| Abstract: | The △DOR navigation system based on the VLBI theory can improve the measurement resolution by increasing the distance of the baseline and is recommended strongly in the deep space navigation field. The principle of the △DOR for deep space navigation is introduced and the current research status is reviewed in this article. Several key techniques of the △DOR system are analyzed and the development trend of them is proposed. Finally, this paper indicates some problems that need to be studied furthermore in the field. |
