Monitoring And Control Of The Answering Machine And The Skin Of Satellite Engineering Research

Pico-satellites have advantages of high self-control degree, low weight (1kg or lighter), small size, high functional density and short R&D period. It can be used in communication, navigation and deep space exploration. It has been a hotspot for many countries after normal satellite. "One-rocket-several-satellites" is usually adopted as the launch method for Pico-satellites. The satellite cluster in the satellite orbital covers some range in the way of formate. Satellites share resources and information with each other, realize functions together, such as stereo imaging, distributed aerospace measure, etc. And they can realize space science experimentation with lower cost, such as satellite carry test.Our group has been researching on MEMS Pico-satellite for several years. Up to the present, the satellite has realized most functions and accorded with the design performance. One of the satellite samples will be launched. My major contribution to the satellite during my master period includes three parts: designing and debugging the final version of TT&C transponder; debugging the whole satellite and passing reliability experiment; theory analyze about velocity measure of the pico-satellite. Main features of this paper are as follows:1. Final version of TT&C transponder is designed and debugged which is based on former versions. The new transponder is applicable to be launched, and results of tests met design spec.2. The method for measuring velocity of the pico-satellite is analyzed. And this method is tested by series of experiments which is simulated as the satellite's real orbit. The results show the transmit ability of transponder accord with velocity measure requirements.3. The principles of the pico-satellite are introduced. After all the subsystems were tested to be regular, the whole system realized all functions in series tests. And we got the wireless communication data.4. The Pico-satellite passed the reliability experiments including temperature circulation experiment, vibration experiment, particle radialization experiment, and thermal vacuum state experiment. The results showed that the pico-satellite met the launching and orbiting demandsBased on research and experiments, the final version of S-band TT&C transponder of pico-satellite is designed and debugged, the performance met the design spec. Velocity measure is analyzed, and the method and performance tests results are also introduced. The Pico-satellite has passed the reliability experiments, too. All these results indicate that the MEMS pico-satellite realize lots functions, reach the design specification and even outperform it, and can be launched soon.
