“…The MC executes the OFPs within a fixed time interval, known as a time slice, at a rate of 20 to 60 Hz [3]. At the start of a time slice, the MC receives data from the subsystem and begins the data manipulation after the data receiving step is completed.…”

“…Various functions required for control, operation, and management are supported by several computers, sensor, actuator, and display units, which are integrated and connected to a data bus in the aircraft [2]. In particular, MC is recognized as a core avionics unit that receives flight data and processes this information within a restricted time interval [3] [4]. The amount of data delivered to MC has gradually increased because MC is forced to perform diverse composite missions.…”

In this paper, we propose an efficient data transmission scheme for the real-time operation of mission computers (MC). The amount of flight data transmitted to MC has gradually increased as the performance of aircraft has improved which makes it difficult to satisfy the real-time constraint required for the MC. In order to overcome this problem, we develop a new data format and transmission algorithm by investigating ARINC-429. The proposed scheme is verified by observing the performance on the test platform based on real-time OS. The experimental results show that the proposed scheme achieves a computational time gain of 13% and a transmission data gain of 34%. In addition, the proposed scheme will be useful for extending the life of MC without changing the existing H/W.

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.
