Abstract

The invention discloses a method and a device for extracting telemetry original code values ​​from original code frames. The method includes: acquiring externally input telemetry processing configuration information; formatting the telemetry processing configuration information to generate a single-byte processing unit set; wherein, the single-byte processing unit set includes a byte offset , mask, shift amount, sub-original code; according to each said byte offset, each said mask, each said shift amount and each said sub-original code, said original code frame is processed , to generate the original code value of the telemetry parameter. The present invention can be applied to ground satellite decoding applications of various satellite types, and can reduce workload and save cost in satellite decoding processing.

Description

technical field [0001] The invention belongs to the technical field of satellite telemetry decoding, and in particular relates to a method and a device for extracting telemetry original code values ​​from original code frames. Background technique [0002] At present, the number of satellite launches is increasing year by year, and satellite applications are becoming more and more abundant and more appropriate in people's daily life. To obtain the working parameters and environmental parameters of each system on the ground, the telemetry processing must be performed on the original code frames uploaded from the satellite to the ground. Telemetry processing first needs to extract the corresponding byte data of the parameter from the specified position in the original code according to the encoding method of the original code data of the specific spacecraft telemetry, and then obtain the engineering value of the telemetry parameter through various algorithm processing. [000...
