SBQuantum to Launch Diamond Quantum Magnetometer for MagQuest Challenge
Summarize this article with:
SBQuantum to Launch Diamond Quantum Magnetometer for MagQuest Challenge SBQuantum is scheduled to launch a diamond quantum magnetometer into space on March 30 as part of the final phase of the MagQuest Challenge. Led by the U.S. National Geospatial-Intelligence Agency (NGA), the competition is designed to identify technologies capable of monitoring Earth’s magnetic field to maintain the World Magnetic Model (WMM). The launch is conducted in partnership with Spire Global, which provides the satellite infrastructure and data processing capabilities. This mission follows hardware validation and testing at NASA’s Goddard Space Flight Center to ensure the sensor’s functionality in orbital environments. The technical objective of the sensor is to provide continuous, high-precision monitoring of magnetic field vectors using nitrogen-vacancy (NV) centers in synthetic diamonds. This quantum sensing approach allows for a miniaturized form factor—approximately the size of a quart of milk—while maintaining the sensitivity required to track the accelerating shifts in Earth’s magnetic field. The WMM is a foundational component for commercial aviation routing, maritime navigation, and consumer smartphone applications. The current satellite infrastructure used for WMM data collection is approaching the end of its operational life, necessitating the deployment of new sensing arrays to ensure data continuity. Beyond geomagnetic monitoring, the deployment explores the viability of magnetic navigation as a resilient alternative to GPS. Because magnetic signals are localized and independent of satellite-based positioning, they provide a navigation method that remains functional in environments where GPS signals are degraded or contested. The results of this flight phase, expected in late 2026, will inform the NGA’s acquisition strategy for operational magnetic data collection capacity, targeted for 2030. The project aligns with broader defense strategies, such as Canada’s Defence Industrial Strategy, which categorizes quantum sensing as a sovereign technical capability.
