摘要： Methods and apparatus are provided for factorized processing of a first set of GNSS signal data derived from signals having at least three carriers and a second set of GNSS signal data derived from signals having two carriers. A geometry filter process is applied to the first set of GNSS signal data and the second set of GNSS signal data using a geometry carrier-phase combination to obtain an array of ambiguity estimates for the geometry carrier-phase combination and associated statistical information. A first bank of ionosphere filters is applied to the first set of GNSS signal data and a second bank of ionosphere filters is applied to the second set of GNSS signal data, the ionosphere filters using a geometry-free ionosphere carrier-phase combination to obtain an array of ambiguity estimates for the ionosphere carrier-phase combination and associated statistical information. At least one bank of geometry-free and ionosphere-free filters is applied to the first set of GNSS signal data using a geometry-free and ionosphere-free carrier-phase combination to obtain an array of ambiguity estimates for the geometry-free and ionosphere-free carrier-phase combination and associated statistical information. At least one first code filter is applied to the first set of GNSS signal data and at least one second code filter is applied to the second set of GNSS signal data, the code filters using a plurality of geometry-free and ionosphere-free code-carrier combinations to obtain an array of ambiguity estimates for each the code-carrier combinations of the at least one first code filter and the at least one second code filter, and associated statistical information. The resulting arrays are combined to obtain a combined array of ambiguity estimates for all carrier phase observations and associated statistical information.
