Problem
Conventional mapping and navigation sensors such as cameras, radar, and GPS struggle to operate in underground, subsea, indoor, or otherwise GPS‑denied environments, leaving a gap in reliable spatial intelligence for those settings. Existing active sensors are vulnerable to jamming, spoofing, and vibration noise, which reduces data quality and operational security.
Solution
Delta.g develops quantum gravity gradiometers that exploit atom‑interferometer “hourglass” technology to measure tiny variations in the Earth’s gravitational field. By comparing the gravity pull on two vertically separated clouds of cooled rubidium atoms, the device generates a high‑precision gravity‑gradient signal without emitting any radiation. The sensors are completely passive, making them immune to electromagnetic interference, jamming, and spoofing. Their design cancels out vibration and environmental noise, delivering reliable measurements in harsh conditions. The system provides near‑real‑time gravity maps that reveal terrain, structures, and voids where traditional sensors cannot see, supporting navigation and subsurface discovery. Rugged, portable hardware engineered to TRL 7/8 enables deployment on land, sea, and air platforms, and the patented architecture allows future upgrades to higher sensitivity.
Target Audience
Primary customers include defense and security agencies, mining and oil‑&‑gas exploration firms, civil‑infrastructure inspection teams, and autonomous‑vehicle or robotics operators that require accurate mapping and navigation in GPS‑denied or concealed environments.
