The control software for the Sardinia Radio Telescope

摘要

The Sardinia Radio Telescope (SRT) is a new 64-meter shaped antenna designed to carry out observations up to 100GHz. This large instrument has been built in Sardinia, 35 km north of Cagliari, and is now facing the technicalcommissioning phase. This paper describes the architecture, the implementation solutions and the development status ofNURAGHE, the SRT control software. Aim of the project was to produce a software which is reliable, easy to keep up todate and flexible against other telescopes. The most ambitious goal will be to install NURAGHE at all the three italianradio telescopes, allowing the astronomers to access these facilities through a common interface with very limited extraeffort. We give a description of all the control software subsystems (servo systems, backends, receivers, etc.) focusing onthe resulting design, which is based on the ACS (Alma Common Software) patterns and comes from linux-based, LGPL,Object-Oriented development technologies. We also illustrate how NURAGHE deals with higher level requirements,coming from the telescope management or from the system users.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
