Abstract:
All telemetry data generated on a low earth orbit satellite are stored in a mass memory and downlinked to the ground together with the real time data during the contact time. The playback telemetry data are stored in the ground station as a playback raw data file, which includes all types of telemetry frames. The file should be analyzed if there is any error in telemetry format and frame sequences. And also, it needs to separate the file by each frame type, and combine or split the playback files by the size or by the time for the convenience of the post processing. The playback data analysis utility is developed to perform the above requirements. It can be used for analyzing the playback data file generated by the ground test equipment during the ground test phase, as well as the real playback data file received from the satellite. This paper shortly introduces the telemetry data storage and downlink operation in a low earth orbit satellite developed in Korea, and presents the playback data analysis utility program.
