Description
3DM-GX1® combines three angular rate gyros with three orthogonal DC
accelerometers, three orthogonal magnetometers, multiplexer, 16 bit A/D
converter, and embedded microcontroller, to output its orientation in dynamic
and static environments.
Operating over the full 360 degrees of angular motion on all three axes,
3DM-GX1® provides orientation in matrix, quaternion and Euler formats. The
digital serial output can also provide temperature compensated, calibrated data
from all nine orthogonal sensors at update rates of 350 Hz.
Networks of 3DM-GX1® nodes can be deployed by using the built-in RS-485 network
protocol. Embedded microcontrollers relieve the host system from the burden of
orientation calculations, allowing deployment of dozens of 3DM-GX1® nodes with
no significant decrease in system throughput.
Output modes and software filter parameters are user programmable. Programmed
parameters and calibration data are stored in nonvolatile memory.
How it works
3DM-GX1® utilizes the triaxial gyros to track dynamic orientation and the
triaxial DC accelerometers along with the triaxial magnetometers to track
static orientation. The embedded microprocessor contains a unique programmable
filter algorithm, which blends these static and dynamic responses in real-time.
This provides a fast response in the face of vibration and quick movements,
while eliminating drift. The stabilized output is provided in an easy to use
digital format. Analog output voltages proportional to the Euler angles can be
ordered as an option.
Full temperature compensation is provided for all nine orthogonal sensors to
insure performance over a wide operating temperature range.
