Abstract
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.
