CCSDS system satellite telemetry packet classification extraction method and system, and medium

Abstract

The invention discloses a CCSDS system satellite telemetry packet classification extraction method and a system, and a medium. The method comprises the steps: 1, obtaining the feature attribute of a telemetry frame structure and the feature attribute of a telemetry packet structure which are generally defined by a satellite model; step 2, obtaining a telemetry frame category attribute to which a target telemetry packet to be processed belongs and category attributes of all the target telemetry packets; 3, acquiring an input and output file path; 4, reading the original telemetry data of the satellite according to the obtained input and output file paths, and initializing the current file processing position as the initial position of the telemetry data; 5, locking a telemetry frame; and 6,locking the target type telemetry frame. Aiming at a satellite model adopting a CCSDS subpackage telemetry system, the method is combined with parameter configurable automation and universalization design, and a rigorous judgment algorithm for irregular cross-frame telemetry packets is adopted, so that the high efficiency, accuracy and comprehensiveness of telemetry data analysis are realized.

Description

technical field [0001] The invention relates to the technical field of satellite data processing, in particular to a method, system and medium for classifying and extracting satellite telemetry packets in the CCSDS system. In particular, it relates to a method for efficiently classifying and extracting telemetry packets in satellite telemetry data based on the CCSDS telemetry system. Background technique [0002] A telemetry frame is the standard unit of transmission for satellite telemetry data transmission to the ground. The satellite telemetry data using the CCSDS sub-packet telemetry system is collected by the satellite satellite service system from the corresponding interface to form a telemetry packet, and then the telemetry packet is continuously inserted into the telemetry frame, and finally a complete telemetry frame is formed. down to the ground. [0003] Telemetry packets are identified and differentiated based on the source of the packet data. With the develop...

AI Technical Summary

Problems solved by technology

The ratio of the data volume of the front and rear parts of the cross-frame packet is irregular, and the existing manual analysis methods cannot directly search and analyze these irregular cross-frame packets, which will cause data omission

[0005] To sum up, the existing manual analysis methods for telemetry packet data are not only inefficient, but also cause data omission, which cannot meet the current needs of efficient, accurate and comprehensive analysis of telemetry data.
