Precision Gravity Sensing for Subsurface and Space Exploration
SMG’s GAIA MEMS gravimeter offers better than 5 µGal resolution, detecting minuscule variations in gravitational fields. With automatic levelling and compensation for temperature, pressure and tides, it enables high-fidelity, cost effective measurements for mineral exploration, tunnel detection, site surveys, environmental monitoring, and space-based gravitational studies. GAIA’s compact form factor, low power consumption, and wireless connectivity make it suitable for drone deployment, vehicle-mounted surveys, and permanent installations.
MEMS Accelerometers and Gyroscopes.
MEMS sensors for inertial navigation, tilt sensing, and seismology
SMG offers low drift, low noise, high accuracy and sensitivity accelerometers and gyroscopes manufactured in silicon utilising their resonant silicon MEMS technology. We deliver navigational grade specifications with a technology that is scalable in cost, size, weight, and power. With headline performance figures of bias instability below 0.15µg and bias error over temperature below 15µg for the 25g range device. SMG is offering two products within the initial launch, a 25g and 100g range - both variants supplied in a 30mm x 30mm module assembly.
