Telemetry Data Processing Method Research And System Implementation

Telemetry data processing system plays an important role in space mission,and it is an important means to ensure the safety test and improve the work efficiency.At present,in order to enhance the reliability of data telemetry processing of aerospace products in the process of testing,requirements for aerospace range independent processing of the telemetry data processing results,and the results of the Department of aerospace products and real-time comparison.The telemetry data processing system developed by the aerospace product department is difficult to be fixed and the scalability is poor.The newly developed telemetry data processing system for space flight range is oriented to all space missions.Therefore,the telemetry data processing system of the new space range must have good expansibility and meet the other tasks and practical needs of the field test.Aiming at the above problems,this paper studied several key algorithms of space telemetry data processing system in the development process,in order to telemetry data processing performance,versatility and ease of use has improved,to meet the needs of the aerospace telemetry data processing range.The main contents of this paper are as follows:(1)The space task telemetry data storage method and the main existing problems,using data storage method based on the buffer pool,solves the storage problem of single space telemetry data,to achieve the classification of telemetry data storage space.(2)The characteristics of different types of task space telemetry data type,data type and data processing methods based on the data processing method based on dynamic database,aerospace telemetry data processing needs the ability to adapt.(3)The frequency control method of remote sensing data based on mark bit is adopted to solve the problem of output frequency control of telemetry data in space range.(4)A kind of telemetry data processing scheme is designed,which is adaptable to the space range.The results show that the method for the space range can meet the needs.
