Abstract
The 110 m radio telescope (QTT), which is proposed to be built in Xinjiang Qitai, will be in the list of world-leading large scale scientific facilities, becoming the worlds largest fully steerable radio telescope. QTT will play an important role in the field of fundamental science, such as gravitational wave detection, black holes, star formation and galaxy origin, and also be applied to deep space explorations, for example, Lunar Exploration Program and Exploration of Mars and Venus. The QTT design has considered various requirements for science goals, and its key technologies include: large-scale antenna structure design, antenna active surface, large inertia mechanism precision servo control technology, broad band feed, low-noise receiver, multi-beam technology, etc. The breakthrough and application of the key technologies will promote the development of engineering technology, including electronic information, precision machining and automatic control, etc. Through international cooperation, the QTT systems will base on self-dependent innovation and adopt related cutting-edge technologies to fulfill its construction.
