Advancing the Possibilities in Applied Gravimetry.
Our advanced gravimeters are built on our proprietary, in-house designed Vibrating Beam Accelerometer MEMS-based sensor technology, engineered to detect minute gravitational changes with exceptional precision. Providing a practical and cost-effective solution, our technology serves as a bridge between traditional mechanical gravimeters and the emerging potential of larger, high-cost quantum gravimetry.
Technology Focus
MEMS Gravity Sensing
At the core of our gravimeter lies our in-house designed and developed proprietary VBA MEMS-based gravity sensor.
Patented Vibrating Beam Technology
<5 microGal measurements in as little as 60s - precise gravity measurements with ultra-low drift.
Complex MEMS Design & Fabrication
Low cost & high reproducibility through high-precision micro-fabrication with advanced material science.
Miniaturization & Scalability
Lightweight and low power. Unique advantages vs conventional and quantum gravity sensing.
GAIA Physics Core
Vacuum-Sealed MEMS Chamber – Isolates the sensor to maintain ultra-low pressure conditions for enhanced sensitivity.
Ultra Precise Thermal Stability – Eliminates temperature-induced drift for consistent measurements.
Digital Resonance Tracking Unit (DRTU) – Hyper-accurate resonance measurement system, ensuring low-noise, high-resolution output.
Precision Electronics – Custom-designed low-noise amplifiers and signal processing for superior data integrity.
Gravity Alignment Gimbal
Accurate gravity measurements require the sensor to be precisely aligned with the vertical axis. Our fast, compact, remotely operated and highly accurate gimbal system ensures this alignment in any environment and reduces operator based measurement errors.
Milli-degree Precision Control – Ensures the single-axis gravity sensor is always optimally positioned.
Robust & Compact Design – Engineered for field applications, maintaining accuracy under movement and vibration.
Fast Alignment – Rapid levelling (<10s) for efficient deployment and measurement.
High Range – Designs for 5-degree and up to 15-degree levelling ranges.
Software & User Interface
Designed with modern usability in mind, our software and UI are streamlined for data acquisition and analysis as required by modern field surveys and scientific investigations.
Multiple Connectivity Options – USB and Wi-Fi with integrated API as well as redundant SD card storage for flexible data transfer.
Onboard Data Analysis & Corrections – Real-time processing for tide and elevation (Bouguer) corrections.
User-Friendly Interface – Intuitive software for both expert and field users, reducing training time and improving efficiency.

Advantages
Unique MEMS Technology
Orientation-Agnostic measurements
Gravity sensing without strict vertical alignment, supports operation on dynamic platforms - previously not possible with quartz or quantum technologies
Solid-State Resilience
Built from monolithic silicon microstructures, our sensor contains no macroscopic moving parts. The result is high shock resistance, vibration tolerance, and long-term mechanical stability.
Ultra-Compact Sensor Core
With a footprint of only 5 cm diameter our latest GAIA-CORE is orders of magnitude smaller than mechanical or optical systems — enabling lightweight, deployable solutions.
