Abstract:Based on the introduction of the TCAR (three carrier ambiguity resolution) model, we analyze factors affecting the TCAR algorithm in the long baseline ambiguity resolution. The TCAR algorithm cannot get the correct ambiguity resolution, so a new method based on triple-frequency geometry-free ionosphere-free combinations is advanced to resolve the long baseline quick ambiguity. Finally, Beidou data are used to validate the new algorithm, showing that the TCAR algorithm can resolvethe short baseline ambiguity, and that the new method can resolve long baseline quick ambiguity.
