Influence of Pseudorange Biases on Single Epoch GNSS Integer Ambiguity Resolution [PDF]
IEEE 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.

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

Integer‐ambiguity resolution in astronomy and geodesy [PDF]
Astronomische Nachrichten, 2014 AbstractRecent theoretical developments in astronomical aperture synthesis have revealed the existence of integer‐ambiguity prob‐lems. Those problems, which appear in the self‐calibration procedures of radio imaging, have been shown to be similar to the nearest‐lattice point (NLP) problems encountered in high‐precision geodetic positioning and in ...

Sequential Ambiguity Resolution Method for Poorly-Observed GNSS Data
Remote Sensing, 2021 Integer ambiguity resolution is required to obtain precise coordinates for the global navigation satellite system (GNSS). Poorly observed data cause unfixed integer ambiguity and reduce the coordinate accuracy.
