如果采用双通道调制解调器，则可实现多站同时时间传递。但对于来自双通道调制解调器的多站数据的处理仍然采用经典算法，没有发挥同时性的优势。此外，从测量的结果是不是一个封闭的集合和系统是不均匀的。为了改进它，已经开发了一种算法。新算法的计算结果更加精确和准确。确定了卫星与地面站之间的精确伪距。
The time transfer among multi-station at the same time can be reached if the two-channel modems are employed. But the classical algorithm is still used for processing the multi-station data from the two-channel modems, so that the advantage of simultaneity is not used. Furthermore, the result from measurements is not a closed set and the system is not uniform. In order to improve it,an algorithm has been developed. The result from the new algorithm is more precise and accurate. And the precise pseudoranges between satellite and stations are determined.
