METHOD FOR GNSS POSITIONING AND ELECTRONIC DEVICE FOR PERFORMING THE SAME

A method for global navigation satellite system (GNSS) positioning and an electronic device performing the same are disclosed. According to an example embodiment, the method includes monitoring whether an error of GNSS positioning occurs, determining whether a first output frequency of a first phase-locked loop (PLL) for demodulating a GNSS signal for GNSS positioning received from a satellite is stable when the error of GNSS positioning is detected, and determining whether the first output frequency of the first PLL is stable when the first output frequency of the first PLL is unstable. A frequency for demodulating the GNSS signal is changed to a second output frequency of the second PLL or a fundamental frequency input to the first PLL and the second PLL. 公开了一种用于全球导航卫星系统(GNSS)定位的方法和执行该方法的电子装置。根据示例实施例，该方法包括：监测是否发生GNSS定位的错误，当检测到GNSS定位的错误时，确定用于解调从卫星接收的用于GNSS定位的GNSS信号的第一锁相环(PLL)的第一输出频率是否稳定，以及当第一PLL的第一输出频率不稳定时，将用于解调GNSS信号的频率改变为第二PLL的第二输出频率或者输入到第一PLL和第二PLL的基本频率。
