Epson Starts Shipping New IMUs Optimized for Autonomous Applications

The M-G370 offers FOG class performance while the M-G365 will be the standard for the Epson’s next-generation IMU

Seiko Epson Corporation (TSE: 6724, “Epson,”) has developed and recently commenced shipping samples of two new, high-performance six-axis inertial measurement units (IMU)1, the M-G370 and the M-G365. Both models are scheduled for volume production at the end of 2018.

Epson launched its first IMU in 2011. Since then, Epson IMUs have been used in a multitude of applications, earning an excellent reputation for outstanding performance and quality. Rapidly increasing demand from autonomous precision agriculture machinery, intelligent construction machinery and unmanned vehicle applications has fueled demand for high-accuracy positioning in a compact, cost-effective package. Epson’s new IMUs were developed to offer outstanding quality and productivity with the FOG2-class performance needed to realize practicable autonomous driving and navigation. In addition, the new IMUs maintain backward compatibility with the earlier M-G364 and M-G354, making it easy to upgrade performance.

Product Features

The M-G370 and M-G365

  • Newly developed high-performance sensors that offer higher stability and lower noise in a wide dynamic range.
  • Outstanding dynamic performance (scale factor non-linearity) for high-precision measurement, from static states to high-speed motion.
  • Backward compatibility with the earlier M-G364 and M-G354, sharply reducing customer development costs and evaluation time.
  • Low current consumption (16 mA, compared to 18 mA for the M-G364 and M-G354).

M-G370

  • Epson’s top-of-the-line IMU provides FOG-class performance in a 1-inch package.
  • Ideal for inertial navigation and other applications that require excellent position measurement accuracy, such as autonomous and unmanned applications.
  • A newly-developed gyroscopic sensor3 provides sharply improved in-run bias instability4 (0.8°/hr), angular random walk5, and noise performance.
  • A newly-developed accelerometer provides dramatically improved in-run bias instability performance of 6 uG (compared to 50 uG for the M-G364) and initial bias error of 2 mg (1σ).

M-G365

  • The standard for the next generation, this IMU has a new attitude angle output function and supports a wide variety of applications.
  • An original high-speed DSP6 with an extended Kalman filter7 provides highly accurate real-time attitude angle output (Roll/Pitch/Yaw)8 at low power consumption.
  • Eliminates the need for high-speed calculation of dynamic attitude angle on the system end, thus reducing system load and power consumption.

Application Examples

  • Autonomous driving and unmanned control of precision agriculture and construction machinery.
  • Unmanned equipment such as industrial drones, ground and subsea vehicles.
  • Navigation systems (GNSS9, INS10, high-precision locators).
  • Gimbaled camera and antenna stabilization.
  • Vibration, angle and path measurement of industrial equipment and vehicles.
