An over-reliance on GPS/GNSS for positioning, navigation and timing applications underscores key vulnerabilities. Certainly, for defense, security, safety, commerce, and critical infrastructure face these challenges. But geospatial disciplines would be particularly acutely impacted as they rely on higher precision applications than many of these other segments.


The good news is that there are many emerging technologies that show promise as backups and alternatives. This includes efforts to improve the resiliency of GNSS,; this includes the detection and mitigation of jamming and spoofing, providing encryption, and improvements through the modernization of all constellations.


Backups and alternatives to GNSS, as the primary source of PNT, include terrestrial systems, low earth orbit satellites, alternative signals and use of signals of opportunity, and terrestrial paths for precision timing. Geospatial disciplines do not solely rely on the positioning and navigation aspects of PNT. Precision timing is essential for the information technology we take for granted, and has become even more critical as AEC, geospatial, and infrastructure data and workflows further digitalize and move to the cloud.


In this one-day seminar, we examine PNT alternatives and GNSS resiliency technologies, presented by developers and early implementers. You will hear about PNT solutions based on alternate signals, signals of opportunity, light, integrated inertial, alt satellites, and various tech that is also being developed for indoor navigation and positioning.


This free virtual conference experience brings together industry leader, subject matter experts, and innovative practitioners to provide forward thinking and acting geospatial professionals a glimpse of the possibilities to take advantage of this new wave of alternate PNT solutions, tools, and resources.



Professionals and practitioners of the following industries that rely on precise positioning, navigation, and timing:

  • Information Technology

  • GIS and Geospatial

  • AEC, Surveying and Mapping

  • Critical Infrastructure

    • Rail​

    • Air

    • Telecom
