The iIMU-FSAS is a very small size IMU con sisting of 3 fiber optical gyros (FOG) in closed-loop technology of class 0.75 deg/hr and 3 servo-accelerometers of class 1 mg.
The IMU is designed for rugge dized ap plications and is internally equipped with shock absorbers. As an option the unit also can be de livered hard-mounted, i.e. without shock-ab sorbers. The iIMU-FSAS can be oper ated on a unregulated wide range input supply voltage and is protected against wrong polarity and moder ate over-volt age. The data output can be trig gered 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 proc essor and with odometer in ter face. All sig nals are fed via an robust connector of type MIL-C-38999-III.
The iIMU-FSAS is manu fac tured in Ger many and can be used in many commercial and defense applica tions as a replacement for Litton’s LN-200 or Hon eywell’s HG1700/1900 in surveying applications. Com pared to HG1700 the iIMU-FSAS has more than 10 times higher MTBF.
