In three times of the antarctic surveying research expeditions, a complete and accurate surveying system has been established in the Chinese Great Wall Station area. The surveying system includes geodetic coordinate system, elevation system and gravity reference system. In this paper, the surveying methods and the mathematical models for establishing these systems are discussed, and the accuracy of results is analysed.展开更多

With a total investment of 859 million RMB and a five-year construction period, the project was supervised by the Ministry of Education of China and the Hubei Provincial People’s Government, and jointly established by the Chinese Academy of Sciences (CAS) and the Wuhan Municipal People’s Government. The application was initiated in 2010, approved in 2015, and construction began in 2018. Huazhong University of Science and Technology, China (HUST) serves as the legal entity, in collaboration with the CAS Innovation Academy for Precision Measurement Science and Technology, China University of Geosciences (Wuhan), and Sun Yat-sen University, China (Luo et al., 2016).展开更多
