| 摘要: |
| 空天协同对地观测是对地观测领域的新趋势。为解决现有空天资源规划调度系统相对独立、协同困难的问题，分析总结了SWE（Sensor Web Enablement）标准，并在此基础上提出了空天资源对地观测协同任务规划服务模型。在此模型中，为实现观测资源共享，建立了空天观测资源传感器描述模型，能够描述典型空天资源的载荷平台、观测机理、定位信息、使用约束和工作特性等信息；为简化观测请求交互流程，基于SOA技术对SWE标准操作进行封装及简化，用户可以在不了解观测平台细节信息的情况下提交观测数据请求。为验证模型有效性，构建了空天资源对地观测协同任务规划实验平台，结果表明该模型具有较强的可实现性和适应性。 |

| Abstract: |
| The coordinated observation technique of air and space assets has been increasing in recent years and this trend of earth observation area is expected to continue in the future. A service model for space-aeronautics cooperation earth-observing operations is proposed after analyzing the SWE (Sensor Web Enablement) standard. In this model, in order to provide a common framework for air and space assets, the sensor model language of space-aeronautics observing resources was constructed. The primary focus of this language is to define processes and processing components associated with the measurement and post-measurement transformation of observations. Through introducing the inheritance mechanism, the proposed language can provide more robust definitions of platform, measurement, location, position, constraints and other characters. Besides, to shorten the data acquisition cycle, the standard interface of SWE was encapsulated, and a common end-user can request data directly without detailed knowledge of the platforms state and capabilities. To test the performance of proposed model, some experiments were designed and the simulations and analysis display the feasibility and the adaptability of the proposed model. |
