Silicon Sensing

Silicon Sensing is a leading developer of high-performance MEMS silicon gyroscopes, accelerometers and inertial systems. The company’s next-generation, compact and lightweight products provide ultra-precise motion sensing capabilities for demanding marine and maritime applications, enabling enhanced guidance, stabilisation, navigation and control for both surface and sub-surface platforms.

All of Silicon Sensing’s products are ITAR-free, and offer FOG-like performance in a significantly reduced SWaP (size, weight and power) footprint.

DMU41

High-performance MEMS IMU for marine applications

The tactical-grade DMU41 IMU (inertial measurement unit) provides a cost-effective alternative to larger FOG-based systems, providing cutting-edge motion sensing capabilities in a package that is more than 40% more SWaP-efficient than its predecessor. The high-precision MEMS sensor incorporates three inductive and three piezoelectric resonating ring gyroscopes, six capacitive accelerometers and three magnetometers.

Delivering angular rate and linear acceleration data with exceptional ARW, bias and noise characteristics, it is ideal for a wide range of marine platforms including survey vessels, submersibles and AUVs/ROVs.

DMU11

Low-SWaP MEMS IMU for high-volume production

The DMU11 is a low-cost board-level IMU with a minimal physical footprint, making it ideal for OEMs and systems integrators. Combining MEMS inertial angular rate and linear acceleration sensors to provide a six degree-of-freedom solution, it strikes an optimal balance between price and performance.

The sensor has been fully calibrated over the entire operational temperature range, and is highly suited to providing motion sensing and tracking in three dimensions for the smallest vessels and platforms operating in harsh and dynamic ocean-going conditions.

CRH03

Single-axis analog gyro with low noise

The CRH03 is a single-axis MEMS gyroscope that outputs high-accuracy angular velocity data with comparable bias characteristics to bulkier and more expensive FOG- and DTG-based sensors. Based on Silicon Sensing’s state-of-the-art resonating ring gyroscope technology, the gyro features low noise and incorporates a built-in temperature sensor that allows the unit to be precisely configured according to changes in environmental conditions.

The CRH03 is available in five dynamic ranges, and can be provided as an OEM board or in a robust enclosure.

CRS39A

Single-axis MEMS gyro for stabilization, guidance and control

The CRS39A is a single-axis MEMS gyroscope in a compact and lightweight board-level form factor, featuring excellent performance in bias instability, angle random walk and noise as well as enhanced vibration tolerance. It includes two onboard temperature sensors that allow the unit to be fine-tuned according to environmental conditions, improving performance even further.

The miniature MEMS gyro sensor is designed to be mounted within a 25mm inside diameter cylinder, and is ideal for stabilization of marine vessels and offshore platforms, as well as for guidance and control of undersea vehicles.

Pinpoint

Ultra-miniature MEMS gyros for navigation and pointing

The PinPoint series features the smallest MEMS gyroscopes in the Silicon Sensing product portfolio, delivering excellent bias performance and noise over temperature characteristics in an ultra-miniature hermetically-sealed ceramic LCC surface mount package.

The sensors provide both analog and digital outputs, and offer user-selectable dynamic ranges and bandwidth options. The PinPoint gyro is available in two versions, measuring angular velocity about an axis either perpendicular or parallel to the PCB.
