Abstract
With the rapid development of Global Navigation Satellite System (GNSS) Precise Point Positioning (PPP) ambiguity resolution, high-quality Multi-GNSS fractional cycle biases products are urgently needed. In this contribution, the ambiguity resolution in Multi-GNSS is deduced in detail based on the observation and precise products provided by multi-GNSS Experiment (MGEX). Meanwhile, a Multi-GNSS wide-lane FCB product estimation method is proposed. Then the wide-lane FCB products of GPS, Galileo and BDS are generated by observations in 2017, DOY24 to 2017, DOY30. It is found that, the wide-lane FCB products of GPS, Galileo and BDS have a good stability after on-board multipath correction. Finally, the validity of FCB products is verified by the wide-lane residual distribution of GPS, Galileo and BDS, in which the correctness of the proposed method is also proved.
