摘要：
In this paper, the basic theory and mathematical model of two-way satellite-ground time transfer are presented. The error model is deduced and error budgets are analyzed and concluded that the accuracy approaches 0.9 ns. Furthermore, software was developed and actual two-way satellite-ground observations from COMPASS validation testing were processed. The results indicate that the accuracy of satellite-ground time transfer in COMPASS validation phase is 1.0 ns.
