Output Data Definition of coremicro IMU:

The data that is output from the uIMU represents three axis of angle change (delta angle) and three axis of velocity change (delta velocity) during the previous 500 usec time period. The angle data is output in counts where each count is equated to units of angle (typically deg/count or radians/count) with a scale factor provided with the unit. The velocity data is output in counts where each count is equated to units of velocity (typically ft/sec/count or m/sec/count) with a scale factor provided with the unit.
The delta velocity data is with respect to the Inertial reference frame, but expressed or resolved into the frame of the uIMU. During angular motions of the uIMU, the delta velocity data will represent an orientation at some time near the middle of the time interval.
The delta angle data represents the amount of angle change during the interval about the uIMU frame with respect tothe Inertial frame. For a single axis example, this is analogous to the angle change output from a shaft encoder if the encoder frame were fixed to the Inertial frame. Cross axis angle change is not measured by the sensitive axis.
The delta angle data is not the same as angular rate, but is very highly correlated to angular rate. Likewise, the delta velocity data is not the same as acceleration data, but is highly correlated to the acceleration.


coremicro IMU USB Adapter

AGNC-2000CMIMU-USB

The coremicro IMU USB Adapter is an option for the user to select as an accessory for coremicro IMU evaluation and testing. It converts IMU’s synchronized serial signal to a standard USB data sequence. Using this data adapter, the user can connect a coremicro IMU to a PC for data acquisition, display, demo or real-time system process testing. A PC-based demo software and driver are provided for basic data transmission and display.
