Epson Develops the Ideal IMU for Attitude and Vibration Control

PublishTime： 2021-11-04 Article Source：EPSON

Seiko EPSON Corporation ("Epson," TSE: 6724) has developed and is now shipping samples of the M-G370PDS0, a new inertial measurement unit (IMU)¹ equipped with a high-performance six-axis sensor. Volume production of the new product is scheduled for the spring of 2022.

Epson's IMUs, first launched in 2011, have been used in an array of customer applications, earning an excellent reputation for outstanding performance and quality. In recent years, IMU use has expanded into fields such as surveying and aerial and underwater video photography by unmanned systems, creating a growing need for more accurate position and attitude control. Accordingly, demand is rising for IMUs that offer greater precision, which is crucial in attitude control, and especially noise performance. The M-G370PDS0 has an angle random walk² (short-term variation in output) of 0.03 ° / √h, which is half that of its predecessor, and can more accurately detect very slight changes in the attitude of equipment and systems, since they do not get lost in sensor noise. The small size, light weight, and low power consumption of this IMU will help customers make their own products smaller and lighter.

The new IMU maintains compatibility with earlier products (the M-G370/365/364/354), making performance upgrades easy.

Product features

·  Equipped with a low-noise, high-performance sensor that maintains the high stability of Epson's previous IMUs
    Angle random walk of 0.03 °/√h
    Noise density: 2.5 (°/h)/√Hz

· Outstanding dynamic performance (scale factor non-linearity) for high-precision measurement, from static states to high-speed motion

· Maintains compatibility with earlier IMUs (the M-G370/365/364/354), sharply reducing customer development costs and evaluation time

· Low current consumption: 16 mA

Product applications

· Unmanned vehicles (industrial drones, terrestrial vehicles, sea probes, etc.)

· Vibration damping for cameras, antennas, etc.

· Vibration, angle, trajectory measurement of industrial equipment, etc.

· Navigation systems (GNSS³, INS⁴, high-precision locators), etc.
