Product Description

Use and application
The IMUF99, Inertial Measurement Unit, combines an acceleration sensor and a gyroscope
into a single device and links the two sensor elements to increase overall performance of the
system and open up new possibilities. This device is optimized to provide gyroscopic-stabilized
inclination and acceleration data as well as rotation rate data.
Heart of the IMU is the adaptive sensor fusion algorithm. It is developed and implemented for
inclination measurement with extreme effective compensation of external acceleration distur-
bance.
Triaxial acceleration sensor and triaxial gyroscope outputs are used as input of the fusion sys-
tem. The adaptive sensor fusion algorithm is designed to compensate the measurement errors
by combining accelerometer and gyroscope data adaptively to the current situation.
The following figures show the orientation and assignment of the axis for which the sensor can
be used depending on the parameterization of the angle output system.
