PROBLEM TO BE SOLVED: To provide a satellite signal receiving apparatus capable of detecting and capturing weak signals by securing longer correlation time.SOLUTION: A satellite signal receiving apparatus includes: a down converter 20 which converts signals from a navigation satellite into a digital signal; a correlator 34 which performs correlation processing between a digital signal and a pseudo noise code; and a signal detection part 36 in which a correlation processing result obtained by the correlator 34 is divided, the Fourier transformation processing is performed with respect to each divided data, a Fourier transformation processing result is multiplied by a rotation factor to make phases match with each other in each frequency, and the Fourier transformation processing results are added together. |
