Rc Logger Orientation & G-Force Module
This product is intended for connecting it
with the RC Logger HD, RC Logger HD2, RC Logger PRO or RC Logger LC
(not included) to provide orientation and force information for a model
helicopter, model car or model airplane. The product is powered by the
RC Logger's battery. By using Magnetometer, Gyroscope and
Accelerometer with 3D orientation and calculation algorithm to
determine pitch angle, yaw angle, roll angle, direction, acceleration,
and angular velocity during flight. With the recorded orientation
information, realistic flight path can be simulated with the use of RC
Logger Viewer Software.
MEMS Sensor technology
The advanced MEMS (Micro Electro-Mechanical
System) sensor technology plays an essential role in the Orientation
& G-Force module. Small mechanical system in micron size can be
added into an IC chip such that a very small sensor or actuator can be
fabricated by MEMS and IC technology, allowing motion sensing and
control to take place in miniature scale, fitting perfectly for the ever
popular RC model applications.
3-axis Magnetometer
A three axis magnetometer is used in the
Orientation & G-Force module to come up with a 9 DoF Inertial
measurement unit (IMU). The calculation algorithm is adopted with
modified Kalman Filter to handle the high level of noise generated in
the RC helicopter environment, such as vibration, magnetic field by
motor, and effect of gravity with continuous orientation change. A more
accurately predicted output is generated by the sensor data collected
over time, providing a better orientation and motion information.
3-axis Accelerometer
The 3-axis Accelerometer is used to measure
the acceleration and orientation of the RC model. Acceleration signals
can be integrated to velocity and displacement information as an
inertial measurement. It can detect motion, vibration and shock, as well
as measure gravity to determine orientation of the object such as tilt
and inclination.
3-axis Gyroscope
The 3-axis Gyroscope is used to measure the
angular velocity of the RC model. When the RC model rotates along an
axis (e.g. roll, pitch, or yaw), rate of rotation can be determined by
the gyroscope. The gyro electronics can resolve very small capacitance
change, resulting in a very high sensitivity. The gyroscope can thus
measure angular rate with high accuracy and sensitivity.
