Tactical-Grade IMU in Small Form Factor

SBG Systems announced the tactical-grade Pulse-40 inertial measurement unit (IMU) in a miniaturized size for precision and robustness under harsh conditions, with an excellent size, weight, power and cost (SWAP-C) rating for its category.

The Pulse-40 is a 6 degrees-of-freedom, tactical grade IMU integrating micro-electromechanical systems (MEMS) three-axes accelerometers and gyroscopes in a unique redundant design that permits reducing system size while pushing performance level to the maximum.

Among the performance specifications, the Pulse-40 features excellent gyro and accelerometer bias instability of 0.8°/h and 6µg respectively, enabling long dead reckoning and maintaining excellent heading performance.

Thanks to a rigorous selection of sensors featuring extremely low vibration rectification error (VRE), the Pulse-40 can sustain high-vibration environments, up to 10g RMS. Data reliability during operation is also ensured by the embedded continuous built-in-test, enabled by redundant sensor integration. This functionality is a key parameter for critical applications. The Pulse-40 requires no periodic maintenance. An intensive qualification process including accelerated aging guarantees that the sensor behavior is stable over time.

The Pulse-40 comes with a 2-year warranty. It is export license-free and ITAR-free.

SBG Systems has a long-term history of designing quality MEMS-based inertial navigation systems (INS). Extensive research in signal processing, micro-electronics, calibration algorithms, and sensor qualification have won the company a reputation for accuracy and reliability since 2007. Its sensor calibration and validation tools, initially based on a single axis motion simulator with a temperature chamber, have evolved over the years and are now based on 100% automated, multi-axis motion simulators with temperature chambers. The high level of automation mitigates human error risk and ensures that all the delivered products meet their specifications.

SBG Systems is an ISO 9001:2015 certified company.
