Zusammenfassung:	PURPOSE: A synchronization improvement method of a marine telematics Galileo satellite system is provided to solve a plurality of peak problems of AltBOC(alternative binary offset carrier) signals and CBOC(composite BOC) signals. CONSTITUTION: A unit pulse signal S0alt, S2alt, ···,S2k-1alt is defined to indicate an AltBOC(kn, n) signal subcarrier in a half period. A correlation function of the defined unit pulse signal and AltBOC(1.5n, n) signals are indicated as R0alt, R2alt, ···,R2k-1alt and by reuniting a sum total of the correlation functions according to an equation, the correlating function removing a peripheral peak. [Reference numerals] (AA) AltBOC subcarrier; (BB) Pseudo noise code chip time; (CC,DD,EE,FF) Time
