Abstract Ambiguity Resolution (AR) is a key technique in GNSS precise positioning. In case of weak models (i.e., low precision of data), however, the success rate of AR may be low, which may consequently introduce large errors to the baseline solution in cases of wrong fixing.

Partial search for multi-carrier GNSS ambiguity resolution
SPIE Proceedings, 2009GNSS carrier phase integer ambiguity resolution is the key for higher precision positioning and navigation. Due to more ambiguities with the multiple frequencies per system, the successful resolution of all ambiguities may not always be possible. However, a subset of the ambiguities can still be possible.

Precision-Driven Partial Ambiguity Resolution Technique for Short to Medium Baseline Positioning
2021 IEEE Aerospace Conference (50100), 2021GNSS carrier phase observations are fundamental for safety-critical applications where the requirements of accuracy and availability are stringent. Upon the deployment of new GNSS constellation and frequencies, the large number of observations can lead to a decreased probability of successfully mapping the real-valued carrier phase ambiguities to ...

Bootstrapping Added Partial Search Strategy for GNSS Integer Ambiguity Resolution
Advanced Materials Research, 2014Integer least square estimator is known to be optimal in GNSS ambiguity resolution. But it relays on a search in the whole ambiguity space which decreases the computational efficiency. A partial search strategy is proposed in this contribution. The new search is limited in an ambiguity space subset defined by the bootstrapping solution; the search-and ...

On reliable data-driven partial GNSS ambiguity resolution
GPS Solutions, 2014In 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, 2016Reliable 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 Preferences and Ambiguity Resolution in Contextual Defeasible Logic
2011Domains, such as Ambient Intelligence and Social Networks, are characterized by some common features including distribution of the available knowledge, entities with different backgrounds, viewpoints and operational environments, and imperfect knowledge.
