Satellite communication ground station, ground receiving system and communication method

Abstract

The invention discloses a satellite communication earth station, a ground reception system and a communication method used for the satellite earth station, and relates to the field of communication. The satellite communication earth station, the ground reception system and the communication method of the invention can avoid the collapse of communication channels, raise the bandwidth utilization rate, and substantially reduce the operation costs of satellite earth stations and the whole satellite communication networks. The satellite communication earth station of the invention comprises a communication subsystem and a communication monitoring subsystem. The communication subsystem comprises an on-duty communication machine and a plurality of auxiliary communication machines. The communication monitoring system comprises a bandwidth monitoring module. The bandwidth monitoring module is used to determine whether a communication data flow exceeds the bandwidth of the on-duty communication machine. The bandwidth monitoring module is also used to switch on the auxiliary communication machines one by one when the communication data flow exceeds the bandwidth of the on-duty communication machine until the total bandwidth of the on-duty communication machine and the auxiliary communication machines which are switched on is not less than the communication data flow.

Description

technical field [0001] The invention relates to the communication field, in particular to a satellite communication ground station, a ground receiving system and a communication method for the satellite ground station. Background technique [0002] Satellite communication is the communication that uses satellites as relays. Due to the advantages of large communication range, high reliability, rapid opening and flexible setting, satellite communication has developed rapidly in recent years. [0003] The satellite communication system generally includes two parts, the communication satellite and the ground station. The communication satellite acts as a relay station in the air, that is, it amplifies the electromagnetic waves sent by the ground station and then sends them back to another ground station; the ground station is the communication between the satellite system and the ground public network. , The interface of the user end, the ground user can also enter and exit the ...

AI Technical Summary

Problems solved by technology

[0004] The bandwidth of satellite communication is limited by the bandwidth of the transponder on the satellite, the bandwidth of the leased channel, and the bandwidth of the ground station. When the traffic suddenly increases, it is easy to cause congestion of the communication channel, resulting in communication failure, but increase the bandwidth design of the ground station It will increase the cost and operation cost of the ground station, and the channel rental fee of the satellite communication network is expensive, but the communication content is the same or there are many repeated parts, and the utilization efficiency is low
