PRODUCT OVERVIEW

High-dynamic inertial testing.Temperature-controlled environment.

ACCUDYNA describes the FDA-222-TCC-HD as a multi-class, two-axis rate table intended for development, in-process testing, calibration, and final inspection of inertial components and instruments.

The catalog specifically identifies high-precision MEMS sensors at FOG performance level, medium IMUs, and MEMS-class IRUs among the intended test articles.

The model combines inner and outer axes with a liquid carbon dioxide (LCO2) temperature chamber. The outer axis includes a stow lock to facilitate safe loading and unloading of the UUT.

ACCUDYNA highlights a nonlinear multi-variable controller and user-friendly GUI embedded in a 36U console, direct-drive brushless torque motors, and high-dynamic performance including 1,500°/s² acceleration on the outer axis.
