METHOD FOR DETERMINING A HEADING IN THE DIRECTION OF TRUE NORTH USING AN INERTIAL MEASUREMENT UNIT

摘要

What it is the present invention relates to the direction for determining real north, which includes three gyrometers using inertia sensing module, " measurement axis and three accelerometer measures axis; described method includes following steps:, according to northern mode is sought, obtains the calorific value of the first calorific value using from the inertia sensing module; Use the calorific value from the inertia sensing module according to the second calorific value of gyro compass pattern acquiring; Determine that the geographical north direction that heads the ball into the goal uses the beginning fringe value and big broken rice value.
