A Sherbrooke, Quebec-based quantum technology company is set to launch a groundbreaking mission that could fundamentally change how the world navigates without relying on vulnerable GPS satellites.
SBQuantum will deploy its quantum diamond magnetometer aboard a SpaceX Falcon 9 rocket Monday morning, marking a critical step toward developing magnetic navigation systems that could replace GPS in military and civilian applications.
The launch, scheduled for approximately 6:20 a.m. Eastern Time on March 30, represents Canada's entry into the U.S. National Geospatial-Intelligence Agency's MagQuest Challenge. The competition aims to identify advanced technologies capable of monitoring Earth's magnetic field to maintain the accuracy of the World Magnetic Model (WMM), which underpins navigation systems in smartphones, commercial aviation, and military operations.
Growing GPS Vulnerabilities Drive Innovation
The timing of this quantum leap in navigation technology comes as GPS systems face increasing threats from electronic warfare, jamming, and signal spoofing. Recent conflicts have demonstrated how easily adversaries can disrupt satellite-based navigation, making enemy forces appear in different locations or causing civilian aircraft to lose their way.
"GPS signals can simply malfunction or become weak above certain latitudes, like in the Arctic, because no satellites are passing overhead," the company explains, highlighting vulnerabilities that quantum sensors aim to solve.
"Quantum sensing is the next frontier. Our technology has now been validated for the most demanding conditions imaginable, and we are proud to bring to market a device which could soon play a central role in how the world navigates on land, air, and sea."
SBQuantum founder David Roy-Guay emphasized that applications extend far beyond navigation, encompassing defence, resource exploration, and public safety.
Magnetic North Pole Shift Creates Urgency
The need for improved magnetic field monitoring has become more pressing as Earth's magnetic North Pole has shifted position rapidly over the past two decades. Current satellites collecting WMM data are nearing end-of-life and only provide periodic snapshots rather than continuous monitoring.
SBQuantum's quantum diamond magnetometer promises continuous, highly detailed tracking of magnetic field movements. The sensor uses nitrogen vacancy diamonds that leverage quantum properties like superposition and entanglement to detect minute changes in magnetic fields without requiring precise positioning.
This technology enables magnetic navigation that provides reliable readings across all environments, making it particularly valuable for defence and aerospace sectors seeking GPS alternatives in an era of electronic warfare.
Strategic Canadian Capability
The quantum sensing sector has gained recognition as one of Canada's "key sovereign capabilities" under the recently unveiled Defence Industrial Strategy, positioning SBQuantum at the forefront of a strategically important technology sector.
The company is participating in the MagQuest Challenge through a partnership with space data analytics firm Spire Global. The final phase of the competition is expected to conclude this fall, with results informing the National Geospatial-Intelligence Agency's future data collection strategy for the World Magnetic Model.
Beyond military applications, the technology could transform civilian navigation, resource exploration, and scientific research by providing unprecedented precision in magnetic field measurements across diverse environments and conditions.
