Description
Technical Field
[0001] This invention belongs to the field of unmanned system swarm control and artificial intelligence technology, specifically relating to an autonomous decision-making method and system for unmanned aerial vehicle swarms that integrates BeiDou enhanced services and multi-source perception. Background Technology
[0002] With the development of drone swarm technology, its application in fields such as emergency rescue and environmental monitoring is becoming increasingly widespread. However, in remote areas, oceans, or complex mountainous terrains without terrestrial network coverage, the capabilities of swarm systems face severe challenges: First, positioning accuracy is insufficient; traditional positioning methods such as GPS have meter-level accuracy, which is insufficient to meet the needs of precise collaborative operations. Second, communication link interruptions prevent collaborative decision-making within the swarm and with the rear. Third, the lack of a unified, high-precision spatiotemporal reference for perception and decision-making leads to distorted information fusion and a decline in decision quality.
[0003] The satellite-based augmentation and global short message services provided by the BeiDou-3 global satellite navigation system offer a unique infrastructure for solving the aforementioned problems. However, the current application of BeiDou technology in the field of unmanned aerial vehicles (UAVs) is mostly limited to single positioning or communication functions, failing to deeply integrate it into the intelligent decision-making closed loop of unmanned systems and failing to fully realize its potential as a "spatiotemporal information hub".
[0004] Therefore, there is an urgent need for an innovative solution that can systematically integrate BeiDou's cutting-edge services with advanced artificial intelligence decision-making technology to unlock the advanced autonomous capabilities of drone swarms in extreme environments.

At the same time, the information fusion model is used to process local perception features and wide-area geographic information to generate a global environmental situation tensor with time and space confidence. The global environment situation tensor is input into a pre-trained deep reinforcement learning policy network to obtain the task instruction set; The key instructions in the task instruction set are confirmed through consensus using BeiDou global short message service to obtain the consensus-based task instructions. Each UAV performs collaborative operations based on the consensus-based mission instructions, and integrates the new perception data generated during the execution process with the precise PVT information in real time, and then inputs it back into the information fusion model to complete the autonomous decision-making closed loop.

Each UAV in the UAV cluster receives satellite-based augmentation signals and uses precise point positioning technology to perform real-time calculations on the satellite-based augmentation signals to obtain precise PVT information.
[0021] In this embodiment, each unit in the UAV swarm uses an airborne BeiDou-3 receiver to receive PPP-B2b and / or Galileo HAS satellite-based augmentation signals. Through precise point positioning technology, it calculates and obtains absolute coordinates at the centimeter to decimeter level in real time. This high-precision position, velocity, and time information is used as a unified spatiotemporal reference to provide accurate spatiotemporal labels for all sensing data and subsequent decision-making.

The introduced spatiotemporal reliability compensation term aims to add extra attention scores to data sources with higher positioning accuracy and better signal quality. This design allows the model to prioritize trusted sensing data with higher positioning accuracy and better spatiotemporal quality during fusion, in addition to focusing on the relevance of information content.
