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.
