Abstract

Abstract

The data packets obtained by satellite are stored in bits or bytes and their storage formats are defined by hardware engineers. When the data is telemetered to ground and the same data packets will be organized into a binary format file. So, a large amount of files will need to be decoded into readable format files. Although their storage formats for different satellites or payloads have different styles, they can be decoded by the same rule. This work will introduce a decoding system including an interface module and a decoding module. The interface module is used to store their storage formats to database and makes it a very convenient way to communicate between hardware engineers and software engineers. And a decoding module will be used to decode the data packets based on the data storage formats form database. This decoding method will save much time and labor cost.
