Title:
SATELLITE SIGNAL CAPTURING METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/185893
Kind Code:
A1
Abstract:
Provided in the present application is a satellite signal capturing method. A terminal can determine the propagation time of an RDSS outbound signal from a satellite ground device to a satellite and the propagation time of the RDSS outbound signal from the satellite to the terminal by means of receiving navigation messages (comprising ephemeris parameters, 1PPS pulses, ionospheric parameters, etc.) which are broadcasted by the satellite by means of an RNSS signal. Then, the terminal can determine a phase time shift of a chip during a propagation process of the RDSS outbound signal. The terminal can capture the RDSS outbound signal on the basis of phase time shift of the RDSS outbound signal during the propagation process. In this way, the terminal can quickly capture the RDSS outbound signal.
