M-G370 and M-G365: Epson launches two new FOG level high-performance six axis inertial measurement units (IMUs)

M-G370 has FOG (Fiber Optic Gyroscope) level performance, while M-G365 will become the standard for Epson's new generation IMU. It is reported that these two models are planned to achieve mass production by the end of 2018.

As early as 2011, Epson released its * * IMU, which can accurately detect inertial motion information ranging from small tilts to large-scale movements. Since then, Epson IMU has been widely used in aerospace and industrial products, and has won high praise for its outstanding quality and performance.

With the rapid development of autonomous precision agricultural machinery, intelligent construction machinery, and drone applications, the demand for small, cost-effective, and high-precision positioning devices is increasing day by day. Epson's M-G370 and M-G365, with their excellent performance, provide FOG level performance for autonomous driving and navigation.

In addition, M-G370 and M-G365 maintain backward compatibility with earlier models M-G364 and M-G354, allowing for easy performance upgrades.

For M-G370 with FOG level performance, it is widely used in inertial navigation and fields that require high position measurement accuracy, such as autonomous driving and unmanned driving, due to its high precision and stable testing performance.

The M-G370 is also equipped with a gyroscope sensor developed by * * *, greatly improving zero bias stability (0.8 °/hour), angular random walk, and noise performance. And the developed accelerometer greatly improves the zero bias stability (reaching 6uG, while the zero bias stability of M-G364 is 50uG), with an initial zero bias error of 2 mg (1 σ).

The new generation IMU standard M-G365 has simple installation, new attitude angle output function, and supports various applications. The high-speed DSP with extended Kalman filter can provide high-precision real-time attitude angle output (roll angle/pitch angle/yaw angle) with low power consumption. It can be widely used in vehicles, ships, and other industrial products and systems to measure data and control motion, and the system no longer requires high-speed calculation of dynamic attitude angle, thereby reducing system load and power consumption.

It is worth mentioning that both the new M-G370 and M-G365 use high-performance sensors, which have superior characteristics such as better stability, lower noise, and wider dynamic range. And with excellent dynamic performance (non-linear scaling factor), it is very suitable for high-precision measurements from static to high-speed motion.

At the same time, the backward compatibility of M-G370 and M-G365 greatly reduces user development costs and evaluation time, with a lower current consumption of 16mA (compared to 18mA for M-G364 and M-G354).

Application areas:

●Autonomous driving and unmanned control of precision agriculture and construction machinery.

●Unmanned equipment, such as industrial drones, ground vehicles, and underwater devices.

●Navigation system (GNSS * 9, INS * 10, high-precision locator).

● PTZ camera and antenna stabilization system.

●Measurement of vibration, angle, and path of industrial equipment and vehicles.
