BlueHalo achieves key milestone in space-based laser communication technology

The demonstration showcased two optical terminals completing critical functions including pointing, acquisition and tracking at operational power levels. These tasks were successfully performed under simulated space conditions such as extreme temperatures, vibration (jitter), and vacuum environments.

BlueHalo’s system enables high-bandwidth, secure data transmission between satellites across multiple orbits—LEO, MEO, GEO and beyond—at faster rates and longer distances than current technologies. With the technology now validated at Technology Readiness Level 6, it is considered ready for near-term deployment.

Mary Clum, President of BlueHalo’s Product & Space Systems division, praised the team’s work and confirmed the company is prepared to begin production for operational satellite use. She noted the capability is “orders of magnitude greater” than existing on-orbit systems and essential to meeting growing defence and commercial data demands.

The advanced optical terminals are designed for a wide range of applications, offering extended range, improved accuracy, and enhanced reliability. The technology builds upon earlier BlueHalo systems already deployed in orbit, further reinforcing the company’s position in the evolving space communication landscape.
