Abstract

The invention provides a remote sensing satellite relay receiving resource application method and system. The method comprises the following steps: determining a relay receiving resource demand window, receiving a relay satellite idle window, and calculating a visible window between a remote sensing satellite and a relay satellite; taking an intersection of the relay receiving resource demand window, the relay satellite idle window and the visible window to form a to-be-selected window; for the satellites which are not pre-allocated yet and have the highest priority, allocating to-be-selectedwindows to the satellites in each demand time period in sequence; according to a previous to-be-selected window allocation result, performing conflict resolution on the unallocated to-be-selected windows, and updating the states of the to-be-selected windows; and repeatedly executing the operations of to-be-selected window allocation and conflict resolution until the to-be-selected window allocation of all remote sensing satellites is completed. The remote sensing satellite relay receiving resource application method and system provided by the invention have the advantages of simple judgment logic and low time complexity.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellites, in particular to a method and system for applying for relay receiving resources of remote sensing satellites. Background technique [0002] Remote sensing satellite and relay satellite resources are independently managed and controlled by different systems, and the remote sensing satellite management and control system schedules and uses relay receiving resources based on the "apply first and use later" mode. The relay satellite can be visible to multiple remote sensing satellites at the same time, and the remote sensing satellite can be visible to multiple relay satellites at the same time, but the relay satellite can only provide services for one remote sensing satellite at the same time, and the remote sensing satellite can only use one relay satellite. How to automatically resolve relay resource application conflicts and efficiently allocate idle receiving resources of mult...
