1. A method of performing global navigation satellite system (GNSS) positioning while fifth-generation (5G) communication is performed in an electronic device, the method comprising:
monitoring whether an error of the GNSS positioning occurs based on determining that a current position of the electronic device determined through GNSS positioning after starting 5G communication changes greater than a position change threshold or the current position is lost;
determining, when the error of the GNSS positioning is detected, whether a first output frequency of a first phase locked loop (PLL) of the electronic device 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 of the electronic device, or a basic frequency input to the first PLL and the second PLL.
