Seiko Epson Corporation has expanded its lineup of inertial measurement units¹ (IMU) equipped with high-performance, six degrees of freedom sensors. The new M-G370PDT ("M-G370T" below) is a low-noise premium model that is now in volume production and began shipping in February 2024.

First launched in 2011, Epson's IMUs have been used in an array of customer applications, from precision agriculture (GNSS²), low earth orbit small satellites³ using consumer industrial components, and EO/IR camera gimbals⁴ to antenna platform vibration control and stabilization, earning an excellent reputation for outstanding performance and quality. In recent years, IMU use has expanded into fields such as aerial surveying and low earth orbit satellite video photography, 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-G370T is a one-inch model that combines the best features of two current models, the M-G370PDS and the M-G370PDG, and offers both low noise and high accuracy measurement. It has the same 0.03°/ √h angle random walk⁵ (an important IMU performance indicator for short-term variation in output) as the M-G370PDS ("M-G370S" below) and also has high noise immunity to more accurately detect slight attitude changes that occur in equipment and systems. Also, like the M-G370PDG ("M-G370G" below), the new IMU allows users to select an accelerometer output range of either ±8G or ±16G. It also offers 0.05% non-linearity⁶ on the full-scale range of the gyroscopic sensor.⁷ These features enable the new IMU to accurately measure all types of motion, from slow to fast.

By expanding and enhancing its lineup of 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 particular needs and applications.

Given the social and technological changes that are underway, Epson believes that the need for precision sensors will only expand going forward. We will continue to leverage our philosophy of efficient, compact, and precise innovation to provide small, lightweight, low-power sensing systems that offer outstanding precision, high stability, and low noise to significantly contribute to our customers' products and services.
