Qartia Smart Technologies SL works on the digital transformation of defense and security operations through advanced sensing and monitoring technologies. It delivers solutions to enhance troop training, monitor soldiers in combat, enable predictive maintenance of rotating machinery in naval vessels and combat vehicles, and develop Digital Twins for military infrastructure (e.g., training facilities). Qartia provides robust, ATEX-certified systems for harsh and hazardous environments. It has developed a secure IoT communication infrastructure using LoRa, WiFi, and 5G for real-time data acquisition and mission-critical visualization. As a key innovation, Qartia deploys decentralized, non-cellular 5G wireless networks to enable video-based, high-performance IoT in remote or infrastructure-limited areas. It also integrates AI modules with advanced spatio-temporal algorithms for predictive situational awareness, boosting safety, efficiency, and decision-making in both strategic and tactical defense scenarios.
