Improved GNSS integer ambiguity resolution method based on the column oriented Cholesky decomposition [PDF]
Scientific Reports, 2023 Because the traditional Cholesky decomposition algorithm still has some problems such as computational complexity and scattered structure among matrices when solving the GNSS ambiguity, it is the key problem to further improve the computational ...

Influence of Pseudorange Biases on Single Epoch GNSS Integer Ambiguity Resolution
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

Flight-Test Evaluation of Integer Ambiguity Resolution Enabled PPP
Journal of Surveying Engineering, 2021 The technology of integer ambiguity resolution-enabled precise-point-positioning (also referred to as PPP-AR) has been proven capable of providing comparable accuracy, efficiency, and productivity to long-baseline real-time kinematic positioning (RTK) during the last decade.
