A Fast Satellite Selection Algorithm for GPS/BD Integrated Navigation System
To realize fast satellite selection for GPS/BD integrated navigation system,a selection algorithm based on the geometry layout is presented.According to the geometry layout feature of the optimal satellite selection result,the visible satellites are divided into different groups by their azimuth and elevation,and then cost function is used for selecting satellites in each group.Compared with the original optimum satellite selection algorithm,the fast satellite selection algorithm need less computation.The emulation result shows that it works well and can keep the Geometric Dilution of Precision (GDOP) within 2.5.It can satisfy the requirements to precision and real-time performance in the aerospace field.
