Canada’s first positioning, navigation, and timing resilience framework identifies 10 areas for potential action, from national coordination to interference testing. Announced on October 22, 2026, the PNT Resilience Framework addresses the services that establish location, guide movement, and synchronize equipment.
The framework combines civilian and defense requirements. Its proposed measures include a national PNT office, preparedness planning, interference monitoring, and infrastructure risk management. Other priorities cover sovereign timing and geodetic infrastructure, satellite and terrestrial capabilities, sensor fusion, and open-air testing against jamming and spoofing. These are potential measures, rather than a list of fully funded deployments.
Timing Is a Separate Infrastructure Requirement
Satellite navigation also supplies time to systems that remain stationary. The United States National Institute of Standards and Technology describes how PNT services support infrastructure: GPS timing helps synchronize telecommunications and timestamp financial transactions, alongside its transportation applications.
A timing receiver can serve a network that has no need to determine its location. Its job is to give distributed equipment a shared time reference. Losing that reference can affect coordination between machines even when their communications links remain available. This timing market is part of the commercial demand for resilient navigation examined by New Space Economy.
Canada already distributes official time through the National Research Council. Its Network Time Protocol service uses atomic-clock-controlled servers at two locations on different networks. The arrangement provides redundancy for network and maintenance outages.
Internet time transfer also illustrates why distribution matters as much as the reference clock. The protocol compensates for some network delays, but congestion and variable transmission times affect accuracy. The NRC reports that local networks can achieve accuracy of a few milliseconds; performance over larger networks is less predictable. Different applications consequently need different delivery methods and performance specifications.
Combining Sources and Detecting Interference
The Canadian framework calls for complementary technologies suited to Arctic, remote, coastal, and other operating environments. Satellite services, terrestrial signals, and local sensors can contribute different capabilities. Sensor fusion combines measurements from several sensors to produce an estimate.
The document distinguishes jamming, which prevents use of a signal, from spoofing, which supplies false information. That distinction affects testing: equipment must be assessed for incorrect outputs as well as missing ones.
NIST’s Foundational PNT Profile provides a concrete example of operational risk management. It helps organizations identify PNT-dependent systems and assets, select appropriate services, detect disruption or manipulation, and manage the resulting risks. This work begins with understanding which equipment depends on an external reference and how that dependence affects operations.
A second receiver does not necessarily provide a separate source. Two devices may depend on the same satellite signals or upstream timing service. Identifying that shared dependency is part of determining whether an alternative will remain useful during the disruption being considered.
The framework’s proposed test ranges would support validation under jamming and spoofing conditions. The documented next step is further engagement and development of initiatives, with additional information to be published as that work advances.
