Marine autonomy depends on dependable motion data, including when GNSS signals are unavailable or a platform is operating in a high-vibration environment. AMCORIS distributes Epson MEMS inertial measurement units across Europe for use in navigation, stabilization, and georeferencing systems.
The IMUs measure three-axis angular velocity and linear acceleration within compact, low-power packages. Their proprietary quartz crystal sensing technology supports low drift and stable angular rate detection, while integrated correction functions compensate for temperature, alignment, sensitivity, and offset.
For USVs, AUVs, and ROVs, the units can support navigation and autonomous operation as well as roll and pitch stabilization. IP67-rated models are available for challenging operational environments. AMCORIS also supports developers and system integrators with pre-qualified evaluation kits, application know-how, and integration assistance.
M-G366PDG: Balancing SWaP-C
EPSON M-G366PDG
Where size, weight, power, and cost must be considered together, the M-G366PDG provides Epson’s Best SWaP-C option.
The IMU measures 24 x 24 x 10 mm and combines a ±450°/s gyro range with selectable ±8g or ±16g accelerometer ranges. It provides 1.2°/h bias instability and angular random walk of 0.08°/√h.
SPI and UART interfaces are available for system integration.
M-G370PDT: Low Angular Random Walk
The M-G370PDT combines a compact 24 x 24 x 10 mm footprint with angular random walk of 0.03°/√h, the lowest figure among the models listed here.
It provides 0.8°/h bias instability, a ±200°/s gyro range, and selectable ±8g or ±16g accelerometer ranges. SPI and UART interfaces are supported.
The Wider IMU Range
The broader Epson portfolio available through AMCORIS includes entry-level, high-performance, compact, and larger-format units.
EPSON M-G370PDT
Options vary by package dimensions, gyro range, accelerometer range, bias instability, angular random walk, and interface. Available interfaces across the listed models include SPI, UART, RS-422, and J1939, with CANopen or RS-422 specified for the M-G552 Series.
This range allows developers and system integrators to compare models according to the motion-sensing and integration requirements of a particular marine platform.
