Chess Dynamics Advances Trusted Surveillance System With New Upgrade

Chess Dynamics, part of the Cohort plc Group, has announced the upgrade of EOSS-D (Electro-Optical Surveillance System-Digital), the latest evolution of Chess Dynamics’ electro-optical surveillance technology.

Building on 17 years of operational success, 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.

“EOSS-D represents a new standard in EO surveillance,” said Mark Byfield, Managing Director at Chess Dynamics. “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.”

Proven pedigree, digital core

The EOSS-D platform is based on Chess’s analogue SeaEagle EOSS system (in service since 2011) and the 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.
