  • Calibration procedure
    We at iMAR Navigation have our own calibration lab (several 2-axes and 3-axes turntables with temperature chamber) and an in-house Vibration/shock test facilities. We also operate a Motion Simulator to apply real ship coning Motion (angle and translatoral motions!) and to test our stabilization platforms in house in Germany.

  • Typical application
    geographical surveying, naval vehicle control, dynamic positioning, drilling, photogrammetry, geo-referencing, LIDAR and laser scanning on airborne and land vehicles, platform stabilization, defence applications, UAV and AUV navigation, autonomous vehicle control, INS/GNSS applications with down to centimeter Level accuracy. iMAR also offers data fusin with image processing, radar / lidar etc., e.g. for vehicle control and monitoring.
  • Distinguishable features
    highest time stamping accuracy (1 µsec) for all signals due to internal extended FPGA based processing, supported by powerful ARM architecture. The Systems are available with all kind of sensor technology (RLG, FOG, HRG) to assure best performance under all environment conditions (even under strong temperature gradients and vibration, where common FOG based systems are showing strongly degraded Performance). High configuration flexibility compared to other systems like SPAN (NovAtel TM). Data logger capability with internal 32 GByte SD memory.
  • Export restrictions
    no ITAR restrictions (only standard dual-use for all gyro compassing systems as usual); simplified EU001 procedure applicable.
