Inertial navigation systems are used in a wide range of products such as robots, automobiles and aircraft as well as home electronics and video game consoles. As we are all familiar from the everyday use of GPS navigation devices in automobiles or smart phones, inertial navigational systems continuously calculate the orientation and velocity of a moving object and provide this data to a computer. For a precise calculation of data, test and calibration of the built-in accelerometer sensors is required at various orientations, usually about two rotational axes, during prototype test or in production.
