A method of determining a signal receiving angle of a GPS(Global Positioning System) signal is provided to determine an optimal GPS signal by adjusting an elevation angle as well as an azimuth angle of a GPS receiver, thereby increasing signal reception efficiency. A coordinate system is set in the basis of a fixed point of a GPS terminal antenna and the moving speed of a GPS terminal is measured(S110). Measurement conditions such as a measuring period and a measuring frequency are determined(S120). The elevation angle of the GPS terminal antenna is adjusted by a predetermined value and elevation angle information of a GPS satellite is obtained(S130). An optimum elevation angle is extracted(S140). The azimuth angle of the GPS terminal antenna is changed by a predetermined value according to the measuring period and the measuring number, such that azimuth angle information of the GPS satellite is obtained(S150). The optimum azimuth angle is extracted(S160). The optimum azimuth and elevation angles for the GPS terminal antenna are determined(S170).
