Navigation system using a spreading code based on a pseudo-random noise sequence

One embodiment of the present invention provides a receiver for use in a navigation system including a plurality of transmitters. Each transmitter transmits a location confirmation signal including the pseudo-random noise (PRN) sequence corresponding to the transmitter. The receiver includes a code module for providing a plurality of PRN sequence corresponding to a plurality of transmitters, and a correlator for obtaining the correlation of the PRN sequence and the input signal supplied from the code module. Multiple PRN sequences based on one Sidelnikov / Lempel / Cohn / Eastman ( SLCE) generating sequence Satisfied, [Number 2] Represents a binary XOR sum of each element, T
