Silicon Sensing Systems Ltd is a market leader in silicon micro electro-mechanical systems (MEMS) gyroscopes, accelerometers and inertial measurement units, focusing on products delivering high performance, ultra-reliability and affordability. The company has supplied tens of millions of MEMS sensors to thousands of customers worldwide. Constantly innovating, all its inertial sensors and systems are based on its unique, patented vibrating ring sensor design - and all sensors are manufactured in the company’s state of the art MEMS foundry in Japan. Silicon Sensing's latest generation of products includes more compact, lower power consumption, precision performance devices that challenge the performance of larger and more power consuming fibre-optic based products. These products have particular application in the tough ocean surface and subsurface environments.

Three Silicon Sensing products have particular relevance to the marine environment. DMU41 is a tactical-grade, 9 degrees of freedom (DoF) inertial measurement unit (IMU). This is a robust MEMS product that operates in temperatures ranging from -40oC to +85oC, delivering exceptional low noise performance, bias instability and angle random walk. Its performance challenges that of typical fibre-optic gyro IMUs in a far more compact package – measuring just 50 x 50 x 50mm, weighing under 180g and consuming less than 2.5w.

The CRH03 is a high-performance/low-noise single axis gyroscope that consumes 30% less power than its predecessor and incorporates improvements in both micro electro-mechanical systems and electronics, with new drive electronics and upgrades to the sensor head. Available in five rate ranges it is highly tolerant to external vibration and delivers excellent bias instability and angle random walk.

For applications such as downhole surveying, platform stabilisation, guidance and control and autonomous vehicles, the high-stability CRS39A MEMS gyro incorporates a move to a single board from two (in the previous generation product). This has reduced the unit's mass by 40%, allowing the device to be more easily installed in space-limited applications such as the 25m cylinders typical to downhole drilling equipment. The CRS39A delivers excellent bias instability, angle random walk and exceptional low noise performance.

The CRH03 is a stand-alone gyro delivering precise inertial sensing performance that is stable over time and temperature. Small, lightweight and rugged, with low power consumption and proven performance, CRH03 is an excellent and cost-effective alternative to FOG and DTG-based products - and is available in both housed and OEM configurations.

For use in severe environments including subsea downhole drilling, the CRS39A includes a move to a single board from two, reducing the unit’s mass by 40% compared to its predecessor. This allows far more easy installation in space-limited applications such as the 25mm diameter cylinders typically used in downhole drilling equipment.
