A satellite positioning method, a satellite pseudorange calculation apparatus and a satellite pseudorange calculation method thereof are provided. The satellite pseudorange calculation apparatus is used for calculating a pseudorange between a satellite and a satellite positioning receiving device, wherein the pseudorange includes an integer code value and a fractional code value. The satellite pseudorange calculation apparatus comprises a receiver and a processor electrically connected with the receiver. The receiver is configured to receive a code phase from a satellite signal acquisition unit, and the processor is configured to calculate the fractional code value according to the code phase. The receiver is further configured to define an approximation position and calculate the integer code value according to the approximate position and the fractional code value. The satellite positioning method is used for positioning the satellite positioning receiving device.
