SBG Systems has released a second-generation Pulse-40 OEM, a miniature tactical-grade IMU aimed at guidance, stabilization, and navigation applications in space- and power-constrained platforms.
The new version keeps the original’s compact footprint — 30×28×13.3 mm, 19 grams, roughly 0.3 W typical power draw — while adding a wider ±4000°/s gyroscope range, integrated three-axis magnetometers for a full 9-DoF output, and motion-to-output latency down to 1.5 ms at data rates up to 2 kHz. The company says gyro bias stability, long-term bias repeatability, and scale-factor accuracy have all been improved over the first-generation unit.
A notable new feature is built-in vibration analysis: the IMU continuously monitors its mechanical environment and outputs a full vibration spectrum from 4 Hz to 8 kHz, including raw FFT data and summarized reports, without external instrumentation. SBG says this is intended to speed up integration, qualification, and troubleshooting for platforms operating in harsh vibration environments. The hardware also adds vibration damping and improved EMC resistance.
The unit is form, fit, and function compatible with the original Pulse-40, so existing integrations can upgrade with limited redesign. SBG’s Gaël Bielecki said the combination of small size, ruggedness, and vibration monitoring targets platforms like guided rockets, precision-guided glide bombs, and loitering munitions, while Head of Product Management Yoann Plenet framed the vibration-monitoring capability as a way to give engineers direct insight into mechanical conditions up to 8 kHz.
The Pulse-40 OEM is available now for evaluation and integration programs.
