Inertial measurement unit Pulse-20

Pulse-20 is the most compact fully calibrated industrial grade 9 Degrees of Freedom (DoF) Inertial Measurement Unit (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 highly robust to environmental constraints, with unmatched survivability in shocks, robustness in vibrations, and maintains outstanding performance in all conditions. Pulse-20 is the best motion sensor for space-constrained applications with tough environmental conditions.Compact and Robust: Ultra-small size, fully calibrated from -40 ºC to +85 °C, ensuring constant behavior in all environments.MEMS Technology: Integrates a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, all factory calibrated, temperature-compensated, and filtered with a tailored FIR filter for outstanding performance.Advanced Connectivity: Supports RS-422 serial and CAN communication for flexible integration across a wide range of applications.Individual Calibration: Each unit undergoes a thorough calibration and testing process across its entire temperature range. A calibration report is delivered with the product.Applications: Suitable for airborne navigation (stable flight control), land navigation (sensor fusion and orientation), AUV navigation, gimbal cameras, pointing & stabilization, SATCOM OTM, and self-driving cars.Key Performance Figures:Gyro bias instability: 7°/hrAccelerometer in-run bias instability: 14 µgPower Consumption: 400 mWVolume: 5 cm³Specifications:Accelerometer:Range: ±40 gLong term bias repeatability: 1500 μg (one year accelerated aging)Bias in-run instability: 14 μg (Allan Variance method, constant T °C)Scale factor: 100 ppmVelocity random walk: 0.03 m/s/√hVibration rectification error: 0.05 mg/g²Bandwidth: 390 HzGyroscope:Range: ±1000 °/sLong term bias repeatability: 750 °/h (one year accelerated aging)Bias in-run instability: 7 °/h (Allan Variance method, constant T °C)Scale factor: 500 ppmAngular random walk: 0.18 °/hVibration rectification error: <1 °/h/g² (10g RMS – random vibrations 20Hz to 2kHz)Bandwidth: 133 HzMagnetometer:Range: 50 GaussBias in-run instability: 1.5 mGaussRandom walk: 3 mGaussBandwidth: 22 HzInterfaces:Output protocols: Binary sbgEComOutput rate: Up to 2kHzSerial ports: 1x RS422, 1x RS232CAN: 1x CAN 2.0 A/B, up to 1 MbpsSync OUT: 1 x Synchronization outputSync IN: 1x Clock InputClock modes: Internal, External Direct (2kHz), External Scaled (1Hz to 1kHz)IMU configuration: sbgECom, sbgCenter (ODR, sync in/out, events)Mechanical & Electrical:Operating voltage: 4 to 15 VDCPower consumption: 400 mWWeight: 10 gDimensions (LxWxH): 26.8 mm x 18.8 mm x 9.5 mmEnvironmental:Ingress protection (IP): IP-50Operating temperature: -40 °C to 85 °CVibrations: 10 g RMS | 20 Hz to 2 kHzShocks: < 2000 gMTBF (computed): 50,000 hoursCompliant with: MIL-STD-810Compatibility: Compatible with SbgCenter software, Robot Operating System (ROS), and Pixhawk autopilot systems.Documentation: Comprehensive documentation is available, including hardware manual and configuration guides.Pulse-20 hardware manualPulse-20 configuration guideTypical Applications: AUV Navigation, Gimbal Camera, Pointing & Stabilization, SATCOM OTM, Self-Driving Cars, Airborne and Land Navigation.Technical Specifications Summary:Accelerometer Range: ±40 gGyroscope Range: ±1000 °/sAccelerometer Bias in-run instability: 14 μgGyroscope Bias in-run instability: 7 °/hVelocity Random Walk: 0.03 m/s/√hAngular Random Walk: 0.018 °/√hAccelerometer Bandwidth: 390 HzGyroscope Bandwidth: 133 HzOutput rate: Up to 1kHzOperating voltage: 4 to 15 VDCPower consumption: 0.40 WWeight: 10 gDimensions: 26.8 x 18.8 x 9.5 mm
