EMES Inertial Navigation System-Calibration High Accuracy
The product is composed of MEMS gyroscope chips, MEMS accelerometer chips, temperature sensors, digital signal processing circuits, as well as structural and embedded software components. It adopts flexible interconnection technology and integrates advanced compensation algorithms, including full-temperature compensation, installation misalignment compensation, and nonlinearity compensation.
The system is capable of delivering stable and reliable, error-compensated measurement data under static, dynamic, and harsh operating conditions. It is designed to be form-fit compatible with the STIM300 series, enabling seamless drop-in replacement.
