applications requiring timely access to information.
The first tranche consists of 10 satellites, each weighing approximately 300 kilograms. Every satellite carries high-capacity optical terminals, multi-GPU computing modules, and terabytes of storage, creating a distributed platform for low-latency data transfer, secure routing, and edge processing in space.
“Reaching commercial operations at scale is a defining milestone for Kepler,” said CEO and Co-Founder Mina Mitry.
Kepler says its infrastructure can support AI-enabled mission workflows and increasingly autonomous spacecraft by allowing data to be analyzed closer to where it is collected. The network also enables customers to place sensors and applications aboard Kepler satellites while using the company’s integrated connectivity and computing capacity.
That hosted-payload model could play a growing role in the development of orbital data centres. Kepler is already collaborating with Axiom Space, which plans to use the network to enable on-orbit data-centre nodes.
The company has demonstrated space-to-space links, optical tracking between different orbital planes, and connections to more than 10 optical ground stations across multiple continents. Kepler has also completed what it describes as the first commercial demonstration of an optical data relay between low Earth orbit and an aircraft.
A larger expansion is planned for 2028 through several launches, including a dedicated mission aboard Rocket Lab’s Neutron vehicle. The next generation of satellites is expected to increase the network’s capacity and resilience while introducing optical terminals capable of data rates up to 100 gigabits per second.
Kepler has launched 33 satellites to date. As spacecraft generate larger volumes of time-sensitive data, its commercial network points to a broader shift in digital infrastructure: moving connectivity, storage, and computing closer to the source—even when that source is hundreds of kilometres above Earth.
