World-first: Quantum optical atomic clock deployed on unmanned sub
The article reports the successful world-first deployment of Infleqtion’s Tiqker quantum optical atomic clock on the Royal Navy’s unmanned testbed submarine, Excalibur (XCal). This trial demonstrated the clock’s ability to operate reliably through multiple dives, providing highly precise timing critical for resilient positioning, navigation, and timing (PNT) in GPS-denied underwater environments. By integrating a compact optical clock with laboratory-grade performance directly onboard, the Tiqker offers a stable “time heartbeat” that reduces navigation drift, enabling submarines to remain submerged, accurate, and covert for longer periods. This deployment aboard the Excalibur, an extra-large uncrewed autonomous vehicle (XLUAV), marks a significant advancement in autonomous underwater operations and reflects the Royal Navy’s trust in Infleqtion as a quantum technology partner. The Tiqker clock also enhances other submarine systems such as sonar, fire control, and secure communications, improving overall mission performance. Given that submarines cannot rely

Researchers at the University of Surrey have developed an AI system called Pose-Enhanced Geo-Localisation (PEnG) that dramatically improves location accuracy in urban environments where GPS signals are often unreliable. By combining satellite imagery with street-level images and using relative pose estimation to determine camera orientation, PEnG reduces localization errors from 734 meters to just 22 meters. The system operates using a simple monocular camera, common in vehicles, making it practical and accessible for real-world applications, especially in areas like tunnels or dense cities where GPS coverage is weak or unavailable. PEnG offers a GPS-independent navigation solution that could significantly enhance the reliability and resilience of autonomous vehicles, robotics, and other navigation-dependent industries such as logistics and aviation. The researchers emphasize that this approach not only improves everyday convenience but also addresses safety concerns linked to GPS outages or interference. Supported by the University of Surrey’s PhD Foundership Award, the team is working on a prototype for real-world testing and has made their research open
