遥感卫星星地对接试验系统的设计与实现

Design and Implementation of Compatibility Test System Between Remote Sensing Satellite and Ground System

星地对接试验是验证卫星与地面系统间控制接口、数传接口和数据格式的重要环节。针对当前遥感卫星星地对接试验过程中对接数据不能快速流转、缺乏统一试验系统调度与管理、急需软件系统支撑的现状,对星地对接试验内容和系统需求进行分析,通过引入工作流引擎技术,从系统框架、功能组成、工作流、系统界面及数据库等方面,设计并实现了基于工作流引擎的遥感卫星星地对接试验系统。系统可适应多型号遥感卫星星地对接试验,支持流程灵活定义、数据高效组织管理,提升对接试验效率。

The compatibility test between satellite and ground system is an important step to verify the control interface,data transmission interface and data format between satellite and ground system.During the current compatibility test,the compatibility data can not be quickly transmitted,and there is no unified scheduling and management of the test system,meaning that the software system support is very necessary.Therefore,the compatibility test contents and the system requirements are analyzed.With the workflow engine technology,a compatibility test system between remote sensing satellite and ground system is designed and implemented from the perspectives of system framework,functional composition,workflow,system interface and database.The system can adapt to the multiple types of compatibility tests between remote sensing satellite and ground system,supporting flexible definition of processes and efficient data organization and management and also improving compatibility test efficiency.
