An inertial unit includes many parameters, such as: position, speed, acceleration and so on. Now estimate the acceleration and angular velocity may seem simple, because an accelerometer can provide a measure of acceleration and a gyroscope can provide a measure of angular velocity. Nevertheless, we will see below that this apparent ease of hiding the very real difficulties. The aim of this paper is not to recreate an complex inertial unit, but try to estimate the inclination angle and the angular velocity of an object by using some math filters, This problem we will not only tap away the complexity of the implementation of an inertial, but more importantly to use a math filter to make the prediction information and data fusion multi -sensors.
