IMU with Low ARW, Trigger, Integrated Power Regulation

The iIMU-FCAI-03 is a small size IMU con sisting 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
  • higher MTBF than tactical RLG based systems
  • Stabilisation tasks
  • INS/GPS navigation
  • Surveying applications
  • Guidance and Control

The IMU is designed for ruggedized applications in surveying and control. The iIMU-FCAI-E-03 can be operated on a unregulated wide range input supply voltage and is protected against wrong polarity, EMC and moderate overvoltage. The data output time stamp can be triggered and the data are sent via UART RS422 or RS232. As an option the system can be delivered with an additional integrated odometer interface. All signals are provided via an robust connector of type MIL-C-38999-III. 

The iIMU-FCIA-E-03 is manufactured in Germany. The version with angularrate < 500 deg/s and acceleration < 10 g does not require an export license (“-E” version).
