From Arctic sovereignty patrols to maritime and autonomous operations, the vulnerability and limitations of GPS present a critical gap in Positioning, Navigation, and Timing (PNT) capability. One of the most promising solutions to this challenge is magnetic navigation (MagNav) — exploiting high-resolution maps of Earth’s crustal magnetic field as a stable, passive geophysical reference. Unlike GPS, the Earth’s magnetic field cannot be jammed, spoofed, or denied.

ZeroDrift Technologies is a US magnetic navigation solutions company headquartered in Cambridge, Massachusetts. Using Diamond Quantum Magnetic technology, we’ve developed a comprehensive and scalable solution to the limitations and vulnerabilities inherent in GPS. Combining proprietary sensors, machine learning software, multi-platform deployability, and a scalable mapping pipeline, our approach dramatically improves upon current solutions and supports cost-effective global mapping. By partnering with ZeroDrift Technologies, public sector and commercial customers obtain a faster-to-deploy and more precise alternative to GPS navigation.
