iIMU-FCAI: Inertial Measurement System with low ARW Gyros and Accelerometers

13. Februar 2012

iIMU-FCAI / iVRU-FCAI: IMS with Low ARW, Trigger, Integrated Power Regulation

iMAR has launched a version of its well-known iIMU-FCAI, which comes up with an extended EMI/EMC protection and slightly rearranged connector position.

iIMU-FCAI is a small size IMU con­sisting of 3 low-noise fiber optical gyros (FOG) in closed-loop technology of class 1 deg/hr and 3 servo-ac­celer­ometers of class 2 mg.

  • 1 °/hr, 2 mg, 200 Hz
  • low ARW, < 0.03 °/ sqrt(hr)
  • exceptional short time bias sta­bility of < 0.02 deg/hr and 10 µg
  • odometer interface
  • better MTBF than tactical RLG based sys­tems
  • Used for:
    - Stabilization tasks
         - iIPSC: Camera and Antenna Stabilization
         - iSSMC: Ship Stabilization and Motion Control, Heave Compensation
         - Heave Compensator, Ride Control, Auto Pilot Applications
         - Dynamic Positioning Applications (DP, DP3)
         - Surge, Sway, Heave Measurement and Compensation Systems
    - INS/GPS navigation
    - Surveying applications
    - Guidance and Control
  • iVRU-FCAI: same architecture, but additional integrated AHRS processor
