BECCAL Ground Control Software overview. Several software modules enable telecommanding (TC) and telemetry (TM) for controlling and monitoring the instrument. Inside the ground station (gray box) data are received from and sent to the ISS. Display modules enable the ground control personnel to supervise the experiment status and scientific data. All data are archived and stored in off-site backups. An external interface is provided to allow upload of new sequences and download of data for scientists. Logging and watchdog facilities ascertain that all essential software modules are always running
