APECS - The APEX Control System

APEX (Atacama Pathfinder EXperiment) is a 12m single dish submillimeter telescope at 5100m altitude near the ALMA site on the Chajnantor plateau in Chile. The APEX Control System (APECS) provides telescope control, instrument configuration, raw data acquisition and data calibration which is handling observing sequences (e.g. on/off) and instrumental or atmospheric corrections. It also implements automatic observation and device parameter logging. The user interface is based on Python and allows for efficient scripted observations.
Due to the generic interfaces, APECS has been able to accommodate all facility and PI instruments during the past 15 years. In recent time many improvements were made to handle the ever increasing data rates and volumes. New calibration schemes can cope with the very wide bandwidths of current and future instruments. APECS was also adapted to use the new wobbler and hexapod of the APEX-II upgrade.
Future developments will address porting the software to Python 3 and migrating the real-time computer to a modern platform.
