The Automated Test System Of High Speed Data Transmission System Based On Satellite

The satellite testing synthesizes collectivity testing and sbusystem testing. System testing is a complex process for data transfer system.At present, the satellite of our country mainly adopt the CCSDS protocol, which provide a better base for satellite control and data system.. COS and AOS were developed for using in the civil space. The capability of satellite data system contain several targets, and one of the most important capability is probability of wrong code. Ground automatic test platform of data transmission system,which is based on CCSDS high- speed remote sensing satellite。The main technique of satellite auto testing system is still traditional circuit technology in China. The function of product is defined by the supplier, and because of the high rely on the supplier, the function can be hardly changed or recycle-used. The highly developed fictitious instrument technology is widely applied in the field of spaceflight abroad, and it has also been successfully used in China recently, however, the system is in need of further optimization. The typical characteristic of fictitious instrument technology is the equation of software and instrument, and the system function is defined by the subscriber. The above characteristic will save production cost and raise working efficiency when it is used in satellite testing.This article elaborated one kind of automated test system using to test the data transmission system on the satellite. Now days, the data transmission system has a greater capacity and t higher transmission speed. This test system makes the function and performance index test becoming more effective. This test system was designed under the suggestion of CCSDS, which is the consultative committee for space data systems. This test system includes three sub-systems which is Telemetered data interpret subsystem, Radio frequency automation test subsystem and Baseband automation test subsystem. The goal of designing this system is to establish a test platform of general space data.
