Autonomous Positioning Utilizing Star Sensor and Inclinometer

摘要：

　　An autonomous positioning method is introduced in this study.When the signals of navigation satellites are under disturbance or even the position of the vehicle cannot be covered by navigation satellites,the vehicles position(longitude and latitude)can be obtained accurately through the presented method.Three apparatus are involved in this study,a precise time device,a star sensor,and a dual-axis inclinometer.Data from the three devices are integrated and putted into a measurement model to determine the vehicles position.To determine the rotation matrix between the star sensor measuring reference frame and the inclinometer measuring reference frame,a calibration method based on QUEST is proposed.The night sky experiments show that the autonomous positioning system can achieve high accuracy of 0.0002 degree in longitude and latitude respectively by continuous multiple measurements.
