Zusammenfassung:The invention discloses a navigation satellite signal capturing module, a chip and a satellite navigation receiver, which are characterized in that satellite digital signal fragments with set groups are read in sequence from an offset m; a corresponding code phase coherent accumulation unit performs coherent accumulation on each group of satellite digital signal segments and the corresponding spreading code segments to obtain a plurality of coherent accumulated values of the (m + 1) th code phase until a plurality of coherent accumulated values of each code phase are obtained; sequentially arranging the coherent accumulated values belonging to the same code phase to form a coherent accumulated value group, obtaining coherent accumulated value groups of which the number is the same as that of the code phases, and forming a coherent accumulated value large group by all the coherent accumulated value groups; fourier transform is carried out on the coherent accumulated value large group to obtain a transform valu
