IMU440
MEMS INERTIAL MEASUREMENT UNIT
The MEMSIC IMU440 is a high-reliability low power
strapdown inertial system providing accurate measurement of angular rate and linear acceleration in
dynamic environments, with output data also
available in delta theta and delta velocity format.
The IMU440 is offered in standard and high range
sensor configurations to allow the best match for
the user's application.
Features
• 3-Axis Angular Rate and 3-Axis Linear Acceleration Outputs
• Delta Theta and Delta Velocity Outputs
