The Design of Automated Validation System for Satellite Data Transmission System Based on AOS

In order to satisfy data transmission in space data system, advanced orbiting systems(AOS) is proposed by consultative committee for space data systems(CCSDS). According to AOS space data link protocol, data transmission system in satellite is used to transfer valid data of different type from space to ground. Although there exist some validation systems for data transmission system, they can be applied to some specifical satellites only. In this paper, based on space communications protocols reference model, we propose an automated extensible validation system for satellite data transmission system, while the valid data from different virtual channel are separated exclusively in real-time, to be read by different processing and analyzing software. After configuring instructions appropriately in control and analysis equipment, which acts as the interactive interface, the system checks the data automatically. Validation results demonstrate that, the proposed automated validation system works well when receiving AOS transfer frame at rate of 800Mbps with seventeen virtual channels.
