CASTOR - IMU1640 Tactical Inertial Measurement Unit for Guidance, Navigation and Control Applications
CASTOR - IMU1640
High-Performance Tactical MEMS Inertial Measurement Unit (IMU)
The Castor series IMU1640 is a high-end tactical class inertial measurement unit consisting of high-performance triaxial MEMS Accelerometer, triaxial Gyroscope and triaxial Magnetometer sensors based on latest MEMS technology. The IMU is equipped with a high-speed processor that runs superior signal processing algorithms delivering control grade inertial measurement data. The IMU output is available over a digital SPI interface. Its rugged and modular design makes it suitable for integration with control computers and other application hardware.
The miniature MEMS IMU, CSTR-IMU1640 offers 0.8 deg/hr. bias instability performance and is suitable for inertial guidance and control applications where size is the constraint. The Castor IMU design complies with MIL environmental and EMC standards.
