Silicon Sensing has recently launched a number of new products particularly suited to the maritime environment.

DMU41 is a new 9 degrees of freedom (DoF) inertial mea- surement unit (IMU). Measuring just 50x50x50mm and weighing 200g, its volume is 54% lower and weight 42% less than its predecessor. The new CRH03 is a high-perfor- mance/low-noise single axis gyroscope that consumes 30% less power than its predecessor and incorporates improve-
