With the development of active optics, control technology and computer, telescope control system (TCS) becomes more
and more complicated. Large telescope control system contains thousands of controlled objects, and large telescopes are
usually built in special location. These are challenge for control system. This paper research advanced control technique
of TCS, presents the topology structure of wireless local area networks control, remote control based on satellites and
wireless portable control and expatiates the real-time design of telescope control units.
