Chess Dynamics, part of the Cohort plc Group, has upgraded the EOSS-D (Electro-Optical Surveillance System-Digital) system, the latest evolution of Chess Dynamics’ electro-optical surveillance technology.
EOSS-D introduces a modern, fully digital architecture, enhanced sensor options, and integrated AI-enabled video tracking. Modular and portable, it also retains the proven reliability and compact form factor of the original designs trusted by operators worldwide.
The enhanced EOSS-D is designed to meet the growing surveillance and targeting demands of today’s complex, multi-domain threat environment, whether that be for land (Hawkeye EOSS-D) or maritime (SeaEagle EOSS-D) applications.
The system integrates Ethernet-based control in place of legacy interfaces, streamlining connectivity and seamless integration into command-and-control networks. It is also backwards compatible with many legacy Cobra-based systems, providing a clear and cost-effective upgrade path for existing users.
Mark Byfield, Managing Director at Chess Dynamics, stated, “EOSS-D represents a new standard in EO surveillance. It gives customers a step-change in capability without sacrificing the size, portability, and reliability they value. By combining a proven platform with modern digital architecture and AI-enabled tracking, we’re giving operators sharper eyes, smarter tracking, and easier integration, all in one package.”
The EOSS-D platform is based on Chess’ analogue SeaEagle EOSS system, in service since 2011, and utilises its widely deployed Cobra positioner. Its fully digital system architecture replaces legacy analogue interfaces with a single Ethernet connection, simplifying installation, enabling remote control from virtually any location, and ensuring adaptability to future mission profiles and sensor technologies.
