Abstract

The Giant Magellan Telescope (GMT) is a complex observatory with thirty major subsystems, many low-level subsystems, components, external contracts, and interfaces. Almost all subsystems require software and controls to operate. An important goal for GMT is to have software and control subsystems that are easy to develop, test, integrate, operate, and maintain. To provide consistency across all controlled subsystems, a set of standards and a reference architecture are provided. Software components are specified using a Domain Specific Language (DSL), which enables code-generation in several languages and automatic validation of architectural conformance and interfaces. Some of the main observatory control subsystems have already been modeled using this approach, and initial implementations are currently being tested. The most advanced control subsystem is the primary mirror Device Control System (M1 DCS), which is currently under testing before the integration of the optical mirror in the test cell. This paper describes the status of the GMT control system, the main lessons learned, and the future steps in the development of the GMT control system.
