“…Modules and functions of MSA are summarized from a generally used perspective. There are four main subsystems of MSA: [21][22][23] communication system (COMS), guidance, navigation and control (GN&C) system, command and data handling (control and data handling, C&DH) system, and vehicle management system (VMS). COMS is just like ears and throat of a spacecraft which receives instructions from the ground control center (GCC) and transmits the science and status data to the GCC.…”

This article presents a condition assessment model to evaluate the health condition of manned spacecraft avionics that enables the essential capabilities of a manned spacecraft and guarantees the mission success of space flight. Condition assessment based on the integrated system health management is introduced into manned spacecraft avionics to cope with the safety and maintenance necessity. Due to the complexity and the uncertainty of the system, it is a tough task before modular avionics emerged, and there is a rare research-concerning condition assessment for manned spacecraft avionics with fuzziness and simultaneous consideration in system level. A numerical example illustrates the proposed fuzzy evaluation model which takes all criteria into account from a holistic perspective, combines objective tests with subjective judgments and incorporates fuzziness and uncertainty into ranking the manned spacecraft avionics health level using fuzzy analytic hierarchy process with quantitative reliability analytical approaches. The proposed model is demonstrated to solve the condition assessment problem and the impact condition factors for the manned spacecraft avionics health management are revealed.

“…Therefore, the health of the MSA is directly related to flight safety and mission success . For a manned spacecraft to accomplish all tasks, the on‐board condition of the MSA needs to be determined accurately and in a timely manner . To deal with these complex safety and maintenance issues, an integrated system health management (ISHM) system is used …”

The purpose of this study is to develop a prediction methodology for a condition assessment of on-board integrated health management systems in manned spacecraft avionics. The framework of this study is based on two main premises. The first is the need to examine the problems in the on-board prediction tools in space avionics integrated system health management, an area that has been rarely focused on. The second is the need to consider the failure correlation coefficients to enable accurate health predictions. To deal with the uncertainty in the prediction process, a fuzzy theory-gray model-support vector machine approach, which uses fuzzy theory combined with a gray model and a support vector machine, is used to make the prediction. An example is given to demonstrate the accuracy and reliability of the model.

Avionics systems have become the information backbone of modern Aerospace systems ranging from micro‐air vehicle and nano‐satellite to jumbo jet and advanced spacecraft. With origins in vacuum‐based radios, the rapid evolution of electronics and software has enabled the development and integration of sensing, processing, and communication elements to perform a wide variety of monitoring, control, and communication tasks. This chapter overviews avionics systems for air and space systems, summarizing the functionality, technologies, and interfaces that have evolved. Although mission objectives and avionics designs differ from air to space systems, both rely on a common suite of interdisciplinary technology areas, including electrical engineering (sensors, communication devices, and power systems), computer engineering (processors and networks), software engineering (including validation and verification), control systems engineering (including guidance, navigation, and control), and human factors (cognitive engineering, life support). Training and education concerns are also discussed in the context of preparing engineers and pilots to design and operate next‐generation avionics systems. Avionics technologies, existing and emerging, are summarized here at a system‐level; further details of avionics subsystem technological capabilities and needs are referenced in other Encyclopedia Chapters (Embedded UAS Autopilot and Sensor Systems through Space Human Factors and Operator Interfaces).
