摘要:

现代卫星实验通常是非常复杂的实时系统,由飞行和地面部分组成,在尺寸、重量、功率、实时响应要求、容错和专用输入/输出硬件-软件方面具有挑战性的资源相关限制,并且必须经过高水平的保证认证。硬件-软件数据处理系统必须对系统退化和数据获取方式的变化作出反应,必须采取行动改变飞行任务的组织。由科学家和技术人员组成的团队进行大规模的研究和开发工作,可以产生能够优化硬件以达到非常高的性能水平的软件系统,或者拉低硬件以保持令人满意的功能。我们将展示描述一个系统的真实例子,在旋转模式下处理基于卫星任务的X射线探测器的数据。

英文摘要:

Modern satellite based experiments are often very complex real-time systems, composed by flight and ground segments, that have challenging resource related constraints, in terms of size, weight, power, requirements for real-time response, fault tolerance, and specialized input/output hardware-software, and they must be certified to high levels of assurance. Hardware-software data processing systems have to be responsive to system degradation and to changes in the data acquisition modes, and actions have to be taken to change the organization of the mission operations. A big research & develop effort in a team composed by scientists and technologists can lead to produce software systems able to optimize the hardware to reach very high levels of performance or to pull degraded hardware to maintain satisfactory features. We'll show real-life examples describing a system, processing the data of a X-Ray detector on satellite-based mission in spinning mode.
