SBG – Pulse 40
Pulse-40 IMU is a miniature tactical-grade Inertial Measurement Unit that embeds low noise gyroscopes and accelerometers to deliver optimal performance in applications where precision and robustness matter in all conditions.
It has been engineered with redundant sensor design that improves data robustness, as it performs continuous built-in-test (CBIT). This make our IMU ideal for critical applications.
| Features | |
| Pulse-40 is a miniature, 6 degrees of freedom (6DoF), tactical grade Inertial measurement unit (IMU), designed for a wide range of applications, that delivers unmatched performance in harsh conditions, with no compromise on SWaP.
Based on a redundant integration of MEMS accelerometers and gyroscopes, Pulse-40 features a unique set of benefits for a so small inertial measurement unit. It has low sensor noise, high bandwidth and high data rate that are perfectly aligned with stabilization applications requirements. Our IMU is tailored for vibrating environments, thanks to an ultra low Vibration Rectification Error (VRE) and a robust aluminum enclosure. |
|
| Small but highly robust | With its compact size, Pulse-40 provides a constant behavior in all environments thanks to its extensive calibration from -40° to +85°C. It is also resistant to shock and vibrations < 2 000g. |
| Excellent SWaP ratio | Pulse-40 IMU achieves the tactical grade while maintaining a smart balance of performance in a 12-gram and 0.3 W sensor. It is particularly suited to use by integrators. |
| ITAR Free – no export restriction | Pulse-40 is designed and manufactured in France, and has no export restriction. |
| +15 years of expertise | For more than a decade, thousands of inertial sensors have been delivered to our customers all around the world. |
