Dual-mode location position system

A method of operating a dual mode positioning system having multiple network communication devices for performing WPS (wireless local-area network positioning system) positioning and a satellite GPS (global positioning system) receiver coupled to a switch, wherein one of said multiple network communication devices includes a GPS receiver, said method comprising:

• receiving GPS signals from a number of satellite GPS transmitters by said one of said network communication devices including a CPS receiver;
• performing location positioning to update GPS data by analyzing received GPS signals;
• sending updated GPS position to DSS (Distribution Service System) that has a library of static positions of said multiple network communication devices and dynamic positions of said satellite GPS receiver, wherein said DSS is coupled to said multiple network communication devices for performing said WPS positioning;
• correcting GPS positions of said multiple network communication devices and said satellite GPS receiver;
• associating with said satellite GPS receiver, said multiple network communication devices to perform location positioning to establish and update WPS data;
• sending updated WPS data of said satellite GPS receiver to said DSS;
• and
• transforming updated WPS data to (GPS format and correcting the position of said satellite GPS receiver based on said updated GPS data.

A method of operating a dual mode positioning system having multiple network communication devices for performing WPS (wireless local-area network positioning system) and a satellite GPS (global positioning system) receiver coupled to a switch, wherein one of said multiple network communication devices includes a GPS receiver, said method comprising:

• changing to a GPS mode and receiving OPS signals from a number of satellite GPS transmitters;
• updating GPS data by analyzing said received GPS signals if said satellite GPS transmitter number is sufficient, otherwise checking the valid status or the standard deviations of GPS data and performing location positioning if status is valid or if standard deviations are less than a plurality of thresholds;
• changing to a joint GPS/WPS mode and sending the request for updated joint GPS/WPS position to associated network communication device if said status is not valid or if said standard deviations are higher than said thresholds;
• and
• receiving updated joint GPS/WPS data with said standard deviations from said associated network communication device.
