iVRU-CB-M: Inertial Measurement System with integrated Strapdown Data Fusion with Odometer Interface and integrated L1 GPS
Vertical Reference Unit with MEMS Gyros, MEMS Accelerometers, Odometer I/F, integrated GPS and Strapdown Processor
With iVRU-CB-M a vertical reference and navigation unit / IMS with integrated L1 GPS engine and advanced 15+ state Kalman filter based data fusion is provided for applications which require medium accuracy and simple using.
The iVRU-CB-M is a triaxial system with three orthogonal mounted MEMS gyroscopes, three MEMS accelerometers, GPS engine and an integrated powerful micro-processor with high resolution sensor data digitization to provide digital data transmission (CAN, RS232, RS422) and extended internal error modelling. As a further Option an external GPS / magnetometer can be provided as well as an integrated speed sensor interface to achieve higher performance also in difficult environment.
