摘要

A tightly combined GPS/BDS carrier differential positioning method is provided. The method comprises: using a GPS as a reference system to construct a GPS intra-system double-difference ionosphere-free combination model and a GPS/BDS inter-system double-difference ionosphere-free combination model; selecting a BDS reference satellite to re-parameterize an ambiguity of a GPS/BDS inter-system double-difference ionosphere-free combination and perform parameter decorrelation, estimating an ionosphere-free combination carrier differential inter-system bias in real time, and performing reference conversion on the ionosphere-free carrier inter-system bias to realize a continuous estimability of the ionosphere-free carrier differential inter-system bias in necessary; and finally, using ambiguity-fixed base carrier observations to form the ionosphere-free combination and performing tightly combined positioning on the inter-system double-difference ionosphere-free combination based on the estimated ionosphere-free carrier difference inter-system bias.
