First launched in 2011, Epson’s IMUs have been used in an array of customer applications, from precision agriculture (GNSS2) and industrial drones to camera and antenna platform vibration control and stabilization, earning an excellent reputation for outstanding performance and quality. Epson has a full range of IMUs, from basic models to high-spec models. All are based on a platform that measures about one inch along the sides, the standard form factor for IMUs.
As with the standard and basic models, the high-spec M-G370G allows users to select an accelerometer output range of either ±8G or ±16G and offers 0.05% non-linearity3 of the full-scale range of the gyroscopic sensor. These features enable the new IMU to accurately measure all types of motion, from slow to fast.
By expanding and enhancing its lineup of small, lightweight, low-power, one-inch platform products, Epson is giving customers more options, allowing them to choose a product that has the best functions and performance for their needs and applications.
Epson plans to exhibit the M-G370G at Maintenance and Resilience Tokyo 2023 (organized by the Japan Productivity Association) from July 26-28 at Tokyo Big Sight.
Given the social and technological changes that are underway, Epson believes that the need for precision sensors that can visualize information will only expand going forward. We at Epson will continue to leverage our philosophy of efficient, compact, and precise innovation to provide small, lightweight, low-power sensing systems that offer outstanding precision and stability to significantly contribute to our customers’ products and services.

1 Inertial measurement unit (IMU)An IMU is a device that is used for sensing inertial motion. It is comprised of triaxial angular rate sensors and triaxial accelerometers.
2 A global navigation satellite system (GNSS)A satellite system that is used to pinpoint a geographic location anywhere in the world
3 Non-linearityThe maximum deviation from an approximate straight line of the output versus input of a gyroscopic sensor or accelerometer. It is typically expressed as a percentage of the full scale.
4 Inertial navigation system (INS)
5 Gyroscopic sensor (angular rate sensor)Measures the rotation angle (angular rate) of an object versus a reference axis per unit of time.
6 Bias instabilityThe part of the Allan variance* that represents the horizontal (zero power) characteristic is called bias instability. It correlates with 1/f noise and is one of the important indicators of sensor potential.
7 Angle random walkThe part of the Allan variance with a slope of -1/2 is called the angle random walk. Since there is a correlation with white noise, increasing the average time decreases the value at -1/2 of the average time.
* Allan variance
An indicator of sensor performance, the Allan variance indicates the stability of the static output. The horizontal axis shows the averaging time of data, and the vertical axis shows the distribution of the average value when separated by the average time. It is known that the slopes of the characteristics appearing in the Allan variance are -1, -1/2, 0, 1/2, and 1st power slopes, the Allan variance correlates with the noise density, and the noise density is the frequency. Allan variance is an indicator expressed in time. The smaller the value, the higher the stability and the better the performance.
