iMAR iVRU-FC-FC, Triaxial Sensor Cube with Fiber Optical Gyros
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. The system is qualifyed according to MIL-STD-810F and MIL-STD-461E incl. 50 ms hold-over for power drops according to DO160E. The units are available with and without mounting flange (option -FF).

technical data iMAR iVRU-FC-FF:
Vertical Reference Unit with Fiber Optic Gyros, MEMS Accelerometers and integrated Strapdown Processor.
iVRU-FC is an attitude heading reference system designed for stabilization and attitude heading reference tasks. It comes as an option with a fixation flange (iVRU-FC-FF).
* Three rate gyros and three accels
* < 0.003 deg/s bias stability
* high shock resistance due to FOG / MEMS technology
* CAN / RS232 / HDLC interfaces
* Sync Input / Output available
* Navigation and Guidance
iVRU-FC is a three axes system containing rugged fiber optic gyroscopes, three MEMS accelerometers and as an option one incremental encoder interface for turret angle feedback or vehicle velocity measurement.
The system provides digital data transmission (CAN, RS422, RS232). Additionally, the system can be connected with an external GPS engine (NMEA GGA / VTG / HDG and PPS signal input).
Optionally, the system contains an internal L1 GPS receiver already. As a further option an external magnetometer can be connected.
Qualification according to MIL-STD-810F and MIL-STD-461E.
iVRU-FC-FF provides a grounding bush; a GORE membrane vent is standard for all units.
The power supply is protected against voltage drops, overvoltage and high voltage lightning.
The iVRU-FC-FF is free of export license requirements.
