摘要：A method and system for precise position determination of general InternetProtocol (IP) network-connected devices. A method enables use of remote intelligencelocated at strategic network points to distribute relevant assistance data to IP deviceswith embedded receivers. Assistance is tailored to provide physical timing, frequency andreal time signal status data using general broad band communication protocols. Relevantassistance data enables several complementary forms of signal processing gain critical toacquire and measure weakened or distorted in-building Global Navigation SatelliteServices (GNSS) signals and to ultimately extract corresponding pseudo-range timecomponents. A method to assemble sets of GNSS measurements that are observed overlong periods of time while using standard satellite navigation methods, and once
compiled, convert using standard methods each pseudo-range into usable path distancesused to calculate a precise geographic position to a known degree of accuracy.
