This panel session will explore how the defence sector is enhancing Positioning, Navigation, and Timing (PNT) by developing alternatives to GPS, such as inertial sensors, celestial navigation, and low Earth orbit satellites. These technologies aim to ensure reliable PNT information even when GPS is unavailable. However, integrating these technologies and ensuring their reliability presents challenges. Addressing these issues requires common standards, improved modelling, and prioritization of alternative PNT solutions.
In secure communications, Quantum Key Distribution (QKD) and advancements in steganography are leading the way. QKD uses quantum mechanics for secure channels, while new steganography algorithms enable hidden communications. Overcoming distance limitations in QKD and practical implementation of steganography remain hurdles. Additionally, sophisticated cyber threats add complexity. Developing scalable quantum communication infrastructure and fostering international collaboration are critical needs.
Timing technology has advanced with microelectromechanical systems (MEMS), improving accuracy and resilience. Ensuring synchronization, addressing traditional limitations, and managing environmental impacts are ongoing challenges. Continued innovation and robust synchronization protocols are essential for advancing precision timing.
