Trajectory Reckoning Method Based on BDS Attitude Measuring and Point Positioning
The traditional outdoor integrated positioning and navigation system is normally suffered by the disadvantages of accumulative error and high power consumption. To solve this problem, we propose a new trajectory reckoning method which use the BeiDou system (BDS) to conduct the attitude measuring and point positioning with respect to the target. In concrete terms, the target location is estimated by solving the pseudo-range observation equation, while the attitude angle is obtained from the dual-difference pseudo-range and carrier phase observation equations. Then, the trajectory of the target is constructed based on the estimated location and associated attitude angle. Finally, the extensive experimental results demonstrate the effectiveness of the proposed trajectory reckoning method with the BDS attitude measuring and point positioning.
