Performance of ambiguity-resolved detector for GNSS mixed-integer model. [PDF]
GPS SolutAbstract Teunissen (J Geod 98(83):1–16, 2024) proposed the ambiguity-resolved (AR) detection theory for GNSS mixed-integer model validation. In this contribution, we study the performance of the AR detector through analysis and simulation experiments and compare it with the ambiguity-float (AF) and ambiguity-known (AK) detectors.

OFDM-Based Carrier Phase Localization With Integer Ambiguity Resolution
IEEE AccessThis study introduces a two-stage Time Difference of Arrival (TDoA) localization method using OFDM signals with carrier-phase measurements. Unlike conventional methods, our approach uniquely resolves integer ambiguities in carrier-phase signals by ...

RELIABILITY OF THE GPS CARRIER-PHASE FIX SOLUTION UNDER HARSH CONDITION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Once the unknown integer ambiguity values are resolved, the GPS carrier phase observation will be transformed into a millimeter-level precision measurement. However, GPS observation are prone to a variety of errors, making it a biased measurement.

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.

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.

Using dispersion-induced group delay to solve the integer ambiguity problem: a theoretical analysis [PDF]
Journal of the European Optical Society-Rapid Publications, 2015 This paper describes a novel approach for solving the integer ambiguity problem when the adjacent pulse repetition interval length (APRIL) from a femtosecond optical frequency comb (FOFC) is used as a length scale.
