Title:
BYPASS NETWORK GUIDANCE METHOD BASED ON SATELLITE PAYLOAD PLATFORM
Document Type and Number:
WIPO Patent Application WO/2021/018121
Kind Code:
A1
Abstract:
Disclosed is a bypass network guidance method based on a satellite payload platform, which can unitize a change in a whole-network satellite ground station distance and the influence of a Doppler frequency shift to realize accurate quasi-synchronization between the clock of the whole network and the clock of a satellite. According to the bypass network guidance method based on a satellite payload platform, in a satellite communication system, a bypass guidance signal is sent on the basis of a satellite payload platform by taking a satellite-borne high-stability clock source as a reference; and the guidance signal is sent to all lower satellite beams to provide the guidance signal to all the satellite stations covered by a satellite.
