We are pleased to introduce the latest generation of our Pulse-40 OEM, a miniature tactical-grade Inertial Measurement Unit (IMU) designed to meet the growing demands of compact defense, aerospace, and autonomous systems. This new version builds on the original Pulse-40 platform with improvements in inertial performance, environmental resilience, production scalability, and embedded diagnostics, while preserving the ultra-compact design and low power consumption that made the sensor a reference in its class.
Navigation and guidance systems continue to shrink. Manufacturers must maximize performance without increasing size, weight, or power. The new Pulse-40 OEM meets this challenge. It combines tactical-grade inertial sensing with improved resistance to vibration and electromagnetic interference. Our IMU measures just 30 × 28 × 13.3 mm, weighs 19 grams, and typically consumes only 0.3 W.
Enhanced performance for high-dynamic applications
The latest generation introduces several improvements aimed at increasing measurement accuracy and long-term stability. Enhanced gyroscope bias stability, improved scale factor accuracy, and better long-term repeatability contribute to more consistent performance in demanding operating environments.
The new Pulse-40 OEM introduces a ±4000°/s gyroscope range, doubling the maximum angular rate of previous high-range models. The expanded dynamic range accurately captures extremely fast rotational motion. It supports demanding applications such as guided rockets, precision-guided glide bombs, loitering munitions, and other high-dynamic platforms. The sensor also now integrates three-axis magnetometers, providing a complete 9-degree-of-freedom sensing solution without increasing its footprint.
The defense market is increasingly looking for navigation and stabilization solutions that fit into smaller platforms without compromising performance” said Gaël Bielecki, Business Development Manager – Defense at SBG Systems. He proceeds to state that: The new Pulse-40 OEM delivers exactly that combination. Its unique blend of tactical-grade performance, vibration resilience, low SWaP, and integrated vibration monitoring makes it particularly well suited for guided rockets, precision-guided glide bombs, loitering munitions, and next-generation optronic systems operating in demanding environments.
Beyond measurement accuracy, SBG Systems has focused on improving responsiveness. The Pulse-40 OEM features a redesigned processing architecture capable of delivering motion-to-output latency as low as 1.5 milliseconds, with output rates reaching 2 kHz. The reduced latency enables faster control-loop updates for stabilization, navigation, and guidance systems where rapid sensor feedback is essential.
Built for harsh environments
Environmental robustness has also received significant attention. The new IMU incorporates an integrated vibration damping system that improves immunity to high-frequency mechanical disturbances, while an updated electrical design enhances resistance to electromagnetic interference. Together, these improvements help preserve inertial performance in operating conditions where vibration and EMI can negatively affect sensor accuracy.
One of the most distinctive additions to the new Pulse-40 OEM is its integrated vibration monitoring capability. In addition to delivering inertial measurements, the sensor continuously analyzes its mechanical environment and generates a real-time vibration spectrum covering frequencies from 4 Hz to 8 kHz.
Engineers can access FFT data and summarized vibration reports directly from the IMU during integration and testing. They no longer need external instrumentation. The feature reveals valuable insights into platform dynamics. Engineers can identify vibration sources, validate mechanical designs, accelerate qualification campaigns, and simplify troubleshooting throughout the system lifecycle.
Many of our customers operate in environments where vibrations and electromagnetic disturbances can be just as challenging as achieving the required inertial performance” said Yoann Plenet, Head of Product Management at SBG Systems. He continues, stating: “The new Pulse-40 OEM addresses both challenges. This new platform is more resilient to harsh operating conditions, and its unique vibration spectrum monitoring feature gives engineers direct insight into the vibration environment up to 8 kHz. This not only helps preserve navigation performance but also dramatically simplifies integration, testing, and troubleshooting.
Seamless upgrade path and production scalability
While introducing a new hardware platform, we have maintained full compatibility with existing Pulse-40 integrations. The new version preserves the same mechanical footprint and integration philosophy, allowing our customers to upgrade with minimal redesign while benefiting from improved performance and diagnostics.
The redesigned architecture also supports greater manufacturing efficiency, enabling us to scale production for larger deployment programs without compromising the consistency and quality expected from tactical-grade inertial sensors.
Our new Pulse-40 OEM is available immediately for evaluation and integration into guidance, navigation, stabilization, and autonomous systems. By combining higher inertial performance, enhanced environmental resilience, ultra-low latency, and built-in vibration intelligence, we further strengthen the Pulse family as a leading solution for mission-critical applications where size, weight, power, and reliability are paramount.
