KOMPSAT-2 MSC DCSU Recording Mechanism

The DCSU performs satellite payload data acquisition and storage functions before sending the data to the ground station. While imaging, the DCSU makes a file per each input channel and store into memory stack. For the successful imaging mission, proper DCSU mission parameters should be uploaded before the mission such as file name, file size, output channel for the download transmission and so on. This paper will describe the DCSU recording mechanism and some notices that might be helpful for the ground operators.
