  Every single action that happens on a satellite is documented in log files. We use antennas to download these log files, and then use software to check them to make sure everything is ok. When the spacecraft is over one of our antennas, we can get live information from the spacecraft about what is happening on-board, and we can send commands to it if we need to.
