Research And Implementation Of Micro-satellite Tower Test System Based On ARM

Nowadays, with the fast development of high and new technology, Sat-Test on Tower need to be improved. Before the launching of the Micro-satellite, satellite must be tested because of the insurance of the satellite reliability. The tranditional test equipment is actually designed for ground integral test and have many shortages to Sat-Test on Tower such as big size of equipment, density of package,saperated function modul and so on.Represented with ARM,performance micro processor is pushing forwards the embedded system to the era 32-bits processor. Although a variety of ARM pruducts are seen everywhere.they are mainly exploited on Windows platform currently.In this paper,the built of ARM compile system with Linux platform is investigated.According to Micro-satellite Tower Test requirement, one test system based on ARM is specified. The system is mainly composed of two parts:fore-end data collector and back-end control computer. It has highly reliability, automatically, easy usebility, portability, flexibility.In this paper, an ARM-based embedded system is researched with the background of a practical satellite measurement project. The hardware design of the system based on ARM is accomplished.The process of ARM-based embedded software developed in Linux GCC environment is represented. Besides, the supervising program with multithreading technology based on Windows plantform is designed. A simple but effective fault diagnosis expert system is designed.In the end, the summary and prospect for the system is given in the papar.
