摘要
An electronic device receives satellite signals from positioning information satellites and acquires positioning information and time information. A stored data table comprises a first block of data having a first array of time difference data and a second block of data having a second array of time difference data that is different than the first array of time difference data. A stored memory address table stores the memory address of each of the first and second blocks of data, at least one the blocks of data being stored a plurality of times in the memory address table. The data block corresponding to the acquired positioning information is identified, the memory address corresponding to that data block is read, the data block data indicated by the memory address is acquired, and the time difference data for the segment corresponding to the positioning information is acquired from the data block.
