摘　　要：针对分布式伪卫星组网定位系统中各伪卫星时钟难以同步或精度不高的问题,本文提出一种新型的分布式伪卫星钟差解算方法以提升伪卫星时钟同步精度。通过设计合理的时钟分配方案,采用载波相位观测方程建立星间钟差模型,可以解算出组网内各个伪卫星间的钟差。根据实验采集的数据和仿真结果验证,该分布式伪卫星钟差解算方法可行。In view of the infrequent synchronization or the inaccuracy generated by each independent pseudolite clock in the distributed pseudolite network positioning system,a novel solution to the distributed pseudolite clock offset is proposed to improve the accuracy of pseudolite clock synchronization.With a rational clock allocation scheme and a carrier phase observation equation utilized to establish an inter-satellite clock offset model,the clock difference between each pseudo-satellite in the network can be solved.Experimental data and simulation results reveal the approach to solving the distributed pseudo satellite clock offset.
