Integer ambiguity resolution in precise point positioning: method comparison [PDF]

open access: yesJournal of Geodesy, 2010
Integer ambiguity resolution at a single receiver can be implemented by applying improved satellite products where the fractional-cycle biases (FCBs) have been separated from the integer ambiguities in a network solution. One method to achieve these products is to estimate the FCBs by averaging the fractional parts of the float ambiguity estimates, and

Influence of Pseudorange Biases on Single Epoch GNSS Integer Ambiguity Resolution

open access: yesIEEE Access, 2020
Model strength and biases are two main factors for GNSS integer ambiguity resolution. Due to the nonideal GNSS signal, the receiver's observations will be biased.
