iNAV-FMS: Inertial Fiber Optic Gyro Navigation System, class 0.75 deg/hr
Inertial Measurement System with Fiber Optical Gyros, 0.1 deg/sqrt(hr)
iMAR's inertial measurement system iNAV-FMS for inertial control, stabilization, guidance, tracking and dynamic analysis is equipped with high precision multiplexed fiber optical gyros and servo accelerometers and covers applications like navigation, guidance, stabilisation or dynamic control, which require high accuracy, bandwidth, reliability and an open interface. As an option the system provides interfaces for speed measurement (counter input), external marker and trigger. Possible outputs are RS232/RS422, CAN, Ethernet or/and analog output (other on request). Furthermore for surveying or evaluation tasks an internal data storage on silicon-disk is available. Special adaptation of housing and mechanical dimensions is possible. Data processing (strapdown algorithms, attitude and heading calculation, dead-reckoning navigation, coarse northseeking, in-flight-slave-alignment or motion monitoring and control) inside of the measuring system is as well possible as data transmission of pure or corrected raw data. The system can be operated from a PC under WindowsTM using iMAR's NavCommand software or as a stand-alone device. Furthermore an open user-interface is available using iMAR's XIO standard so the user can operate the system from his own environment. Features like "virtual measurement point" are standard, an odometer input is available as an option. Sampling rate and bandwidth of iNAV-FMS are much higher than in competitive IMUs.
With iNAV-FMS-E-DA the same system is provided, but with additional dual-antenna GMSS based heading determination, which allows drift free heading output also at zero and low speed motion. Because iNAV-FMS-E-DA is also free of export control and not covered by ITAR, it is used also as replacement for higher cost ring laser gyro based systems.
