Installation Options of the Module
Free Installation
(Default Mode)
UM220-INS series modules integrate a three-axis gyroscope and a three-axis
accelerometer, with a built-in self-calibration algorithm, which supports the free
installation of the module with respect to any installation angle of the vehicle coordinate
system, such as, the completely horizontal installation, inclined installation at a certain
angle, and flip installation.
Fixed Installation
According to the installation Angle definition, the accurate installation Angle is
manually configured into the module. This installation method takes a short
calibration time.
When configuring the installation angle manually, the maximum angle
error is limited to ± 5 degrees.
