A heterogeneous multi-platform earth observation system composed of space-based satellites,nearby space-based airships,and space-based drones can complete more complex earth observation tasks.However,the heterogeneous platform earth observation system not only improves the earth observation capability,but also puts forward higher requirements on the dispatching and operation control technology of each platform in the system.Therefore,it is necessary to conduct research on multi-platform and multi-task planning technology,improve the traditional single observation platform and the task planning algorithm of the same type of observation platform,and design heterogeneous multi-platform and multi-task assignment algorithms,which can realize satellites,airships,and unmanned aerial vehicles.The high-efficiency scheduling of the composed heterogeneous multi-platform realizes the distribution and execution of complex earth observation tasks,and provides technical support for obtaining higher mission revenues more efficiently and at a lower cost.Aiming at the multi-task scheduling and planning problems of heterogeneous multi-platform earth observation systems composed of satellites,airships,and UAVs,this paper studies multi-platform multi-task planning technology and simulation demonstration methods,focusing on solving the problem of heterogeneous multi-platform task allocation.,Isomorphic multi-platform task planning problem,multi-platform multi-task planning system simulation demonstration problem,the specific work is as follows:In view of the basic problems of multi-platform and multi-task planning,research and analyze the dynamic characteristics of space-based satellites,adjacent space-based airships,and space-based drones,summarize and sort simplified dynamic models of satellites,airships,and drones,and analyze the platforms And the spatial geometry and visibility of ground targets.Aiming at the task allocation problem of heterogeneous multi-platform earth observation system composed of space-based satellites,adjacent space-based airships,and space-based drones,a heterogeneous multi-platform multi-task allocation algorithm based on contract network is designed to realize multiple tasks in satellites.,Airships,and drones.Aiming at the task planning problems in the three types of platforms(space-based satellites,adjacent space-based airships,and space-based UAVs)a homogeneous multi-platform multi-task planning algorithm based on the contract network is designed for satellites,airships,and UAV platforms.The algorithm can realize the planning of multiple tasks on multiple platforms of the same type.Design simulation demonstration software for multi-platform multi-task planning system,use simulation method to realize multi-platform multi-task planning and execution process demonstration,and design heterogeneous multi-platform multi-task assignment algorithm and homogeneous multi-platform multi-task planning Algorithms are verified and evaluated.Through the research of basic models,allocation algorithms,planning algorithms,and simulation demonstration methods,it can support the earth observation system composed of space-based satellites,nearby space-based airships,and space-based unmanned aerial vehicles to complete complex and massive earth observation tasks and improve observations.The efficiency of resource management and control has great engineering practical application value.
