Relay satellite single-address antenna dynamic scheduling method for temporary task arrival

Abstract

The invention belongs to the satellite scheduling field and relates to a relay satellite single-address antenna dynamic scheduling method for temporary task arrival. The method comprises the followingsteps: (1) according to the temporary task application information to be processed, matching the visible time window and the antenna available time window; if there are available time period resources, scheduling the temporary task; otherwise, proceeding to the next step; (2) analyzing the scheduled tasks that conflict with the temporary task requirements, and generating t set of tasks to be adjusted at the current layer; (3) trying to adjust the tasks to be adjusted, and if the scheduling is successful, putting an end to the scheduling process; otherwise proceeding to the next step; 4) deleting the resources occupied by the tasks to be adjusted in the current layer, and after scheduling the original temporary tasks, treating the tasks to be adjusted in the current layer as new temporarytasks respectively, so as to realize the expansion operation of the adjustment tree; if the conflicts are resolved within the set adjustment times, determining that the original temporary tasks are scheduled successfully, and outputting the adjusted scheduling scheme; otherwise, outputting the initial scheduling scheme.

Description

technical field [0001] The invention belongs to the field of satellite scheduling, and in particular relates to a dynamic scheduling method for a relay satellite single-site antenna aiming at the arrival of temporary tasks. Background technique [0002] Tracking and Data Relay Satellite (TDRS), referred to as relay satellite, mainly provides data relay, continuous tracking and orbit measurement and control services for medium and low orbit spacecraft. Since its establishment, the relay satellite system has played an irreplaceable role in supporting information-based operations, national defense scientific research experiments, and civil applications. With the continuous expansion of the scope of application, the number of tasks faced by the relay satellite system has increased year by year, and the difficulty of application and scheduling has gradually increased. How to realize the flexible management and efficient utilization of relay satellite resources has become the key...

Problems solved by technology

For such cases, the relevant management agencies of relay satellites are allowed to make adjustments to the generated periodic scheduling plan to meet the needs of temporary tasks as much as possible, that is, for the scheduled tasks, the execution time, execution antenna, etc. can be adjusted within the scope of the original application information. Appropriate adjustments are made, but cancellation of scheduled tasks is not allowed without special circumstances
