Problems solved by technology

Although this processing method can insert the emergency task into the original planning plan the fastest, it cannot guarantee that the emergency task can be completed within the corresponding processing time limit, and at the same time, it cannot provide more insertion opportunities for the emergency task
Therefore, the current response to emergency tasks is not satisfactory.

Abstract

The embodiment of the invention provides a multi-star emergent task planning method and device. The method comprises the steps that according to the task completion time limit of an emergent task, a ground station and a visible time window of each remote sensing satellite, the latest observation completion time of each emergent task on each remote sensing satellite, then, according to the latest observation completion time, the usable visible time window for observing the emergent task is screened out, finally, the emergent task is inserted into the usable visible time window where the emergent task can be inserted, and therefore the task completion time limit for the emergent task is applied to an emergent task plan so as to ensure that the emergent task can be completed before the task completion time limit; compared with an existing scheme, the method is more reasonable. In addition, when the emergent task cannot be directly inserted, conflict insertion deletion is designed according to the conflict priority substitution degree, one or more conflict tasks are deleted, the emergent task and conventional task insertion probability is increased, and the benefits of the whole schemeare increased.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of remote sensing monitoring, and more specifically, to a multi-satellite emergency task planning method and device. Background technique [0002] Remote sensing satellites are satellites that use various remote sensors onboard to observe ground targets and obtain high-resolution images. Because remote sensing satellites have the advantages of wide coverage, long duration, and no restrictions on airspace and national boundaries, they play an important role in military investigations and environmental protection. [0003] At present, remote sensing satellite resources are limited, and an optimized observation mission plan must be formulated in order to maximize the use of satellite resources and maximum observation targets, and provide users with more telemetry information. Therefore, multi-satellite mission planning is very important. [0004] During the actual observation process usi...
