PANEL: BEYOND GNSS: EMERGING TRENDS IN LEO-BASED SATNAV AND SIGNALS OF OPPORTUNITY FOR PNT 
(Presentations by invitation only)
As a signal of opportunity, Wi-Fi has provided 10-meter positioning accuracy for billions of users this past decade. The emerging Wi-Fi round-trip time (RTT) standard will provide 1-meter accuracy that will be a game changer for indoor positioning. Likewise, the location capabilities currently being incorporated into 5G standards will serve a major role in UAV and autonomous vehicle applications. The rapid deployment of LEO-based mega constellations for broadband has given us a myriad of signals from space with unprecedented availability and frequency diversity. Early research has shown that these signals can be used effectively for navigation. Furthermore, several entities are working on LEO-based constellations that are purpose built for PNT. Together, these technologies represent the exciting future of radionavigation-based technologies for PNT. They promise to augment the pros and overcome the cons of GNSS. Our panel of experts will describe these technologies, their expected performance, challenges yet to overcome, and when we can expect operational capabilities.
