Introduction
The ER-3MG-01 3-Axis North-Seeking MEMS Gyro has small volume,
light weight, simple structure and good reliability. The biggest
function of the three-axis gyroscope is to “measure the angular
velocity to judge the motion state of the object, so it is also
called a motion sensor”. In other words, this thing can let our
equipment know where we are and where we are going.
Application
Construction machinery dip angle measurement, angle control,
pylon operation monitoring, medical equipment angle control,
satellite antenna star search, bridge, tall building, tower, dam
monitoring and rock and soil monitoring, mining, attitude/heading
reference system, integrated inertial navigation.
