卫星地面任务控制系统的关键技术

摘要

Based on the analysis of task processing features of multi-satellite and multi-mission remote sensing satellite ground systems,a mission control system with good expansibility and universality was designed by introducing the task flow template, utilizing message management mechanism which combined database and message middleware and using the Spring framework and Expect scripts.The key technology of the system were demonstrated in detail.This mission control system can be applied to pro-cessing multi-satellite and multi-mission,and has good platform portability.It is suitable not only for centralized satellite ground system architecture,but also for distributed satellite system architecture.%在分析多星多任务遥感卫星地面系统任务处理特点的基础上，引入任务流程模板，利用数据库和消息中间件相结合的信息管理机制，采用Spring框架及Expect脚本设计具有良好可扩展性和通用性的任务控制系统，对系统中的关键技术进行详细阐述。该系统适用于多星多任务的处理，具有良好的平台可移植性，既适用于集中式卫星地面系统架构，也适用于分布式卫星地面系统架构。
