Receiving apparatus, receiving method, computer program and a mobile terminal

To provide a receiving device which is capable of reducing average power and peak power by holding pseudo synchronization of a satellite signal during a sleep period. Provided is a receiving device including a receiving unit for receiving a signal from a satellite, a frequency conversion unit for converting a frequency of the received signal into a predetermined intermediate frequency, a synchronization acquisition unit for carrying out synchronization acquisition and for detecting a carrier frequency, and a synchronization holding unit for assigning and setting, per satellite, a phase of the spread code and the carrier frequency to each of a plurality of channels independently provided in a corresponding manner to a plurality of the satellites to synchronously hold the spread code and a carrier and also for demodulating a message included in the intermediate frequency. The synchronization holding unit includes a spreading code generation unit for generating a spreading code synchronized with the spread code, and in a sleep period in which a positioning operation is not carried out, the synchronization holding unit causes only the spreading code generation unit to operate and a counter that the synchronization holding unit refers to also operates.
