GNSS phase deviation product generation method, terminal and computer storage medium

The invention relates to a GNSS phase deviation product generation method, a terminal and a computer storage medium, and the method comprises the steps: obtaining the original observation data of a satellite, and the original observation data of the satellite comprises carrier phase observation values and pseudo-range observation values of different frequencies; generating a plurality of double-frequency phase deviation products according to the carrier phase observation values and the pseudo-range observation values of the different frequencies; and generating a plurality of single-frequency phase deviation products according to the plurality of double-frequency phase deviation products. According to the GNSS phase deviation product generation method, the terminal and the computer storage medium provided by the invention, multiple double-frequency phase deviation products are fused through unifying the reference frequency to generate a multi-frequency phase deviation product, so that the generation process o
