Design And Implementation Of Universal Measurement And Control Platform For Quantum Science Experimental Satellite

As an important part of satellite integrated test system,satellite ground test system is applied to the whole satellite test.It not only provides uplink and downlink channel for the whole satellite test,but also is an indispensable part in the whole satellite development and test.In this paper,the content of the satellite comprehensive test is introduced,the requirements of the ground test system are discussed,the architecture and working principle of the satellite ground comprehensive test system are analyzed in depth,and the environmental condition and test of the satellite test under different conditions are studied.demand.Then,the design of generalized and configurable ground test platform is designed.It consists of five parts: upper and lower frequency converter,front-end backend database,ground integrated baseband processing unit CORTEX(COMMAND RANGING & TELEMETRY UNIT),ground comprehensive test software.Through wireless and wired two kinds of test methods to send direct,indirect instruction and injection data,and receive from the satellite downlink telemetry data,as well as various types of telemetry and data analysis,display and storage.In this paper,the equipment composition,principle and function of the integrated test system are expounded in detail.Some key functional requirements such as telemetry and remote control,unification of satellite time datum,data storage and playback,BER test etc.A detailed understanding and analysis.This paper also studies the design method of measurement and control software,and proposes a system design which can adapt to the development of current measurement and control system.It mainly considers the mode architecture,information interaction and system operation,and establishes the whole software system.Which is mainly used to realize telemetry and remote control format,CRC check,frame synchronization and frame filtering of engineering data,telemetry data distribution,bit error rate test,star-earth delay test and so on.The system is divided into three parts:,Configuration database design aspects of content.In this paper,the important modules of the test platform are implemented at the code level,and the function functions are defined and coded in the specific modules.In the end,the performance of the test platform is tested in all aspects.Through all kinds of experiments,the function realization of the universal test platform can be verified and the testing platform can meet the requirement of satellite test.At the end of the paper,the whole design work is summarized,and the future work is forecasted.
