Why Canada should pay attention to Iridium’s new anti-spoofing navigation chip

The global navigation systems that underpin modern society are facing a growing threat. GPS jamming and spoofing incidents are increasing in frequency, affecting everything from commercial aviation and maritime transport to telecommunications infrastructure and financial networks. Against this backdrop, a satellite communications company has declared the commercial availability of a new Positioning, Navigation and Timing (PNT) application-specific integrated circuit (ASIC), a miniature chip designed to provide resilience against GNSS disruption.

The news comes from a company, although headquartered in the U.S., has operations in Canada: Iridium Communications Inc, which is a global mobile satellite services company providing voice, data, and IoT connectivity anywhere on Earth, including poles, oceans and airways, via 66 active satellites. In 2024, Iridium introduced Project Stardust, a 3GPP standard-based satellite-to-cell phone service focusing on messaging, emergency communications and IoT for devices like cars, smartphones, tablets and related consumer applications.

A growing problem for navigation systems

Global Navigation Satellite Systems (GNSS), including GPS, have become fundamental to the modern economy. They guide aircraft and ships, synchronise telecommunications networks, support banking transactions, enable emergency services, and underpin countless industrial processes.

The problem is that GNSS signals are relatively weak and vulnerable to interference. Deliberate jamming can block signals altogether, while spoofing can trick receivers into believing they are somewhere else. Recent high-profile incidents have highlighted how these attacks are moving from theoretical concerns to operational realities. Iridium points to the May 2026 in-flight jamming incident involving UK Defence Secretary John Healey as an example of how navigation disruption can create real-world safety risks.

The economic consequences could be severe. A study sponsored by the U.S. National Institute of Standards and Technology estimated that a prolonged GPS outage could cost the U.S. economy around $1 billion per day in 2019 dollars, equivalent to more than $1.3 billion per day in 2026 terms.

Canada, with its highly interconnected economy and large-scale dependence on transportation and communications infrastructure, would not be immune to similar disruption.

The newly released chip measures just 8 mm by 8 mm and weighs less than 0.2 grams. Despite its small size, it provides an independent source of positioning and timing information by using the Iridium satellite constellation rather than relying solely on conventional GNSS signals.

According to Iridium, the chip receives cryptographically secured timing and location data through one-way satellite transmissions that can continue functioning in environments where traditional GNSS signals become unreliable. The company says its signals can penetrate structures and operate in contested environments where interference is common.

This approach represents a shift in thinking. Rather than replacing GPS, the technology is intended to continuously validate whether GPS-derived information can be trusted. In other words, it is less about navigation accuracy and more about navigation assurance.

That distinction is becoming increasingly important as critical systems move toward greater automation.

Canada: Robotics and autonomous vehicles

For Canadians, resilient navigation has a particular relevance. The country possesses the world’s second-largest land mass, thousands of kilometres of coastline and extensive Arctic territories. Reliable positioning and timing are vital for aviation operations across northern routes, maritime transport in increasingly active Arctic waters, pipeline management, telecommunications networks, mining operations, forestry activities, and emergency response systems.

The Arctic dimension is especially noteworthy. As climate change alters shipping patterns and increases geopolitical interest in northern routes, dependable navigation becomes strategically important. Interference with satellite-based navigation systems in these regions could have consequences extending beyond commercial inconvenience.

Canada has also become a major player in unmanned systems, robotics, and autonomous vehicles. These are industries where confidence in position data is essential. Autonomous aircraft, remotely operated vehicles, drones, and industrial automation platforms all depend on trusted positioning sources.

One particularly interesting aspect of the Iridium announcement is the involvement of Solace Communications, a company with strong Canadian roots. Solace is integrating the Iridium PNT ASIC into its Vector family of assured PNT products. According to the company, the platform combines Iridium PNT, multi-band GNSS, inertial sensing, LTE communications and satellite messaging to create confidence-scored navigation solutions.

Adam Elcock, co-founder of Solace Communications, argues that future systems must move beyond simply reporting a location. Instead, they must determine whether that location data can actually be trusted. That philosophy reflects a broader trend emerging across navigation and cyber-resilience sectors. Increasingly, organisations are recognising that resilience requires redundancy, verification and continuous assessment rather than reliance on a single technology source.

Although navigation receives most public attention, timing resilience may be the more significant issue. Financial markets, power grids and telecommunications networks all rely on extraordinarily precise timing to operate correctly. Even small inaccuracies can create service disruptions, security concerns or regulatory issues. Iridium specifically highlights timing assurance as a major capability enabled by the new chip.

For Canada’s banking sector, electricity infrastructure and telecommunications providers, technologies that reduce dependence on a single timing source could become increasingly attractive as cyber threats grow more sophisticated.
