ATLAS

Inertial Measurement Unit

TÜBİTAK SAGE is the leading establishment of Turkey of experience in guided missile technology. ATLAS IMU is a high performance high accuracy IMU. It’s electronic hardware designs, software designs, mechanical designs, algorithm and calibration designs were done by TÜBİTAK SAGE.

ATLAS IMU is designed to meet the needs of navigation, guidance and control applications. It provides a very high input range and excellent long-term repeatability. ATLAS IMU can be successfully used on a wide range of weaponry, military, air, marine and land applications such as stabilized platforms, mission critical platforms, guided missile systems, unmanned aerial vehicles (UAVs). Also, it is suitable for commercial applications. It includes three close-loop fiber optic gyroscopes, three Accelerometers and associated electronic and optical designs which are all environmentally sealed in rugged housing. ATLAS IMU has different variants according to the technical specifications.

ATLAS IMU simplifies system integration by offering many configurable features such as mechanical dimension, gyro performance, accelerometer performance, vibration isolator, power input, data rate, data communication protocol so that it gives greater flexibility in systems design and integration.
