iVRU-BB-P

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

With iVRU-BB-P a vertical reference unit / IMU is provided for applications which require medium accuracy and simple using.

Features

  •  Three MEMS based rate gyros and three accelerometers (+/- 180 deg/s, 4 g)
  • < 0.002 deg/s bias stability (short term, const. temp) and 0.2 deg/s over temperature range (OTR)
  • CAN / RS232 / RS422 interfaces (options)
  • Sync Input / Trigger Output available
  • Integrated L1 GPS receiver as option (or external GPS engine)
  • Odometer interface as option
  • Navigation, Guidance and Control

VRU-BB is a triaxial system with three orthogonal mounted MEMS gyroscopes, three MEMS accelerometers and an integrated powerful micro-processor with 20 bit sensor data digitalisation to provide digital data transmission (CAN, RS232, RS422) and extended internal error modelling. 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. 

With iVRU-FQ a version with higher performance (fiber optic gyro based) is available.
