High-precision 6-axis inertial measurement unit 'DMU41'
A high-precision MEMS inertial measurement device that replaces the IMU equipped with a fiber optic gyro. Compared to the old model, it achieves compact size, lightweight, and low power consumption.
The DMU41 is a high-precision MEMS inertial measurement device that replaces the IMU equipped with a fiber optic gyro. Suitable for applications requiring high accuracy, the DMU41 achieves a compact, lightweight, and low power consumption design compared to the previous model, the DMU30. The previous model (DMU30) has a proven track record in a wide range of applications, including ultra-small satellites, and this product can also be used for the same applications. 【Features】 ■ Improved output accuracy and stability ■ Compact (50mm x 50mm x 50mm) and lightweight (200g) ■ Low power consumption of 1.5W (depending on usage conditions) ■ Various interface options available RS422/RS485 * Evaluation samples are available for loan. * For more details, please download the PDF or feel free to contact us.

Announcement of Participation in the "GPS/GNSS Symposium 2026"
Silicon Sensing Systems will exhibit at the "GPS/GNSS Symposium 2026" to be held at Tokyo University of Marine Science and Technology (Koshigaya Campus) from November 25 (Wednesday) to 27 (Friday), 2026. At this exhibition, we will propose the possibilities of high-precision position and attitude measurement through the integration of GPS/GNSS and inertial sensors. At our booth, we will introduce our product lineup, including the high-precision MEMS-IMU "DMU11," which has been in high demand in the fields of drones and autonomous mobility, as well as the chip-type gyro sensor "CRM series," which is compact, lightweight, and suitable for board mounting. Additionally, we will showcase high-reliability sensors with a proven track record in applications such as satellites and space exploration vehicles (e.g., the MMX project), as well as a live demonstration of our flagship IMU "DMU41." If you have challenges related to autonomous navigation (dead reckoning) in environments where GNSS signals are blocked or interrupted, or issues concerning high-precision attitude control and stabilization of moving bodies, please feel free to stop by our booth. We look forward to welcoming you.
