Abstract

The Square Kilometre Array (SKA) will host two radio telescopes in South Africa and Australia, each dedicated to observing at mid and low frequencies, respectively. The project has adopted the TANGO controls framework for its telescope control system. Both mid and low telescopes constitute subsystems whose components are implemented using TANGO monitoring and control and other bespoke as well as off-the-shelf software for the computing and network platforms. All devices are implemented in line with our SKA Control System Guidelines and with the aid of a shared repository for streamlined device server implementation. This ensures adherence to standards such as logging, asynchronous command execution, just to mention but a few. The components in the subsystems each implement a specialized behavior and state derived from the shared repository. The forthcoming discussion will outline how the TANGO controls framework is employed to implement the essential control elements for the SKA telescope. We will further detail our federated approach to implementing device servers which manage the different components.
