Multi-satellite on-orbit observation task planning method based on contract net capable of being reduced

Abstract

The invention discloses a multi-satellite in-orbit observation task planning method based on a contract net capable of being reduced, and the method comprises the steps that: a main satellite screens and determines candidate satellites according to the received task requirements; the main satellite issues task requirements to each candidate satellite; each candidate satellite receives a task requirement and judges a task type, and for a common task, a target function value is calculated, and bidding information is sent to the main satellite; for an emergency task, when a visible time window which meets task requirements and is occupied by other common tasks exists, the other common tasks are set as tasks to be desolvated, a target function value is calculated, and bidding information is sent to the primary satellite; the main satellite selects the candidate satellite with the minimum target function value as a bid-winning satellite according to the received bidding information, and sends a bid-winning notification to the bid-winning satellite; and the bid-winning satellite receives the bid-winning notification, accepts the task, and processes the task to be subjected to reservation solving, so that the multi-satellite task planning is completed.

Description

technical field [0001] The invention relates to the field of satellite mission planning, in particular to a multi-satellite on-orbit observation mission planning method based on a contract network that can be cancelled. Background technique [0002] Earth observation satellites capture ground image information through observation payloads such as visible light and SAR, providing technical support for national defense construction, urban planning and many other fields. With the rapid development of my country's aerospace technology, the types and number of satellites in orbit are increasing rapidly. At the same time, application scenarios such as battlefield information support and emergency disaster observation have put forward new timeliness requirements for satellite observation tasks. Therefore, the mission planning of satellites is required to have the ability to respond quickly. [0003] In the traditional "Sky Star-Ground Network" satellite working mode, mission planni...

Problems solved by technology

In the traditional contract network algorithm, tasks will be released to all satellites. When the number of satellites is large, the system communication pressure will increase.

In addition, the traditional contract network conducts indiscriminate bidding for all tasks, and satellite tasks have different requirements and degrees of urgency, which cannot guarantee the priority of emergency tasks such as natural disaster monitoring
