THIS PRODUCT IS REPLACED BY iIMU-FSAS-NG (FULLY COMPATIBLE, BUT UP TO 4 W LESS POWER CONSUMPTION)
The iIMU-FSAS is a very small size IMU consisting of 3 fiber optical gyros (FOG) in closed-loop technology of class 0.75 deg/hr and 3 servo-accelerometers of class 1 mg.
For users of NovAtel's SPAN technology, the version iIMU-FSAS-EI-SN is provided. It is directly supporting the SPAN interface, a cable to connect it with NovAtel's ProPak (TM) can be provided on request.
The IMU is designed for surveying applications as well as for ruggedized applications. The IMU does not contain internal vibration isolators to guarantee a best and stable alignment to the user's application. If operated in extensive vibration environment, the user can mount the iIMU-FSAS on external vibration absorbers if desired. The iIMU-FSAS can be operated on a unregulated wide range input supply voltage and is protected against wrong polarity and moderate over-voltage. The data output can be triggered and the data are sent via RS422 on an HDLC protocol or via RS232 / RS422 UART.
All signals are fed via an robust connector of type MIL-C-38999-III.
If a full INS/GNSS/ODO navigation capability or AHRS functionallity is required, see our product line iNAT-FSSG.
The iIMU-FSAS is manufactured in Germany and can be used in many commercial and defense applications as a replacement for Litton’s LN-200 or Honeywell’s HG1700/1900 in surveying applications. Compared to HG1700 the iIMU-FSAS has more than 10 times higher MTBF.
For new designs, we recommend to use our iIMU-FSAS-NG, which has about 4 W less power consumption and where the enclosure has slightly smaller height (but regarding mounting flange and data interface it is fully form-fit-function compatible):
