Abstract

The invention provides an allocation method and device for bandwidth resources in a spatial information network and relates to the technical field of satellite communication. The method comprises the following steps: at least one information-source satellite connected to a relay satellite is determined; an idle transmission bandwidth is detected in the at least one information-source satellite, wherein the idle transmission bandwidth is the bandwidth resource used for data transmission to a target information-source satellite in advance and the target information-source satellite is one information-source satellite of the at least one information-source satellite, and the communication channel between the target information-source satellite and the relay satellite is an idle channel; when the idle transmission bandwidth is detected, the at least one information-source satellite connected to the relay satellite at the current time is updated, and the bandwidth resources are reallocated to the at least one updated information-source satellite; and target data is transmitted to a ground service station through the reallocated bandwidth resources. The technical problem in the prior art that the transmission bandwidth resources of the relay satellite can not be allocated dynamically is solved.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method and device for configuring bandwidth resources in a space information network. Background technique [0002] The current deployment of earth observation satellites, especially environmental and resource satellites, is mainly the deployment of low-orbit satellites, whose orbital altitude ranges from 300 to 2,000 kilometers. The main advantage of deploying in this altitude range is the ability to obtain higher resolution Earth's surface or atmospheric data. However, this deployment method also has many disadvantages. On the one hand, due to the limited deployment range of ground stations in my country, stations cannot be deployed globally, and the data obtained by satellites cannot be transmitted back to the ground in time; The period is long. Taking satellites with an orbital altitude of 300 to 400 kilometers as an example, the transit time is generally i...
