The Pulse-40 IMU is a compact, tactical-grade inertial measurement unit designed to deliver exceptional precision and robustness for marine, subsea, and vehicle navigation systems operating in extreme environments. Featuring redundant MEMS gyroscopes and accelerometers, it ensures ultra-low noise, high bandwidth, and rapid data rates essential for stabilization and control tasks.
With continuous built-in-test (CBIT) and an ultra-low Vibration Rectification Error (VRE), the Pulse-40 maintains reliable, high-integrity outputs even under intense vibration, shock (<2000 g), and temperature extremes, making it an ideal choice for critical marine and offshore missions.
Weighing just 12 grams with a minimal 0.3 W power draw, Pulse-40 achieves an outstanding SWaP (Size, Weight, and Power) profile without compromising tactical-grade performance. Extensively calibrated from -40°C to +85°C and housed in a rugged aluminum enclosure, it integrates seamlessly into USV and subsea navigation platforms where size constraints, export-free sourcing (ITAR-free), and robust, long-term precision are operational priorities.
