Abstract :
This paper describes the first implementation of Delta-DOR (Delta-Differential One-Way Ranging) in CE´3 navigation within China DSN(Deep Space Network). Tracking data during CE´3 cruise to the moon is analyzed. Compared with high accurate orbit ephemeris, time delay error in the delta-DOR measurement is less than 1ns, which corresponds to an angular accuracy of about 90nrad or 37m uncertainty on the probe position at 380000km. Delta-DOR tracking has played an important role in CE´3 navigation.
