Aceinna Inc. is a fabless semiconductor company specializing in advanced MEMS-based sensing solutions. Headquartered in Andover, Massachusetts, USA, it was originally the sensor division of ACE Controls before becoming an independent entity. The company focuses on developing high-performance inertial measurement units (IMUs), GNSS-aided navigation systems, current sensors, and pressure sensors for automotive, industrial, robotics, and agricultural applications. Its flagship product lines include the IMU380 series of 6-DOF inertial measurement units, the RTK330 GNSS/INS precision navigation system, and the MCR series of current sensors using proprietary AMR technology. Aceinna’s pressure sensors, such as the MPS series, deliver high accuracy in harsh environments, leveraging bulk-silicon MEMS technology. The company is known for its low-noise, temperature-stable sensor designs that enable precise motion control and positioning. Aceinna holds a competitive edge in the niche MEMS sensor market, offering integrated solutions that combine hardware with advanced calibration and fusion algorithms. While not a top-tier semiconductor giant, it is recognized for its innovation and reliability in mission-critical sensing applications. The company distributes worldwide through direct sales and authorized distributors, continually expanding its product portfolio to address emerging autonomous system needs.
