Aeron Systems offers the Castor IMU 1100, a miniature Inertial Measurement Unit (IMU) designed to provide control-grade inertial data for guidance, navigation, and control applications. The unit combines compact dimensions with rugged construction, supporting integration into size-constrained defense platforms.
The Castor IMU 1100 is a high-end IMU comprising triaxial MEMS accelerometer, triaxial gyroscope, and triaxial magnetometer sensors based on the latest MEMS technology. These sensors are paired with a high-speed processor that runs signal processing algorithms to deliver control-grade inertial measurement data.
Output data is available via an RS422 interface, enabling communication with control computers and other application hardware. The unit features a rugged and modular design, making it suitable for integration across a range of embedded systems. The design complies with MIL environmental and EMC standards for operation in demanding conditions.
The CSTR-IMU1100 variant provides bias instability performance of approximately 1°/hr (typical), supporting inertial control applications where compact size is a primary constraint.
Performance and Functional Capabilities
The IMU1100 provides high-end tactical gyroscope performance, with in-run bias instability typically around 0.7 deg/hr. Thermal compensation and short-term turn-on to turn-on repeatability support consistent operation.
Configurable digital filtering with programmable taps allows the unit to be optimized for specific application requirements. Each unit is fully calibrated at the factory for misalignment, offsets, and scale factor errors, with temperature compensation applied to maintain measurement accuracy.
The system supports update rates of up to 2000 Hz, with configurable bandwidth to match application needs. It is designed for shock survival up to 1500 g, supporting use in high-dynamic environments.
A low supply voltage requirement allows operation from low-voltage battery systems. The accelerometer and gyroscope sensors provide low noise and stable performance for high-quality sensor data. The unit operates across a wide temperature range, with sensor compensation ensuring consistent performance throughout.
Interfaces and Integration
The Castor IMU 1100 features an RS422 interface and supports external triggering, diagnostics, and data-ready outputs. These capabilities enable synchronization with user controllers and facilitate integration into larger subsystems.
Applications
The Castor IMU 1100 is suited to guidance, navigation, and control applications requiring compact, rugged, and high-performance inertial sensing.
