Method for global navigation satellite system (GNSS) positioning and electronic device performing the same

An electronic device comprising:

• a processor;
• a global navigation satellite system (GNSS) antenna configured to receive a GNSS signal from a satellite to perform GNSS positioning;
• a transceiver comprising a GNSS receiver that demodulates the GNSS signal, a radio frequency (RF) transceiver, a first phase locked loop (PLL) that provides a first output frequency for operating the GNSS receiver, and a second PLL that provides a second output frequency for operating the RF transceiver, and configured to communicate with the processor;
• and
• a fifth-generation (5G) module comprising an antenna for 5G communication and configured to communicate with the RF transceiver,
• wherein the processor is configured to:
• monitor 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 during the 5G communication,
• determine whether the first output frequency of the first PLL used for demodulating the GNSS signal is stable, and
• change, when the first output frequency of the first PLL is unstable, a frequency used for demodulating the GNSS signal to the second output frequency of the second PLL or a basic frequency input to the first PLL and the second PLL.

A method of performing global navigation satellite system (GNSS) positioning in an electronic device having fifth-generation (5G) communication capability, the method comprising:

• determining a current movement path of the electronic device;
• predicting an entry into an area in which the 5G communication is available based on the current movement path and 5G network coverage map data comprising information on the area in which the 5G communication is available;
• and
• changing, when a record that a frequency used for demodulating a GNSS signal is changed is present, the frequency used for demodulating the GNSS signal from a first output frequency of a first phase locked loop (PLL) of the electronic device to a second output frequency of a second PLL of the electronic device before entering the area in which the 5G communication is available.
