Silicon Sensing participated in Geo Business London, which took place from 4–5 June, showcasing its DMU41, CRH03, and DMU11 compact inertial sensors, all developed for precise motion sensing in geospatial applications.
The company was among more than 130 exhibitors and highlighted how its high-performance sensor solutions are being utilized in various geospatial projects.
These compact systems offer a combination of low size, weight, and power consumption with reliable, long-term accuracy, enabling precise motion tracking in space-limited environments.

The DMU41 is a 9 degrees of freedom (DoF) inertial measurement unit (IMU) that provides a level of performance comparable to larger, heavier fibre optic gyro-based IMUs. Measuring 50 x 50 x 50mm, the unit delivers stable operation across a wide temperature range, with very low noise, excellent bias stability, and superior angular random walk characteristics.
Specifications:
- Operating temperature: -40°C to +85°C
- Power consumption: 1.8W
- Bias Instability: 0.1°/hr, 0.015mg
- Random Walk: Angular – 0.02°/√hr, Linear – 0.05m/s/√hr
The CRH03 is a single-axis gyroscope that offers accuracy on par with fibre optic gyros. It is built to withstand vibration and maintain consistent bias performance. It features five selectable rate ranges, including a 10°/s option, and is available as either an OEM module or a complete packaged product.
Specifications:
- Operating temperature: -40°C to +85°C
- Bias Instability: 0.03° to 0.1°/hr
- Angular Random Walk: starting from 0.005°/√hr
- Rate Ranges: ±10°/s up to ±400°/s
In addition to newer offerings, Silicon Sensing continues to provide established solutions such as the DMU11. This 6 DoF IMU is a compact and economical choice suited for both smaller and larger system integrations. It delivers low-noise operation with consistent performance in terms of bias and random walk.
Specifications:
- Operating temperature: -40°C to +85°C
- Random Walk: Angular – 0.40°/√hr, Linear – <0.05m/s/√hr
- Bias Instability: <10°/hr, <0.05mg
- Noise: Gyroscope – 0.1°/s rms, Accelerometer – 1mg rms
With attendance exceeding 4,000 participants, the event created opportunities for valuable conversations with both existing clients and potential users, further emphasizing the growing role of inertial sensor technology in geospatial applications.
Darioosh Naderi, Global Strategy Lead, commented, “This was our first time exhibiting at this event and we were hugely impressed with the quality of the discussions we had. Our team was presented with an extraordinary range of opportunities which were a fit for our inertial technology. We look forward to returning next year.”
