01 / AXES
Roll + Pitch Gimbal
Two degrees of freedom are provided by the inner roll axis and outer pitch axis.
- Inner axis: Roll
- Outer axis: Pitch
- Continuous angular freedom
- U-shaped outer-axis gimbal
- Stow lock for safe UUT loading and unloading
A multi-class, two-axis rate table for development, in-process testing, calibration, and final inspection of inertial components and instruments, designed to simulate both vibration and precise slow motion while maintaining high pointing accuracy.
Designed for high-dynamic applications with ±2,000°/s² no-load acceleration on the outer pitch axis.
Inner roll and outer pitch axes, both with continuous angular freedom.
Rate stability is listed as 0.0005% (5 ppm) over a 360° interval on both axes.
Nonlinear multi-variable controller and user-friendly GUI are embedded in a 36U standard console.
The FDA-222-HD is described by ACCUDYNA 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 and large IMUs in the MEMS class, stabilized optical sights, and star trackers among the intended test articles.
The product is designed to simulate both vibration and precise slow motion while maintaining high pointing accuracy, with emphasis on user-friendliness and high-dynamic customer needs.
