Portable Gravimeters for Resource Exploration, Infrastructure, Aerospace and Defence.

SMG is transforming subsurface detection and mapping with next-generation gravity sensing technology. Our advanced gravimeters deliver rapid, stable, high accuracy measurements in a compact, robust and efficient design, making them ideal for traditional geophysical surveys including resource exploration, construction, infrastructure and volcanology as well as new applications including defence, aerospace and alternative navigation.
Mineral & Resource Exploration
Accurately uncovering the planet’s hidden resources through detailed gravity surveys. Our technology provides highly accurate, portable, and non-invasive measurements enabling cost-effective subsurface analysis while minimizing environmental impact and reducing survey times. Suitable for exploration of mineral deposits, hydrocarbons and geothermal anomalies.
Construction & Infrastructure
Faster, more cost-effective projects with enhanced subsurface insights. Our gravity instruments help identify buried utilities, detect sinkholes, assess ground stability and monitor changes in critical infrastructure, enabling engineers and urban planners to avoid costly mistakes, optimize trenching, and ensure structural integrity.
Aerospace, Alt-Nav and Space Exploration
Advancing planetary science and navigation both on Earth and beyond. For the first time, highly accurate, compact, low-power, and robust gravity sensing technology suitable in high and low g applications is available for planetary surface mapping, alternative navigation, and asteroid resource prospecting.
Military & Defence
Enhancing defence and security intelligence with high-accuracy gravity sensing. Our field-portable and autonomous vehicle ready passive gravimeters are able to detect underground bunkers, tunnels, and landmines, providing critical subsurface intelligence for combat, counterinsurgency and border control operations. Our technology also offers new avenues for alternative navigation in GNSS denied environments
Products & Technology.
Pioneering Technology for 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. Utilising this unique and patented technology we can provide a practical and cost-effective solution for modern gravity measurements. Our technology serves as a bridge between traditional gravimeters and the emerging potential of larger, higher-cost quantum gravimetry.
