1. A computer-implemented method, comprising:

  • performing sequential scanning in multiple directions for global positioning system (GPS) signals via an antenna of an electronic device, the scanning in each of the multiple directions being performed for a time interval;

    analyzing the GPS signals obtained from scans in the multiple directions to determine a number of acquired GPS satellites that provided the GPS signals, the GPS signals indicating code phases of the acquired GPS satellites;

    computing a location of the electronic device based on the code phases of the acquired GPS satellites in response to determining that the number of acquired GPS satellites meets a threshold number; and

    increasing the threshold number in response to a number of directions scanned increasing.
