Abstract: A slice set for a specific period of time is acquired from a storage area of a memory which is a ring buffer while changing the read position, and the signal strength total value of each slice set is calculated. The signal strengths of the slices included in the maximum strength slice set and the signal strengths of the slices preceding or subsequent to the maximum strength slice set are calculated, and the final signal read position is determined based on a read offset of the maximum strength slice. A GPS satellite signal is acquired and tracked based on the slice read from the determined signal read position, and a specific positioning process is performed.
