Silicon Sensing joined over 130 exhibitors at Geo Business in London, 4–5 June, showcasing how the company’s high-performance inertial sensors are currently enabling many projects in the geospatial sector.
Several products were the focus of discussions at the show. These combine low size, weight, and power consumption with impressive, sustained performance over time. They offer ultra-precise motion sensing to the most compact platforms.
DMU41
The DMU41 is a 9 degrees of freedom (DoF) inertial measurement unit (IMU) delivering inertial sensing performance that provides comparable performance to far heavier, larger, and more costly, fiber optic gyro-based IMUs. This 50 x 50 x 50mm unit operates in extreme temperatures, delivering exceptional low noise performance with class-leading bias instability and excellent angle random walk.
Key Features:
- 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
CRH03
The CRH03 is a single axis gyro offering FOG-comparable performance. It is highly tolerant to external vibration, delivers excellent bias instability and angle random walk, and is available in five rate ranges, including an option of 10 degrees per second, and can be delivered as a packaged unit or an OEM item.
Main Characteristics:
- Operating temperature: -40°C to +85°C
- Bias instability: 0.03° to 0.1°/hr
- Angular random walk: from 0.005°/√hr
- Rate ranges: ±10°s to 400°/s
DMU11 IMU
Supporting this latest generation of products is a family of established sensors and systems including the DMU11 IMU. Proven in many applications, this compact, low-cost 6 DoF IMU is designed for both low and high-volume applications. It offers premium low-noise performance with class-leading bias instability and random walk.
Core Attributes:
- Operating temperature: -40°C to +85°C
- Random Walk: Angular – 0.40°/√hr. Linear – <0.05 m/s√hr
- Bias Instability: <10°/hr, <0.05mg
- Noise: Gyro – 0.1°/s rms. Acc – 1mg rms
Discussions with current and potential customers from among over 4,000 show visitors reportedly highlighted the growing significance that inertial sensing is playing in the geospatial community.
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.”
