Abstract

The Extremely Large Telescope (ELT) is a 39 meters optical telescope under construction in the Chilean Atacama Desert. The control software is under advanced development and the system is slowly taking shape for first light in 2028. ESO is directly responsible for coordination functions and control strategies requiring astronomical domain knowledge. Industrial contractors are instead developing the low-level control of individual subsystems. We are now implementing the coordination recipes and integrating the local control systems being delivered by contractors. System tests are performed in the ELT Control Model in Garching, while waiting for the availability of individual subsystems at the telescope. This paper describes the status of development for individual subsystems, of the high-level coordination software and of the system integration on the ELT Control Model (ECM), focusing on testing and integration challenges.
