The iIMU-FSAS-NG 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. It is the form-fit-function successor of the well-known iMU-FSAS, but consumes about 4 W less power, comes with optionally slightly lower enclosure height and proides fully compatible mechanical and data interfaces.
For users of NovAtel's SPAN technology, the version iIMU-FSAS-NG-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 accurate surveying and navigation applications and therefore contains no integrated vibration absorbers. 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.
The iIMU-FSAS-NG 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-NG has more than 10 times higher MTBF.
If the application requires a full INS/GNSS/ODO data fusion, see our iNAT-FSSG System Family.
