First interoperability of laser links in space
York Space Systems in the US has completed the first laser communication links between different suppliers in low Earth orbit (LEO).
The tests connected a Tranche 0 Transport satellite built by York with a Tranche 0 Tracking satellite built by SpaceX, representing a significant milestone in space-based communication.
This demonstration is a key step to build an extensive LEO constellation built by multiple vendors to a common interface standard. Successfully closing this laser communication link between vendors and across two network layers and orbital inclinations shows how the standardized Optical Communication Terminal (OCT) protocol enhances interoperability.
The demonstration of the Proliferated Warfighter Space Architecture (PWSA) is part of the Space Development Agency (SDA) in the US.
“This breakthrough reflects York’s leadership in advancing interoperable technologies that ensure resilience and innovation in space networks,” said Dirk Wallinger, CEO of York. “Achieving the first inter-vendor, inter-layer laser link demonstrates the tangible value of open standards and collaborative efforts in rapidly achieving an integrated space architecture. We are proud to support SDA’s vision for an interconnected space architecture for the warfighters.”
The S-CLASS, LX-CLASS, and largest M-CLASS platforms developed by York in Denver, Colorado, cater to a diverse set of missions ranging from ISR, remote proximity, weather, to communications and are compatible with a broad spectrum of launch vehicles and ground station providers.
