EEA Announces New Inertial Measurement Units

July 31, 2013

The quartz MEMS-based M-G352 and M-G362 are tailored for demanding unmanned and industrial applications requiring extremely high sensitivity and accuracy.

SAN JOSE, CA /BUSINESS WIRE/ -- Epson Electronics America Inc. (EEA) has developed two new products for its inertial measurement unit (IMU) lineup. The new products, the M-G352 and M-G362, will be demonstrated for the first-time publicly at AUVSI's Unmanned Systems 2013, the "world's largest international exposition of unmanned systems" to be held from August 12 to 15 in Washington, DC, USA.

The M-G352 IMU incorporates a wider gyroscope and accelerometer dynamic range, servicing applications with higher dynamics and greater vibration and shock. Offering a fully calibrated and temperature-compensated measurement range of ±450 °/s for the gyroscopic sensors and ±6 g for the accelerometers, the M-G352 is suitable for industrial and unmanned applications, where high stability is required despite challenging environmental conditions, such as unmanned vehicle guidance, navigation, and control.

The M-G362 IMU achieves 3 °/hr gyro bias instability, approaching the performance of fiber optic gyro and ring laser gyro IMUs at a much smaller size and cost. Offering a fully calibrated and temperature-compensated measurement range of ±150 °/s for the gyroscopic sensors and ±3 g for the accelerometers, the M-G362 is suitable for industrial and unmanned applications, where very high stability is required for extended periods of time, such as high-accuracy gimbaled camera and antenna system stabilization.

The new models are equipped with additional new features, including a higher output data rate (2,000 sps, max.), an external trigger input, and counter reset function, making it easy to synchronize measurements with other sensors or with a GPS module in a user's system.

Released just over two years ago, Epson's current IMU, the M-G350, established a new benchmark for accuracy, stability, and power consumption in a small, lightweight package, primarily serving the commercial and industrial markets in applications such as vibration monitoring and motion tracking. Together, the new M-G352 and M-G362 IMUs extend the reach of Epson's IMU product line, offering customers a variety of solutions tailored to their specific applications.

"The M-G352 and M-G362 IMUs were designed specifically for customers with applications requiring extremely high sensitivity and accuracy," says Bob Porooshani, General Manager for Epson Electronics America. "These new IMUs offer high bias stability and low angle random walk, making them particularly attractive to the antenna pointing and gimbaled camera stabilization industries, plus newly added advanced software features like external trigger synchronization allow customers to easily integrate external aiding sources like GPS and magnetometers."
