Abstract: A satellite signal processing method and a satellite positioning apparatus are disclosed, and relate to the field of communication technologies, to improve system performance and user experience when an RNSS is integrated with an RDSS. The satellite positioning apparatus includes: an RNSS radio frequency channel, configured to receive an RNSS received signal; an RNSS baseband processor, coupled to the RNSS radio frequency channel, and configured to perform position, velocity, and time PVT computation on the RNSS received signal to obtain PVT information; an RDSS baseband processor, configured to determine a carrier frequency of an RDSS received signal based on a carrier frequency offset value, where the carrier frequency offset value is generated based on the PVT information; and an RDSS radio frequency channel, coupled to the RDSS baseband processor, and configured to receive the RDSS received signal based on the carrier frequency of the RDSS received signal.
