Aegiverse develops advanced fiber optic gyro (FOG)-based inertial sensing technologies designed for unmanned and autonomous platforms operating across air, land, and underwater domains. Read more >>
Incubated by Taiwan’s National Central University, the company combines commercial off-the-shelf production with in-house R&D to deliver both standard and tailored solutions, supporting clients from initial concept through to system integration and production.
SG-3A-EC Fiber Optic Gyro
Aegiverse’s FOG architecture uses a multi-layered configuration that consolidates optical and electronic components within a single module. This approach achieves measurable reductions in size, weight, and cost, enabling compact, high-accuracy systems suitable for Unmanned Aerial Vehicles (UAVs), Unmanned Ground Vehicles (UGVs), Unmanned Underwater Vehicles (UUVs), and potentially small satellite platforms such as CubeSats.
The company’s SG-3A-EC Fiber Optic Gyro is a single-axis closed-loop design developed to provide precise angular velocity measurement in a compact format.
Measuring 60 by 60 by 72 millimeters and weighing 300 grams, the unit achieves a bias instability of 0.030° per hour and an angular random walk of 0.010° per square-root hour. Its SWaP-efficient construction allows straightforward integration into unmanned platforms and higher-order navigation assemblies such as Inertial Measurement Units (IMUs) and Inertial Navigation System (INS) units.
MU-2A-AC FOG IMU
The MU-2A-AC IMU extends this technology into a six-axis configuration that combines closed-loop FOG gyros with high-grade quartz MEMS accelerometers. The system measures angular velocity, linear acceleration, and orientation for UAVs and other unmanned platforms including UGVs, USVs, and UUVs. Compact and robust, the MU-2A-AC weighs 1.5 kilograms with dimensions of 158 by 140 by 86 millimeters. It provides a gyro bias instability of 0.020° per hour, an accelerometer bias instability of 12 micro-g, and supports consistent long-term accuracy for high-end motion tracking and navigation tasks.
The AR-3A-EC Attitude and Heading Reference System (AHRS) combines two MEMS gyro axes with a single FOG axis and a three-axis accelerometer array. Supported by AI-based algorithms, the system provides precise attitude stabilization and inertial positioning for small to mid-size unmanned vehicles. Compact at 60 by 60 by 72 millimeters and weighing 300 grams, the AR-3A-EC achieves roll and pitch accuracy of 0.020° (1σ) and heading precision of 0.002° within one second. The hybrid configuration leverages MEMS responsiveness and FOG bias stability, delivering Z-axis bias instability of ≤ 0.03° per hour.
Through these developments, Aegiverse delivers inertial sensing solutions adaptable for integration across a range of unmanned and autonomous systems, providing reliable motion data and control performance for next-generation platforms operating in diverse environments.
