Introducing the U123D: A Cutting-Edge Inertial Measurement Unit
The U123D represents a state-of-the-art inertial measurement unit (IMU) that utilizes fiber optic gyroscope (FOG) technology. Its design is not only ultra-compact but also lightweight, encased in a durable aluminum shell. This advanced unit incorporates three FOGs alongside three MEMS accelerometers, operating efficiently with a power consumption of merely 1.5 Watts. Additionally, it features a fully integrated analog-to-digital converter (ADC) board, complete with RS422 serial interaction capabilities.
Versatile Applications for Unmanned Systems
This non-ITAR IMU is exceptionally suited for various unmanned systems, making it an excellent choice for applications such as inertial navigation in unmanned aerial vehicles (UAVs), unmanned surface vehicles (USVs), unmanned underwater vehicles (UUVs), and drone flight management.
