New IMU - rugged, precise inertial sensing for the smallest platforms (sponsored)
The new DMU41 silicon MEMS IMU
Silicon Sensing’s new DMU41 – the highest performing silicon MEMS IMU available today is also more than 40% smaller and lighter, with 50% lower power consumption.

DMU41 - the highest performing silicon MEMS IMU available today - is packaged in a unit that is approaching half the size, weight and power consumption of its predecessor. This new IMU will bring precision inertial sensing to even smaller and more restricted platforms, operating in the severest environments.
Silicon Sensing Systems has developed a new 9 degrees of freedom (DoF) inertial measurement unit (IMU) which extends the class-leading performance of its predecessor, the DMU30, whist delivering a dramatic reduction in volume, weight and power consumption.
Steve Capers, General Manager, Silicon Sensing Systems Ltd, explains: “We have developed the DMU41 in close consultation with customers across many market sectors, including defence and autonomous vehicles. Many expressed a need for a highly compact, ‘tactical grade’ IMU that is not ITAR (International Traffic in Arms Regulations) controlled.”
At only 50x50x50mm, and weighing just 200g, the new DMU41 has a 54% lower volume and weighs 42% less than the DMU30. In addition, its power consumption is half the typical usage of DMU30.
This new, ultra-compact micro electro-mechanical systems (MEMS) IMU will also extend the performance of the DMU30, to deliver the inertial sensing performance equivalent to far heavier, larger and more costly, fibre-optic gyro-based IMUs. This combination of small size and power consumption with impressive performance, all packaged in a rugged MEMS unit, will bring precision motion sensing to a new range of applications including the smallest and most restricted surface and sub-surface platforms.
The DMU41 – the highest performing silicon MEMS IMU available today
Steve Capers continues: “Our new IMU will find a home operating in the most demanding situations - such as the military and unmanned vehicles markets, where consistent, ultra-precise motion sensing is critical but available space and power are typically very limited. In fact, the potential applications are so many and varied that we look forward to being surprised by interest from unexpected quarters!”
DMU41 is an all-silicon MEMS IMU that delivers unparalleled inertial performance, combining excellent angle random walk and bias stability with exceptional low noise characteristics. The 9 DoF unit combines best-in-class sensors, including three inductive and three piezoelectric resonating ring gyroscopes, and six capacitive accelerometers - all designed and manufactured at Silicon Sensing’s own foundry. It also includes 3 magnetometers to introduce a new layer of data refinement and deliver even greater flexibility and uses the latest high-performance processors.
Data from all the inertial sensors is fully blended to ensure the platform benefits from optimal motion sensing information, with DMU41 able to deliver data at variable output rates up to 2kHz. Outputs can combine angular rate, acceleration, delta angle and delta velocity, temperature, and built-in test results, with every DMU41 calibrated over the full operational temperature range to guarantee sustained, reliable performance.
