PRN(PSEUDO RANDOM NOISE) CODE ASSIGNMENT SYSTEM OF PSEUDO SATELLITE AND METHOD THEREOF, ESPECIALLY PREVENTING TWO PSEUDO SATELLITES FROM SELECTING SAME PRN CODE

摘要

PURPOSE: A PRN(Pseudo Random Noise) code assignment system of a pseudo satellite and a method thereof are provided to prevent the lacking of PRN codes to be assigned to the pseudo satellite when a number of pseudo satellites are installed in a wide area. CONSTITUTION: The PRN code assignment system is constituted with a control center(100) and a number of pseudo satellites(210,220,230,240,250). The control center stores information of controllable pseudo satellites and assignable PRN codes per time zone internally, and manages a PRN code of a corresponding pseudo satellite using the information. The control center determines a PRN code to be assigned to the pseudo satellites after generating a PRN code management list, and performs wire/wireless communication with the controllable pseudo satellites in order to assign the PRN code to the pseudo satellites. PRN#12 is assigned to the pseudo satellite(210), and PRN#34 is assigned to the pseudo satellite(220), and PRN#19 is assigned to the pseudo satellite(230), and PRN#32 is assigned to the pseudo satellite(240), and PRN#22 is assigned to the pseudo satellite(250). The pseudo satellites(230,240) performs wireless communication with the control center.
