METHOD FOR ESTIMATING A TRAJECTORY ORIENTATION FOLLOWED BY A MOVEMENT SENSOR CARRIER, CORRESPONDING DEVICE AND COMPUTER PROGRAM

摘要

This estimation track orientation then carries movable sensor (22) and includes the following steps: the azimuth motion sensor (22) for determining (100) relative to track; Estimate (102), the orientation of motion sensor (22) is relative to fixed coordinate system; The orientation of assessment (104) track determines movable sensor (22) relative to track and estimation orientation motion sensor (22) relative to fixed coordinate system relative to fixed coordinate system by orientation. In addition,It sequentially includes the following steps: the motion sensor (22) of the fault orientation in the beginning and end stage of detection (110) relative to track; It updates (112), the misorientation stage in detected end, the orientation of motion sensor (22), it determines relative to track, it is for example about the misorientation stage of the beginning misorientation stage detected and azimuth motion sensor (22) relative to fixed coordinate system, as estimated detected end in such a way relative to fixed coordinate system by the orientation of the track.
