AIDING INERTIAL NAVIGATION SYSTEM USING A CAMERA TYPE SUN SENSOR AND METHOD THERE OF

摘要

An attitude correction device and a method of an INS(Inertial Navigation System) using a camera type sun sensor are provided to correct attitude and an error of the sensor by analyzing an LOS(Line-Of-Sight) vector generated from the camera type sun sensor through an image of the moving sun and an output value of the INS. An attitude correction device of an INS(100) using a camera type sun sensor(200) is composed of the camera type sun sensor for measuring the sun with a camera(201) in order to measure the attitude of an airplane; a signal processing unit(300) for receiving attitude and position value from the INS and LOS vector information of the camera type sun sensor and synchronizing the received data; and a data collecting and processing unit(400) for correcting an error by post-processing the information transmitted from the signal processing unit. The data collecting and processing unit calculates an estimated error value from the values of the INS and the sun sensor by using a Kalman filter algorism.
