Vertical Reference Unit with Fiber Optic Gyros, MEMS Accelerometers and integrated Strapdown Processor

With iVRU-FC a vertical reference unit is provided for applications which require high accuracy and simple using.


  •  Three rate gyros and three accelerometers
  • < 0.003 deg/s bias stability
  • high shock resistance due to FOG / MEMS technology
  • CAN / RS232 / RS422 / Analog / HDLC interfaces (options)
  • Sync Input / Triiger Output available
  • Integrated L1 GPS receiver as option
  • Odometer interface as option
  • Navigation and Guidance

iVRU-FC is a triaxial system with three orthogonal mounted rugged fiber optic gyroscopes, three ultra ruggedised MEMS accelerometers and an integrated powerful micro-processor with 16 bit sensor data digitalisation to provide digital data transmission (CAN, RS232, RS422) and extended internal error modelling. As an option also analog output data can be provided. As a further optionan internal GPS / magnetometer can be provided as well as a speed sensor interface to achieve higher performance also in difficult environment. Interfaces for platform stabilisation are available on request. Qualification according to MIL-STD-810F and MIL-STD-461E possible on request. The units are available with and without mounting flange (option -FF).

With iVRU-FQ a version with higher performance servo accelerometers is available.
