To
the Attention of coremicro IMU buyers
Due to the specialized
technical support inquiries from the users of our coremicro IMU,
AGNC only sells the coremicro IMU as part of the Universal
Navigation and Control Unit and the
Universal
Navigation and Control Unit with Differential GPS
which already have the coremicro IMU embedded in them. We determined
that this is the most efficient way to help our coremicro IMU
users.
“The world’s
smallest(1999)” IMU with microelectromechanical
systems (MEMS): AGNC-2000CMIMU coremicro IMU (Inertial
Measurement Unit)
It
provides angle increments, velocity increments, a time base (sync)
in three axes and is capable of withstanding high vibration and
accelerations. Applications include land navigation, automobiles,
personal navigators, robotics and marine vehicles, etc.
The AGNC-2000CMIMU
coremicro IMU is a fully self-contained motion sensing unit ideal
for various communication, instrumentation, guidance, navigation,
and control applications.
Beyond
the State of the Art MEMS IMU:
Compared with a conventional
IMU the coremicro IMU utilizes feedforward open loop signal
processing to obtain highly accurate measurements by means of
signal digitization and temperature control and compensation
of angular misalignments and non linearities. An angular rate
producer is provided for measuring vehicle angular rate, wherein
high performance dither drive signal generation and angular
sensing signal extracting means are provided for hands-on vibrating
type angular rate detecting units, to obtain highly accurate
angular rate signals. The angular rate producer includes a vibrating
type angular rate detecting unit for detecting angular rate
via Coriolis Effect; an interfacing circuitry for converting
angular motion-induced signals from the vibrating type angular
rate detecting unit into angular rate signals and converting
inertial element dither motion signals from the vibrating type
angular rate detecting unit into processible inertial element
dither motion signals; and a digital processing system for locking
the high-quality factor frequency and amplitude of the vibrating
inertial elements in the vibrating type angular rate detecting
unit by means of providing an electronic energy including dither
drive signal for the vibrating type angular rate detecting unit
using the processible inertial element dither motion signals.
The AGNC coremicro
IMU uses advanced MEMS angle rate and accelerometers combined
with precision interface circuitry and digital conversion to achieve
accurate angle increment and velocity increment sensing.
The product's typical applications
include:
The coremicro IMU provides a
simple all digital serial interface for ease of connection to
additional system components. The inertial data provided by
this unit establishes a frame of reference for the equipment
to which it is affixed. The frame is defined by the sensitive
axis of each of the six sensors and provides all three dimensions
of motion sensing.
