Calibration of Inertial Sensors

 

Thanks to our modern equipped inertial laboratory at University of Bundeswehr, we can offer the full calibration service for all IMU classes, i.e. from the MEMS-grade until the navigation grade.

 

Laboratory Equipment:

Hardware

  • Three Axis Motion Simulator (Turntable) from Acuitas AG (fig. 1)
  • Incl. CO2 temparture chamber with temperature range between -60 C° and +100 C° 
  • Reference gravity with  an accuracy of 8 µGal (~8.10^-7 m/s²).
  • Reference  north direction with an accuracy of  1 arcsec measured by a GYROMAT-Instrument
  • Decoupled pillar under the turntable to cancel out the surrounding vibration

Software

  •    LabView-Software package with:
  •    predefine calibration routines, such as Six-Position-Static test or turn rates, are available
  •   Automatic report generator allows a flexible calibration procedure.

Offered Service:

 

  • Calibration of all constant/ deteministic error parameters, such as constant bias, scale factor or non-othogonalities, of any IMU
  • Temperature calibration
  • Performance assement of AHRS and INS, for example in term of north-finding or alignement
