【摘要】 随着对地观测技术的进步以及人们对地球资源和环境认识的不断深化,遥感卫星技术的在面向小型化,多星组网等方向发展。中科院对地观测中心遥感卫星数据接收站网就是面向多星多任务建设的可覆盖全国的地面接收系统。面临着当前各接收站实际接收的卫星数据任务不断增多的现状,遥感卫星接收任务管理需要面向多站多星的任务模式,快速有效的制定各接收站的卫星接收计划,科学合理的调用地面系统资源。而如何摆脱原有模式,采用相对开放、开发效率较高的高精度轨道计算模块以实现卫星过境预报和卫星点位计算等核心功能,成为新的系统设计中急需解决的问题。首先介绍目前遥感卫星数据接收站网现状与问题,针对多站多星任务管理模式,讨论基于STK的遥感卫星接收任务管理系统设计的必要性。在此基础上,分析遥感卫星接收任务管理系统的主要功能和核心流程。然后采用模块化方法,对任务管理和设备监控等核心子系统进行设计。其中重点讨论在卫星接收任务管理系统中集成STK的卫星轨道计算及任务演示的实现方法及接口设计。最后本文将对系统的扩展性和系统的实施效果进行分析,并对STK在相关领域的应用进行展望。更多还原

【Abstract】 With the development of the earth observation technology and our constant deepening of understanding on the earth resources and environment, the remote sensing satellite technology develops towards downsizing and multi-satellite networking. The Remote Sensing Satellite Data Receiving Station Network of CEODE.CAS is a ground receiving system constructed to cover the entire country towards multi-station and multi-satellite.Facing the situation of more and more satellite data receiving tasks,The task model of multi-station and multi-satellite is required for remote sensing satellite data receiving task management, satellite data receiving plans for these receiving stations need to be formulated quickly and efficiently and the ground receiving system resources could be used scientifically and reasonably. While how to get rid of the original model and adopt more open, more efficient high-precision satellite orbit calculation modules to realize such core functions as satellite transit forecast and satellite point calculation has become the urgent problems to be solved in the new system design.In this paper, the current situation and problems of the remote sensing satellite data receiving stations is described first. The design necessity of a STK-based remote sensing satellite data receiving task management system for the task management model of multi-station and multi-satellite is discussed, based on which, the main functions of the remote sensing satellite data receiving task management system and the core processes such as satellite transit forecast and satellite point generation are analyzed. Then such core subsystems as task management and equipment monitoring are designed by a modular approach. Emphasis is laid on the satellite orbit calculation of integrated STK in the satellite data receiving task management system, the realization method for task demonstration and the interface design. Finally, the extensibility and the implementation effect of this system are analyzed and prospects on application of STK in relevant fields are made.更多还原
