SG-IMU
Navigation-Grade Inertial Measurement Unit
SG-IMU (Navigation-Grade Inertial Measurement Unit) provides acceleration and angular rate information to navigation systems of all types of land, air and sea vehicles, mainly guided ammunition.
ITAR-free Fiber Optic Gyro (FOG) technology, navigation-grade quartz accelerometers and related electronic and optical designs are all included in the SG-IMU which is enclosed in a tough-environmentproof structure. Electronic hardware designs, mechanical designs, software and algorithms are all developed by TÜBİTAK SAGE.
