IMU inertial system Pulse-20

MEMS3-axisnavigation

Pulse-20 is the most compact fully calibrated industrial grade 9 DoF IMU. With its sub-miniature design, it can be integrated in multiple different types of vehicles, from civilian and subsea navigation to defense applications. It is also very robust to environmental constraints, with unmatched survivability in shocks, robustness in vibrations and maintains outstanding performance in all conditions. Pulse-20 is, therefore, the best motion sensor for space-constrained applications with tough environmental conditions.Discover all its features and applications.Features:Engineered to maximize the capabilities and performance of MEMS technology in a compact form factor.Integrates a 3-axis accelerometer and a 3-axis gyroscope, carefully calibrated, temperature-compensated, and filtered with a tailored FIR filter for outstanding performance in harsh conditions.Includes a 3-axis magnetometer for full nine-degree-of-freedom measurements.Supports both RS-422 serial and CAN communication for flexible integration.Small-size and highly robust: Ultra-small size, provides constant behavior in all environments thanks to extensive calibration from -40 ºC to +85 °C.Built-in Magnetometer: Factory calibrated, 3-axis magnetometer. Advanced calibration tool calibrates soft and hard iron and aligns the inertial and magnetic frames.Individual calibration process: Thorough calibration and testing process across its entire temperature range. Calibration report guarantees that the product meets specifications and is delivered with the product.Advanced connectivity: Serial RS422 and CAN, enabling integration in a large range of applications.Key Performance Numbers:Gyro bias instability: 7°/hrAccelerometer in-run bias instability: 14 µgPower Consumption: 400 mWVolume: 5 cm³Applications: The Pulse-20 provides precise attitude and heading data in a compact, high-performance package suited for a wide range of applications.
