Abstract

The invention provides a remote sensing satellite data transmission resource scheduling method and device based on bidirectional degree of freedom. The method comprises the following steps: determining an observation time interval of a remote sensing satellite, and calculating a receiving time period of each data transmission resource to the remote sensing satellite; calculating a receiving degreeof freedom corresponding to each observation task based on satellite observation station forecasting; selecting the observation task with the minimum receiving degree of freedom for analysis, and calculating the service degree of freedom of each data transmission resource for receiving the observation task; allocating the data transmission resource with the minimum service freedom degree to the selected observation task; deleting the observation tasks to which the data transmission resources have been allocated, and deleting the allocated data transmission resources; and repeating the processuntil all observation tasks are allocated with data transmission resources. The satellite data transmission resource scheduling method and device based on the two-way degree of freedom provided by the invention have the characteristics of simple judgment logic and low time complexity in allusion to conflict resolution of data transmission resource use by different remote sensing satellites.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellite data transmission resource preallocation, in particular to a remote sensing satellite data transmission resource scheduling method and device based on two-way degrees of freedom. Background technique [0002] Remote sensing satellites rely on data transmission resources to transmit remote sensing data to the ground. Remote sensing satellites can comprehensively schedule and use multiple data transmission resources for remote sensing data return, and digital transmission resources can receive remote sensing data returned by different remote sensing satellites in time-sharing. However, one data transmission resource can only provide data return service for one remote sensing satellite at the same time. How to automatically resolve data transmission resource conflicts and scientifically and efficiently provide multiple data transmission resources to multiple remote sensing satellite...
