IMU inertial system Pulse-40 OEM

for droneITAR-freeminiature

Overview
Pulse-40 OEM is an ultra-compact 9‑DoF inertial measurement unit (IMU) combining tactical-grade inertial performance, integrated vibration intelligence and a SWaP‑C optimized OEM form factor. The unit is ITAR FREE and not subject to export restrictions.

Key features

• Tactical-grade sensing: very low gyro and accelerometer bias in-run instability and low noise.
• High dynamics: gyro range ±4000 °/s and accelerometer range ±40 g for aggressive maneuvers.
• High output rate: up to 2000 Hz (2 kHz) ODR with low-latency streams.
• Integrated vibration intelligence: full-spectrum FFT up to 8 kHz, vibration monitoring and mitigation features.
• Complete 9‑DoF: built-in 3‑axis magnetometer.
• Optimized SWaP‑C: compact footprint 30 × 28 × 13.3 mm, weight 19 g, power ~0.30 W.
• Rugged environmentals: designed for high vibration and shock, compliant with MIL‑STD‑810 and multiple EMC standards.
• Easy integration: binary sbgECom protocol and sbgINSRestAPI for configuration.

Performance highlights
Output Data Rate (ODR): 2000 Hz
Gyro measurement range: ±4000 °/s
Accelerometer measurement range: ±40 g
Gyro latency (motion to output): 1.5 ms

Built-in tools and diagnostics
Onboard vibration monitoring provides full FFT up to 8 kHz and high-level alerts. Each unit undergoes individual multi‑axis thermal calibration. Continuous monitoring and advanced diagnostics safeguard data integrity and enable real-time fault detection.

Applications

• Navigation systems in GNSS‑challenged environments (attitude estimation, dead reckoning).
• Autonomous platforms (UAV, UGV) for localization, navigation and control.
• EO/IR stabilization and payload pointing requiring low noise and high update rates.
• Remote weapon stations and turrets for stabilization and tracking under vibration.
• Precision-guided munitions and seeker stabilization where high dynamics and controlled supply chain are required.

Documentation & integration
Comes with comprehensive online documentation and integration tools. Communication uses binary sbgECom and sbgINSRestAPI for configuration (clock mode, ODR, sync in/out, events) enabling high-bandwidth, low-latency data streams.
