Improvement of Communication Condition from Lunar Rover to Deep Space Tracking Station in Antarctic Great-Wall Station

If a deep space tracking station is founded in Earth's Antarctic area,communication conditions will be greatly improved attributing to its broader vision.This paper assumes the deep space station is established in Chinese Antarctica Great-Wall station,and simulates the communication accessibility between the lunar rover and the Great-Wall tracking station.Through the comparison with the domestic tracking station's communication condition,the results show that:① The influence of communication condition by topography between the lunar rover in lunar south pole and Great-Wall tracking station is less than that between the lunar rover in lunar south pole and the domestic tracking stations.② The longitude is about 180° from the Chinese Antarctic Great-Wall station to the domestic tracking station.Integrated with all of the tracking stations,including Chinese Antarctic Great-Wall station and domestic tracking stations,the impact of the stations away from the Moon due to the Earth's rotation can be reduced and the tracking time can be lengthened.The simulation and analysis of communication accessibility for choosing Antarctic Great-Wall station as deep space tracking station,can provide a suggestion for the feasibility of construction of the next deep space tracking stations.
