How it works
Gravity is universal, inescapable, and impossible to mask. Our sensors treat it as a truth signal. By comparing tiny differences in gravity across space, our sensors uncover what’s hidden: terrain, structures, voids, all without emitting a trace.
At the core is our patented hourglass technology, stacking two atom interferometers vertically. Inside each “bulb” are clouds of cooled rubidium atoms. As the sensor passes over hidden features, each cloud experiences a slightly different pull of gravity. A perfect laser ruler tracks these changes, recording interference patterns that act as gravity’s fingerprint.
Totally passive
We design our sensors to be completely passive. They read only the natural gravitational field, nothing is emitted, or transmitted so it operates quietly, invisibly, and without interference.
Noise-immune
Think of our sensor like noise-cancelling headphones. Our “hourglass” design uses two atom clouds, held apart and measured with a laser. This allows the sensor to cancel out vibration and noise, leaving only the true gravity gradient signal. No other commercial device achieves this.
Instant insights
Where other technologies need long settle times or heavy post-processing, we’re working towards sensors that are ready to measure as soon as they’re switched on providing real time intelligence.
Patented architecture
Delta.g’s core technology is protected by granted patents. Developed through world-first demonstrations and now advanced under UK Department for Transport contracts, the system is engineered for portable, rugged field deployment at TRL7/8.
Scalable sensitivity
Our sensor’s sensitivity isn’t capped. As our technology evolves, the same patented design can be engineered to deliver ever-higher precision, so today’s device can grow into tomorrow’s tool for navigation and subsurface monitoring.
