As one of the earth orientation parameters, UT1-UTC characterizes the irregularities of the earth rotation speed, and plays an important role in many space exploration activities such as space autonomoμs navigation, deep space probe orbit determination. Yet China has not established the relatively stable independent guarantee ability of UT1-UTC, it is of great reference signifi-cance to carry out UT1-UTC determination simulation at the early stage of system planning and construction. In this paper, the Mon-te Carlo simulation analysis of UT1-UTC solution is carried out by μsing VieSked++ software, and the measured data is utilized to verify the simulation conclμsions. Firstly, the IVS conventional observation mode is simulated, and subsequently about 100 times of IVS conventional observation data are used for comparison and verification. The results show that the actual solution accuracy is about 1.4 times of the repeatability factor. Secondly, the UT1-UTC intensive observation simulation is carried out for the single base-line of the Chinese deep space network, which is located in the northern and southern hemispheres, respectively. The simulation re-sults show that the UT1-UTC solution accuracy of the JM-KS baseline and the NM-AG baseline of the deep space network is expect-ed to be about 18 μs and 22.4 μs, respectively. Furthermore, the real observation data by JM-KS baseline of China deep space net-work are used for resolving UT1-UTC to verify the simulation result. Finally, on the basis of deep space network station resources,the simulation of multi-station and multi-baseline UT1-UTC monitoring capability is carried out. The results of this paper effectively evaluate the ability of UT1-UTC monitoring based on single baseline of China deep space network, and provide reference for subse-quent system construction and UT1-UTC solution ability evaluation.
