Session E3b: PANEL: Synergistic Services: Fusing PNT and Communications

RETURN TO SESSION LIST

Date: Thursday, September 17, 2026
Time: 10:35 a.m. - 12:15 p.m.
Location: Windsong 3-4

Positioning and timing services within existing wireless communications networks are becoming a vital component of modern PNT infrastructure. Leveraging large bandwidths and widespread deployment, these systems offer high-accuracy alternatives to traditional GNSS. LEO non-terrestrial networks (NTNs) are particularly promising for providing near-global, high-strength, wideband PNT signals. This panel will explore the fundamental tension at the heart of any joint PNT-communications system: PNT favors deterministic, low-entropy signals with high temporal coherence, while communications require randomized, high-entropy data for high throughput. Experts will discuss the present reality and future promise of integrated communications and PNT systems, including techniques to optimize one service while meeting minimum operational requirements for the other. Discussions will span system design, waveform development, resilience to GNSS outages, and spectrum-sharing policies.
