The Application Design of SOIS Electronic Data Sheets in Onboard Integrated Electronic System

Abstract

This paper analyzes the concept and research status of SEDS (SOIS Electronic Data Sheets) in the field of Spacecraft Onboard Interface Services (SOIS) of Consultative Committee for Space Data Systems (CCSDS). In order to achieve fast integration and testing of the onboard software, this paper discusses how to apply the SEDS standard in the onboard integrated electronic system of Chinese spacecraft. This paper shows the structure of the onboard integrated electronic system, the stratification of the structure, and the functions, services, protocols, and components of each layer. Based on the architecture of the system, the top-level application design of SEDS in the process of the development of onboard integrated electronic systems is presented, Taking the remote sensing and acquisition function of spacecraft as an example, the design and application examples of SEDS and the subsequent expansion methods of SEDS are given. The SEDS is used as input in the development and testing of spacecraft integrated electronic system software. The results show that the application of SEDS is helpful to realize the standardization of onboard interface and promote the spaceborne integrated electronic system and even the whole spacecraft research through automatic code generation and electronic data reuse. Shorten the system cycle.
