Epson launches high specification M-G370PDG to expand its one inch platform IMU product line

精工爱普生公司(TSE: 6724，“爱普生”)开发了M-G370PDG(“M-G370G”)，扩展了其惯性测量单元1 (IMU)阵容，该IMU配备了高性能的六自由度传感器。M-G370G将于2023年7月投入量产。

Epson's IMU was first launched in 2011 and has been used in a range of customer applications, from precision agriculture (GNSS2) and industrial drones to vibration control and stability for cameras and antenna platforms, earning a good reputation for excellent performance and quality. Epson has a full range of IMUs, from basic models to high-end models. All of these are based on a platform approximately one inch along the edge, which is the standard shape factor of IMU.

Like standard and basic models, the high spec M-G370G allows users to choose between an accelerometer output range of ± 8G or ± 16G, and provides 0.05% of the full range of nonlinear gyroscope sensors. 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, and low-power one inch platform products, Epson provides customers with more choices, allowing them to choose products with the best functionality and performance according to their needs and applications.

Epson plans to showcase the M-G370G at the Tokyo Big Sight event "Maintenance and Resilience Tokyo 2023" (hosted by the Japan Productivity Association) from July 26th to 28th.

Given the ongoing social and technological changes, Epson believes that the demand for precision sensors capable of visualizing information will only continue to expand. Epson will continue to leverage our innovative concepts of efficiency, compactness, and precision to provide small, light, and low-power sensing systems, providing excellent accuracy and stability, and making significant contributions to customer products and services.

5. General specifications

1 Inertial Measurement Unit (IMU)

IMU is a device used to sense inertial motion. It consists of a three-axis angular rate sensor and a three-axis acceleration sensor.

2 Global Satellite Navigation Systems (GNSS)

A satellite system used to determine the geographical location of any place in the world

3 nonlinearity

The maximum deviation of the output of a gyroscope sensor or accelerometer from the approximate straight line of the input. It is usually expressed as a percentage of the full scale.

4 Inertial Navigation Systems (INS)

5 gyroscope sensors (angular rate sensors)

Measure the rotation angle (angular velocity) of an object relative to the reference axis within a unit time.

6 Unstable biases

The portion of Allan variance * that represents the horizontal (zero power) characteristic is called bias instability. It is related to 1/f noise and is one of the important indicators of sensor potential.

Random walk at 7 angles

The part of Allan variance with a slope of -1/2 is called angle random walk. Due to the correlation with white noise, increasing the average time will result in a decrease in the value at -1/2 of the average time.

Allen variance

As an indicator of sensor performance, Allan variance represents the stability of static output. The horizontal axis represents the average time of the data, and the vertical axis represents the distribution of the average value separated by the average time. Given that the characteristic slopes appearing in Allan variance are -1, -1/2, 0, 1/2, and 1st power slopes, Allan variance is correlated with noise density, which is frequency. Allan variance is an indicator expressed in time. The smaller the value, the higher the stability and performance.
