%X The method to rebuild space-borne pseudo-range measurements from real-time position data is discussed first in this paper. And then, the accuracy of dynamic orbit determination using rebuilt pseudo-range measurements and precise GPS ephemeris is analyzed in detail. Data from GRACE-A satellite from March 1 to 14 in 2008 is processed for this purpose. Research results show that the accuracy of real-time single point positioning using C/A code pseudo-range measurements and GPS broadcast ephemeris is about 15m, and the accuracy of dynamic orbit determination in post-processing mode is about 2m. It is demonstrated that dynamic orbit determination using rebuilt pseudo-range measurements in post-processing mode can not only significantly improve the position accuracy of real-time navigation solutions, but also provide consecutive satellite orbits.
