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 ...
