iNAV-FMS-DA: Inertial Fiber Optic Gyro Navigation System with Dual-Antenna GNSS based True Heading, 0.1 deg/sqrt(hr); not covered by export control
Inertial Measurement System with Fiber Optical Gyros, 0.1 deg/sqrt(hr)
THIS PRDUCT IS NOT RECOMMENDED FOR NEW APPLICATIONS.
It is replaced by the products iNAT-FSSG-1 and iTraceRT-F40x
iMAR's inertial measurement system iNAV-FMS-E-DA for inertial control, stabilization, guidance, tracking and dynamic analysis is equipped with high precision multiplexed fiber optical gyros, servo accelerometers and dual-antenna GNSS and covers applications like navigation, guidance, stabilisation or dynamic control, which require high accuracy in attitude and true heading, 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 evaluation tasks an internal data storage on silicon-disk is available. 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 Windows 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 system is is provided as iNAV-FMS, but with additional dual-antenna GNSS 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.
