About ACEINNA
ACEINNA develops MEMS-based inertial and electrical sensing components for autonomous vehicles, robots and industrial equipment. Its OpenIMU modules expose calibrated accelerometer, gyroscope and magnetometer data alongside customisable navigation algorithms, while sealed tilt sensors target construction and agricultural machinery. Integrated INS products combine inertial sensing with dual-band GNSS and real-time kinematic corrections for centimetre-level positioning.
Navigation Studio lets engineers simulate motion, modify estimation code, deploy it to OpenIMU hardware and analyse recorded results. Higher-end systems such as INS401 add triple-redundant inertial sensors and dead reckoning for positioning through satellite-signal interruptions. ACEINNA also produces magnetoresistive current sensors for power conversion and electrified drivetrains, extending its component role from machine localisation into energy monitoring and control.

Timeline
Events
- 2023-06-29 - Partnership - ACEINNA signs global distribution agreement with Avnet
The agreement covered INS, RTK, IMU and current-sensing products. ACEINNA linked the channel to off-road, autonomous and electric-vehicle markets. Avnet described transportation as a priority vertical for the expanded line.
Source - 2018-09-17 - Product Launch - ACEINNA launches OpenIMU development kit for drones, robots and AGVs
ACEINNA describes OpenIMU for drones, robots and AGVs. The launch centered on GNSS-aided inertial navigation software and development hardware. The product supports low-cost precise navigation applications.
Source - 2018-06-19 - Funding - ACEINNA finalises approximately US$50M start-up investment
The company described the capital as a start-up investment rather than a named venture round. ACEINNA was created by the original MEMSIC ownership, management team and board after MEMSIC sold its consumer-sensor business and brand. The financing supported ACEINNA's focus on inertial navigation, medical-flow and current-sensor product lines.
