Precise Point Positioning with Partial Ambiguity Fixing
Sensors, 2015 Reliable and rapid ambiguity resolution (AR) is the key to fast precise point positioning (PPP). We propose a modified partial ambiguity resolution (PAR) method, in which an elevation and standard deviation criterion are first used to remove the low ...

Precision-Aided Partial Ambiguity Resolution Scheme for GNSS Attitude Determination [PDF]
The International Technical Meeting of the The Institute of Navigation, 2023 The use of carrier phase data play an important role for high-precision Global Navigation Satellite Systems (GNSS) positioning solutions, such as Real-Time Kinematic (RTK). Similarly, precise orientation information can be obtained with multi-antenna setups which exploit carrier phase observables. The availability of high precision navigation solutions

Long Baseline GPS+BDS RTK Positioning with Partial Ambiguity Resolution [PDF]
The International Technical Meeting of the The Institute of Navigation, 2017 Reliable real-time kinematic positioning requires the occurrence of incorrect integer ambiguity estimates to be limited to a maximum tolerable rate. For long baselines this usually implies long convergence times due to the presence of atmospheric delay parameters.

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.

Predicting the Success Rate of Long-baseline GPS+Galileo (Partial) Ambiguity Resolution [PDF]
Journal of Navigation, 2014 This contribution covers precise (cm-level) relative Global Navigation Satellite System (GNSS) positioning for which the baseline length can reach up to a few hundred km. Carrier-phase ambiguity resolution is required to obtain this high positioning accuracy within manageable observation time spans.

On reliable data-driven partial GNSS ambiguity resolution
GPS Solutions, 2014 In high-precision global navigation satellite system applications, it is often not possible to simultaneously meet the requirements for fast and reliable integer ambiguity resolution. For a given reliability constraint in form of a user-defined, tolerable probability of an incorrect ambiguity estimate, resolving a subset of ambiguities instead of the ...

Reliable GPS + BDS RTK positioning with partial ambiguity resolution
GPS Solutions, 2016 Reliable carrier phase positioning requires the occurrence of incorrect integer ambiguity estimates to be limited to a maximum tolerable rate. In various simulation studies, partial ambiguity resolution (PAR) techniques were shown to be beneficial, since it is more likely that a subset of all ambiguities can be reliably resolved rather than the full ...

Partial ambiguity resolution for reliable GNSS positioning — A useful tool?
2016 IEEE Aerospace Conference, 2016 In differential global navigation satellite system positioning applications with short to moderate observation time spans, carrier phase ambiguity resolution is required to obtain precise coordinate estimates. Depending on the length of the baseline, differential atmospheric delays between the two receivers may have to be considered, thus weakening the
