Problems solved by technology

[0003] At present, the remote sensing constellations mainly have the following deficiencies: ① The remote sensing constellations do not form a unified whole, and each is the master, lacking joint design and collaboration; ② Ground image processing and information extraction and distribution take a long time, and the timeliness of information utilization is poor. Isolation, poor information coordination ability between constellations; ③Requires ground planning and imaging, lacks independent perception and independent planning capabilities; ④Complicated control mode, not directly designed for user use

Embodiment Construction

[0029] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings of the description.

[0030] The present invention proposes a blockchain-based constellation for long-term requirements such as dynamic change monitoring services, autonomous perception and dynamic planning services, collaboration requirements such as the completion of regional coverage by constellation collaboration, and one-time requirements such as single remote sensing image acquisition services. Consensus method for collaborative operation and control planning.

[0031] The core of the block chain in the present invention is the planning chain, and the record chain includes the demand chain.

[0032] like figure 1 As shown, a blockchain-based consensus method for constellation collaborative operation and control planning, the specific steps include:

[0033] (1) Receive user requirements and perform user verification.

[0034] (2) The node that fir...

Abstract

The invention discloses a block chain-based satellite group cooperative operation control planning consensus method, which is characterized in that spacecraft nodes realize planning consensus based onuniform distribution, and the consensus efficiency is improved by adopting a mode of broadcasting while selecting a candidate scheme, so that a plurality of satellites can be prevented from planningthe same demand to the greatest extent, the concurrency is reduced, and the efficiency is improved. The method supports quick insertion of high-priority tasks and dynamic adjustment of low-priority planning, and adopts the mode of selecting the optimal candidate scheme while broadcasting, so that the storm of broadcast data is effectively reduced, and the consensus efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of remote sensing satellites, and relates to a blockchain-based constellation collaborative operation control planning consensus method, which is used to efficiently form a planning consensus in the blockchain-based constellation collaborative operation and control process. Background technique [0002] Remote sensing satellite data acquisition and imaging capabilities are no longer the main bottleneck, but providing users with more valuable products and more convenient services requires a systematic solution. For example, users need to provide real-time information after multi-satellite images are quickly covered and processed across the country , and keep track of developments in a timely manner. Therefore, the coordinated operation of the constellation as a whole can improve user experience and provide users with overall situational awareness and comprehensive and timely news. [0003] At present, the re...
