MEMS Dual-Axis Angular Rate Sensor for Navigation and Mapping
Product Overview
This dual-axis MEMS gyroscope features proprietary MEMS technology combined with drive pickup circuitry, temperature sensing, digital signal processing, and specialized software. It provides real-time measurement of angular rates along two horizontal axes, delivering compensated angular rate data via RS-422 serial interface.
- High precision dual-axis angular rate measurement
- Comprehensive error compensation including temperature, misalignment, nonlinearity, and zero bias
- Compact, lightweight design with excellent impact resistance
- Superior electromagnetic interference resistance
- Reliable operation in harsh environmental conditions
- Ideal for attitude control applications including stabilized sighting systems and satellite communication antenna control
