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.

Features:

• < 0.75 deg/hr / 450 deg/s , 1 mg / 5g or 20 g ; 400 Hz
• higher MTBF than RLG sys­tems
• Interfaces: RS232, RS422 UART, RS422 HDLC, Odometer, GPS (internal or external) [depends on options]
• Stabilisation tasks
• INS/GPS navigation
• Surveying applications
• Guidance and Control
• used in many countries / applica­tions worldwide

The IMU is designed for rugge­dized ap­plications and is internally equipped with shock absorbers. As an option the unit also can be de­livered hard-mounted, i.e. without shock-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. 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 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.
