Abstract
This paper has designed the integrated electronic system and protocol architecture based on the standard of Consultative Committee for Space Data Systems (CCSDS) and European Communication Satellite System (ECSS). The application layer, application support layer, transport layer and sub network layer in the architecture can be described in detail, and the functions can be realized through the combination of various business and protocols. The architecture can provide technical support for the intellectualization and networking of spacecraft, standardize the spacecraft interface and protocol, it can promote the generalization of spacecraft equipment and software, and provide more flexible and powerful functions for the spacecraft.
Highlights
In order to improve the design level and R & D capability of our spacecraft, it is necessary for us to use the idea of information fusion design, to make use of standard interface and protocol specification to interconnect the satellite borne electronic equipment, and to create an integrated integrated electronic system with internal information sharing and comprehensive utilization, functional integration and resource reorganization and optimization
In order to solve this problem, this paper focuses on how to selectively apply Consultative Committee for Space Data Systems (CCSDS) standards and European Communication Satellite System (ECSS) standards in Chinese spacecraft, establish a standardized service and protocol architecture, form a unified information network service, and provide a technical basis for the intelligent and networked spacecraft
By analyzing the needs of remote sensing, navigation, communication, manned spaceflight and deep space exploration, we can conclude that the general requirements of integrated electronic system include 7 top level functions, which are remote control, telemetry, time management, internal affairs management, heat control management, power supply management, unlocking and rotating mechanism control
Summary
In order to improve the design level and R & D capability of our spacecraft, it is necessary for us to use the idea of information fusion design, to make use of standard interface and protocol specification to interconnect the satellite borne electronic equipment, and to create an integrated integrated electronic system with internal information sharing and comprehensive utilization, functional integration and resource reorganization and optimization. The system can achieve telemetry, remote control, energy management, heat control, attitude and orbit control, unlocking and driving control, intra satellite communication, time management, data management, load management, autonomous task planning, image location registration and motion compensation, which can achieve the purpose of general hardware modules, reasonable information flow, function density promotion and total optimization of body performance. In order to solve this problem, this paper focuses on how to selectively apply CCSDS standards and ECSS standards in Chinese spacecraft, establish a standardized service and protocol architecture, form a unified information network service, and provide a technical basis for the intelligent and networked spacecraft
