Disclosed is a method for global navigation satellite system (GNSS) positioning and an electronic device performing the method. According to an example embodiment, the method includes monitoring whether an error of the GNSS positioning occurs, determining, when the error of the GNSS positioning is detected, whether a first output frequency of a first phase locked loop (PLL) used for demodulating a GNSS signal received from a satellite for the GNSS positioning is stable, and changing, when the first output frequency of the first PLL is unstable, a frequency used for demodulating the GNSS signal to a second output frequency of a second PLL or a basic frequency input to the first PLL and the second PLL.
