Abstract
Meteorological satellite ground application system business operation scheduling is the core of the entire business operation, directly related to the entire system operating efficiency. This paper designs a hierarchical satellite terrestrial system business operation scheduling method. First of all, the satellite service is classified into first-level and second-level scheduling. Then, based on the hierarchical scheduling, task scheduling and scheduled scheduling are implemented. Through hierarchical scheduling and planning and scheduling to achieve the entire system job scheduling, thereby enhancing the efficiency of task scheduling and improve the overall system operating efficiency.
Highlights
Each system of polar orbit meteorological satellites needs to be able to collaborate with each other such as receiving, transmitting, processing and archiving
A satellite periodic continuous observation task scheduling algorithm based on multiobjective evolutionary algorithm was proposed
The paper [5] proposed a two-phase task scheduling algorithm to enhance the performance of scheduling, including an initial scheduling phase and a dynamic scheduling phase
Summary
Each system of polar orbit meteorological satellites needs to be able to collaborate with each other such as receiving, transmitting, processing and archiving. The paper proposed a solution to determination of the minimum execution time to run the N-version of the control system of a satellite communications system for a given number of processors. The paper [2] proposed a novel dynamic fault-tolerant scheduling model for real-time tasks on multiple observation satellites. In this model, the primary/backup policy is employed to tolerate one satellite's permanent failure at one time instant. A satellite periodic continuous observation task scheduling algorithm based on multiobjective evolutionary algorithm was proposed. Based on the above research, this paper designs a hierarchical service scheduling method for satellite terrestrial systems. Based on the hierarchical scheduling, task scheduling and scheduled scheduling are implemented
