For this purpose, the paper discusses the development process of electric performance compensation methods for radio telescopes, presents the characteristics of large antennas with the application of the active surface adjustment, summarizes the key active adjustment technologies, compares typical large antennas using active adjustment for the antenna main reflectors, and eventually discusses the structure design program and research proposal for active surface compensation of the QiTai Telescope (QTT) antenna in Xinjiang, China.
Therefore, it is suggested that the QTT antenna actuators should adopt a stepping motor and the light screw design, with a precision sensor design scheme, which should be supplemented by deicing and low-temperature resistance sealing measures to ensure robust operation under the conditions of the Qitai observatory environment.

The project covers the city of Fukang and counties of Hutubi and Qitai.
We look forward to working with our counterparts to improve urban infrastructure and services delivery supported by sound planning in Fukang, Hutubi, and Qitai, to help people, including rural migrants, take full advantage of growing opportunities presented by the economic corridor.
Specifically, the Xinjiang Changji Integrated Urban-Rural Infrastructure Demonstration Project will help local governments better manage the water supply and solid waste in Qitai. It will also fund the planting of trees in Fukang, which will help preserve soil, reduce flooding, and form ecological protection shelterbelts.
Radio Telescope will have a fully steerable receiver located near Qitai
in the Xinjiang Uyghur Autonomous Region (200 km northeast of Urumqi).

The intended project outcome is increased urban and rural residents accessibility to quality urban infrastructure services in Fukang, Hutubi, and Qitai. The indicative proposed project outputs are (i) improved urban services infrastructure; (ii) constructed or rehabilitated urban-rural road infrastructure; (iii) installed technical and vocational skills training facilities; and (iv) developed project management capacity of government agencies and community groups.
Project Outcome: Urban and rural residents accessibility to quality urban infrastructure services in Fukang, Hutubi, and Qitai increased
