【摘要】 针对全球导航卫星系统运算量急剧增加的问题,提出一种新的BDS/GLONASS双系统快速选星算法。该算法以最小GDOP值为基础,针对多系统的特点制定选星策略,并对算法进行实验验证。实验结果表明,该算法在保证定位精度基础上有效减少了定位解算的运算量。更多还原

【Abstract】 With the development of global navigation satellites is gradually increased. Satellite selection is then proposed in order to achieve a balance between computation and positioning accuracy. This paper presents a fast satellite selection algorithm by using BSS/GLONASS double system. The algorithm is based on the minimum GDOP value,the satellite selection is determined based on the characteristics of multi-system,and the algorithm is validated. The experimental results show that the algorithm can reduce calculation cost under the guarantee of positioning accuracy.更多还原
