摘要:A position determination system and apparatus for utilizing a network ofcellular base stations to determine position of a mobile station includes taking a pluralityof statistically independent data measurements of the pilot signals from the basestations. Each of the data measurements includes an earliest time of arrival, providingmultiple independent measurements for each of the pilot signals. For each cellular basestation, a representative measurement is calculated responsive to the independentmeasurements, which is used to determine position of the mobile station using an AFLTalgorithm and/or in conjunction with a GPS algorithm. In some embodiments, the datameasurements for each pilot signal further include an RMSE estimate and time ofmeasurement for each time of arrival, and an energy measurement for all resolvablepaths. If the mobile station comprises a cell phone, a cell search list and a GPS search listmay be provided by a cell base station.
