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
A multi-class, two-axis rate table intended for development, in-process testing, calibration, and final inspection of inertial components and instruments, including high-precision MEMS sensors at FOG performance level, medium and large IMUs, MEMS-class IRUs, stabilized optical sights, and star trackers.
Inner roll axis and outer pitch axis, each with continuous angular freedom.
U-shaped outer-axis gimbal provides unobstructed optical access to the tabletop.
Rate stability is listed as 0.005% (50 ppm) over a 360° interval on both axes.
Designed for R&D and research laboratories, including universities.
The FDA-222-ECO is described by ACCUDYNA as a multi-class, two-axis rate table for development, in-process testing, calibration, and final inspection of inertial components and instruments.
The catalog specifically lists high-precision MEMS sensors at FOG performance level, medium and large IMUs, MEMS-class IRUs, stabilized optical sights, and star trackers among the intended test articles.
The outer-axis gimbal uses a U-shaped design for unobstructed optical access to the tabletop and includes a stow lock to facilitate safe loading and unloading of the UUT.
Mechanical, drive, sensing, and UUT-interface elements stated in the manufacturer catalog.
Two degrees of freedom are provided by the inner roll axis and outer pitch axis.
The catalog describes a highly reliable direct-drive servo system with drive assembly, servo controller, and power amplifier.
An absolute optical encoder is mounted directly to the axis to support high-precision positioning performance.
Pre-loaded angular-contact ball bearings allow load capacities up to 25 kg, with slip rings providing electrical access to the UUT.
