Factory-calibrated MEMS accelerometer and gyroscope modules for guidance, navigation, and control applications.
Tactical-Grade MEMS Sensor Modules
Aeron's Castor family of Inertial Measurement Units delivers control-grade inertial sensor data for platforms that need reliable, factory-calibrated acceleration and angular-rate measurement — not a full navigation solution. Each module combines high-performance triaxial MEMS sensors with a high-speed onboard processor running digital signal processing and calibration algorithms, so every unit ships characterized and compensated for bias, misalignment, scale-factor error, and temperature drift.
The family spans a full 6DOF accelerometer + gyroscope + inclinometer module (IMU 1100), a dedicated gyroscope-only module for angular-rate-only applications (GYR 1200), and an OEM PCB-mounted 6DOF module built for high-speed SPI integration (IMU 1640) — giving system integrators the right sensor grade and interface for guidance, navigation, and control computers, robotics, gimbal stabilization, and unmanned ground and aerial platforms.
How Every Castor Module Works
IMU 1100, GYR 1200, and IMU 1640 all run the same onboard calibration and signal-processing approach — only the sensor suite and interface change between them.
Engineered for Control-Grade Precision
