About SMG

SMG (Silicon MicroGravity) develops high-precision MEMS inertial and gravity sensors based on proprietary resonant MEMS technology. Its sensors deliver high accuracy, compact design, and low power consumption for autonomous navigation, aerospace, defence, robotics, and subsurface exploration. SMG Motion focuses on low-drift accelerometers and gyroscopes for inertial navigation, tilt sensing, and seismology; SMG Gravity targets better than 5 µGal gravity measurements for subsurface and space exploration. Backed by over a decade of Cambridge-origin research and a growing patent portfolio, SMG commercialises resonant MEMS that compete with quartz-based solutions on Size, Weight, Power, and Cost (SWaP-C).
