<P>PROBLEM TO BE SOLVED: To provide global navigation satellite systems which can determine a position location for a mobile station based on satellite signals transmitted from two or more satellite systems. <P>SOLUTION: Each of first and second navigation satellite systems (NSS) is suitable for operating, respectively, by first and second specifications. Each of a plurality of first and second SVs is adapted to be identified, respectively, by a plurality of first and second unique corresponding identifiers (ID). A processor is suitable for receiving and identifying a plurality of first communication signals to be transmitted from the plurality of first SVs according to the plurality of first unique corresponding IDs, and is adapted to receive and identify the plurality of second communication signals to be transmitted from the plurality of second SVs according to the plurality of second unique corresponding IDs. The processor is adapted to determine position location information according to reception and identification of the plurality of first communication signals and the plurality of second communication signals. <P>COPYRIGHT: (C)2012,JPO&INPIT |
