Abstract: This paper introduced a Synchronous method if group control in real time remote control systems. Starting with the design of the structure of the instruction codes and pseudorandom codes in sequences, an instantaneous synchronous method of the system has been obtained in which the starting phase can float randomly. The main features of this method are simplicity of circuit structure and reduction of tithe for synchronous tracking and synchronous holding existed in all the traditional synchronous methods, thus the controlled objects "respond rapidly and move accurately", and satisfy the requirements for the real time remote control.
