Silicon Sensing will unveil its latest inertial measurement technology at the 2021 AUVSI Xponential trade show in Atlanta. The new products include the DMU41 silicon MEMS (micro electro-mechanical systems) inertial measurement unit (IMU), and the compact standalone single-axis CRH03 gyro.
Measuring just 50x50x50mm and weighing less than 200g, the DMU41 has a 54% lower volume and is 42% lighter than its predecessor, the DMU30, and consumes 50% less power. The new IMU has been designed to compete in performance with much heavier, larger and more costly, fibre optic gyro-based units. The reduced SWaP (size, weight and power) footprint makes it ideal for ultra-precise motion sensing applications for UAVs (unmanned aerial vehicles) and robotic platforms.
The new CRH03 is a high-performance/low-noise, single axis gyroscope that consumes 30% less power than its predecessor (the CRH02) and incorporates new developments in both MEMS and electronics, including new drive electronics and improvements to the sensor head. The unit is highly tolerant to external vibration, delivers excellent bias instability and angle random walk and is available in five rate ranges, including a new option of 10 degrees per second.
All Silicon Sensing products are based on the company’s own unique resonating ring gyroscope technology, and their IMUs also incorporate state-of-the-art accelerometers. All deliver excellent angle random walk, bias instability and low noise performance combined with high shock survivability.
Steve Capers, General Manager of Silicon Sensing, commented: “These new, non-ITAR products offer critical new choices for the fast-growing unmanned sector, where platforms are ever more compact, offer better and more sustained performance and are increasingly rugged, thus able to operate in more severe conditions.”
