The iIMU-FSAS-HP is a very small size IMU consisting of 3 fiber optical gyros (FOG) in closed-loop technology of class 0.1 deg/hr and 3 servo-accelerometers of class 1 mg. It is fit-function to the well-known iMU-FSAS and iIMU-FSAS-NG (those with 0.75 deg/hr) and comes with only 12 mm more enclosure height and provides fully compatible mechanical and data Interfaces.
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. As an option the system can be delivered with an additional integrated AHRS or navigation processor and with odometer interface. All signals are fed via an robust connector of type MIL-C-38999-III.
The iIMU-FSAS-HP is manufactured in Germany and can be used in many commercial and defense applications as a performance improved replacement for Litton’s LN-200 or Honeywell’s HG1700/1900 in surveying applications. Compared to HG1700 the iIMU-FSAS-HP has more than 10 times higher MTBF.
