Innovative MEMS Inertial Sensors Unveiled by Silicon Sensing at Ocean Business 2021

At the Ocean Business 2021 exhibition, Silicon Sensing has announced the launch of cutting-edge MEMS-based inertial sensors. Among these advancements are the company’s top-tier silicon MEMS Inertial Measurement Unit (IMU) adn a series of new compact gyroscopes.

Introducing the DMU41: A Game-Changer in IMU Technology

The DMU41 stands out as a non-ITAR, high-performance IMU, measuring a compact 50x50x50mm and weighing under 200 grams. This model boasts a 54% reduction in volume and a 42% decrease in weight compared to its predecessor, the DMU30, while also significantly lowering power consumption. These enhancements allow the DMU41 to deliver performance that rivals larger, heavier, and more expensive fiber optic gyro (FOG)-based systems. It is designed for ultra-precise motion detection in marine applications,including control and navigation for unmanned underwater vehicles (UUVs) and autonomous underwater vehicles (AUVs),and also for high-accuracy surveying and mapping tasks.

CRH03: Compact Gyro for Enhanced Maritime Stability

The CRH03 is a newly developed compact single-axis gyro tailored for maritime platform stabilization, guidance, control, and precision surveying. Also free from ITAR restrictions, the CRH03 consumes 30% less power than its predecessor, the CRH02. It features upgraded drive electronics and sensor head improvements, making it highly resistant to external vibrations while providing bias characteristics comparable to FOG and dynamically tuned gyros (DTGs). The gyro is available in five rate ranges, including a new option that supports 10 degrees per second.

CRS39A: Robust Performance in Extreme Conditions

Designed to withstand the harshest environments, the CRS39A gyro is an enhanced version of the established CRS39 unit. It achieves a 40% reduction in volume by transitioning from a dual-board to a single-board design, facilitating installation in space-constrained applications. The upgraded MEMS technology and electronics have led to significant improvements in bias instability, angle random walk, and noise and vibration resistance. Additionally, multiple onboard temperature sensors enable the gyro’s performance to be finely tuned for extreme operating conditions.

Commitment to Innovation in marine Technology

Steve Capers, General Manager of Silicon Sensing, expressed pride in the engineering team’s efforts to develop these significant new non-ITAR products.He stated, “We are excited to present these innovations at Ocean Business. Each product offers essential new options for marine operators, who continually seek enhanced and sustained performance in challenging surface and subsurface environments. We eagerly anticipate showcasing our complete range of inertial sensors and systems to both existing and prospective clients at the event.”
