At ION GNSS+ 2025, held from 8–12 September in Baltimore, MD, Silicon Sensing will showcase its latest generation of rugged MEMS-based inertial sensors.
The new silicon MEMS technology retains the compact size, low weight, and power efficiency typical of MEMS-based sensors, while delivering significant improvements in bias instability and angle random walk, offering inertial performance comparable to larger, heavier, and more costly fiber optic gyroscope (FOG) systems.
These advancements support accurate and reliable inertial measurements in applications where traditional systems are limited by size, power availability, or environmental conditions, such as ultra-compact platforms, power-constrained systems, and long-duration operations in demanding environments.
Products on display at ION GNSS+ include:
Inertial Measurement Units (IMUs)
DMU41: Tactical-grade, 9-DoF IMU delivering disruptive performance with a power consumption of 1.8W, bias instability of 0.1°/hr and 0.015mg, and random walk figures of 0.02°/√hr angular and 0.05m/s/√hr linear, operating from -40°C to +85°C.
DMU11: Lightweight, low-cost 6-DoF MEMS IMU with angular random walk of 0.40°/√hr, linear random walk under 0.05m/s/√hr, and bias instability below 10°/hr and 0.05mg, operating within a -40°C to +85°C range.
Accelerometers
Gemini®: Surface-mounted dual-axis accelerometer family with five dynamic range options (±0.85g to ±96g), velocity random walk of 0.07m/s/√hr, and compact dimensions starting at 10.4 x 6.0 x 2.2mm, operating from -40°C to +125°C.
CMS300: Combines a MEMS gyro and dual-axis accelerometer in a 10.4 x 6 x 2.2mm package, with angle random walk of 0.40°/√hr, velocity random walk under 0.05m/s/√hr, and bias instability of 10°/hr for the gyro and under 0.05mg for the accelerometer, rated for -40°C to +125°C operation.
Compact Gyroscopes
CRH03: Compact, rugged stand-alone gyro offering bias instability between 0.03° and 0.1°/hr, and angular random walk from 0.005°/√hr, with reliable performance across a -40°C to +85°C temperature range.
PinPoint®: Ultra-compact gyro measuring just 6.3 x 2.7 x 5.5mm, with bias instability between 12°/hr and 80°/hr and angular random walk ranging from 0.2° to 0.8°/√hr, suited for applications operating between -40°C and +85°C.
ION GNSS+ is one of the largest global conferences focused on GNSS technology, products, and services. The 2025 event will gather experts from around the world in positioning, navigation, and timing to present research, highlight new technologies, address current policies, showcase products, and share insights across the industry.
