The Square Kilometre Array (SKA) will be the world's largest radio telescope once it is complete and will use hundreds of thousands of receivers, spanning Africa and Australia to survey the sky in unprecedented detail. The SKA will be ground breaking in many respects such as image resolution, sensitivity, survey speed, data processing and size to name a few. The SKA Telescope Manager Consortium is currently designing the SKA Phase 1 (SKA1) Telescope Manager Element that will orchestrate the SKA Observatory and associated telescopes. In this paper, we report on the current status of the SKA1 Telescope Manager pre-construction project, the development process and its high-level architecture.

MOD3O06	Interface Management for SKA Telescope Manager	68

	The Square Kilometre Array (SKA) project is currently in the Pre-construction Phase. During this phase, the telescope subsystems are being designed. The Telescope Manager (TM) is a supervisory control and monitoring subsystem in each of the two radio telescopes of the SKA (SKA1-Low and SKA1-Mid). The TM interfaces with a number of diverse telescope subsystems. Interaction between TM and these subsystems is a major source of requirements for the TM. Careful management of TM external interfaces is therefore important. This discussion is a case study of TM interface management. Firstly, how system architectural design aspects like separation of concerns in the control hierarchy reduce telescope complexity with regards to interfaces is discussed. Secondly, the standardisation approach for monitoring and control interfaces to facilitate early elicitation of interface requirements for the TM, and to manage the diversity of interfacing subsystems is discussed. Thirdly, the relations between interface definition and requirements analysis activities, using SysML representations as an example is discussed.

	The Square Kilometer Array (SKA) project aims at building the world's largest radio observatory to observe the radio sky with unprecedented sensitivity and collecting area. In the SKA1 phase of the project, two dish arrays are to be built, one in South Africa (SKA1-Mid) and the other in Western Australia (SKA1-Survey). Each antenna will be provided with a local monitor and control system, enabling remote operations to engineers and to the Telescope Manager system. In this paper we present the current status of the software system being designed to monitor and control the dish subsystem. An overview of the dish instrumentation is reported, along with details concerning the software architecture, functional interfaces, prototyping and the evaluated technologies.
