Satellite positioning method, satellite pesudorange calculation apparatus and satellite pesudorange calculation method

A satellite pesudorange calculation method for calculating a pesudorange between a satellite and a satellite positioning receiving device, the pesudorange comprising an integer code value and a decimal code value, the satellite pesudorange calculation method comprising the following steps of:

• (a) enabling a receiver of the satellite positioning receiving device to receive a code phase from a satellite signal acquisition unit of the satellite positioning receiving device;
• (b) enabling a processor, which is electrically connected to the receiver, of the satellite positioning receiving device to calculate the decimal code value according to the code phase;
• (c) enabling the processor to define an approximation position;
• and
• (d) enabling the processor to calculate the integer code value according to the approximation position and the decimal code value.
