A method of generating the correlation function of a TMBOC(6,1,4/33) signal according to the present invention includes generating a signal delayed based on a phase delay τ with respect to a signal pulse train of a TMBOC(6,1,4/33)-modulated received signal, generating 12 partial correlation functions by performing the autocorrelation operation of the received signal and the delayed signal with respect to a total time T(0≦t≦T) , generating a sub-correlation function by performing an elimination operation of sixth and seventh partial correlation functions, and generating a main correlation function by summing results obtained by performing elimination operations between the remaining 10 partial correlation functions, excluding the sixth and seventh early partial correlation functions from the 12 partial correlation functions, and the sub-correlation function. The elimination operation is an operation satisfying algebraic relations in which |A|+|B|−|A−B|=0 when real numbers A and B are AB≦0 and |A|+|B|−|A−B|>0 when the real numbers A and B are AB>0 .
