Ocean Business 2023

• Latest generation of sensors and systems offer new performance levels for smaller and longer endurance maritime platforms.
• Visit us on stand E8, April 18^th – 20^th.

At Ocean Business in Southampton, UK, this month Silicon Sensing will exhibit its latest generation of inertial systems and sensors that combine extended performance with significant reductions in unit size, weight and power consumption.

David Somerville, General Manager, Silicon Sensing comments: “These products offer a new level of precise, sustained motion sensing to the most compact surface and subsea platforms and applications.  Their low size, weight and power consumption will also help deliver valuable gains in the operational endurance of any platform.”

The display at the show will include:

• The DMU41 - the highest performing silicon MEMS (micro electro-mechanical systems) inertial measurement unit (IMU) on the market today. This is a non-ITAR, tactical grade inertial measurement unit (IMU). Measuring just 50x50x50mm, weighing less than 200g and with low power consumption, it delivers a performance that competes directly with heavier, larger, and more costly, fibre optic gyro-based products. DMU41 is ideal for space-limited applications such as remotely operated vehicle control and navigation and for complex activities such as ocean surveying and mapping.
• The CRH03 - a high performance, stand-alone gyro suited to tasks such as maritime platform stabilization, guidance and control and precision surveying. Also non-ITAR restricted, and with low power consumption, CRH03 incorporates new drive electronics and improvements to the sensor head that make it highly tolerant to external vibration and able to deliver comparable bias characteristics to FOG (fibre-optic gyros) and DTG (dynamically tuned gyros). It is available in five rate ranges, including a new option of 10 degrees per second.
• The CRS39A - a gyro developed for use in applications such as downhole drilling and north finding. Another non-ITAR product, this upgrade has moved to a single board from two to reduce volume by 40%, allowing it to be installed more easily in space-restricted applications such as the 25mm diameter cylinders used in downhole drilling equipment. Upgraded micro electro-mechanical systems (MEMS) and electronics deliver improved bias instability, angle random walk and noise and vibration tolerance whilst multiple on-board temperature sensors mean performance can be specifically tuned to the rigours of the most extreme operating environments.

David Somerville continues: “With each of these new devices we are bringing new choices and opportunities to operators in the marine sector, where there is a constant drive for increased precision, over longer time frames and in ever-more extreme surface and subsurface conditions.”
