York Space Systems Achieves First-Ever LEO-LEO Laser Link Between Vendors for PWSA | PR Newswire [Video]

, /PRNewswire/ — York Space Systems (York), the Denver-based aerospace company dedicated to the rapid deployment of complete space mission solutions, has successfully completed the first low Earth orbit (LEO) inter-vendor laser communication link for the Proliferated Warfighter Space Architecture (PWSA). This groundbreaking achievement 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 realizes another important step in Space Development Agency’s (SDA) achieving its vision of an extensible and proliferated 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 validates SDA’s decision to adopt a standardized Optical Communication Terminal (OCT) protocol to enhance interoperability. By enabling seamless communication across platforms, this approach ensures interoperability, enhances a competitive marketplace and fosters innovation across the entire space industry.
