FAQ

FAQ

What is Inertial System Configurations?

Nearly all IMUs fall into one of the two categories outlined below. The difference between the two

catagories is the frame of reference in which the rate-gyroscopes and accelerometers operate. Throughout

this report we will refer to the navigation system’s frame of reference as the body frame and to the frame

of reference in which we are navigating as the global frame, as shown.

What is Sensor Technology and Data Fusion?

Each inertial sensor technology has its specific advantages and drawbacks which have to be considered regarding the foreseen application and desired accuracy. Some sensor technologies come e.g. with a very high stability of sensor performance (e.g. ring laser gyros) while others are for instance very light weight and comparable cheap, but affected by possible aging effects (like MEMS based sensors). Therefore the signal processing on system level (“data fusion”) has to take care for this.

What is Misalignment?

A misalignment between the gyro axes (or accelerometer axes) causes a cross-coupling between the measurement axes. A misalignment of 0.1 mrad inside of the system (e.g. residual calibration mismatch) leads to a roll error of 0.036 degree during one revolution around the yaw axis (if the sys-tem is unaided). The smaller the required misalignment, the higher the requirements for sensor performance and calibration equipment.
