| Abstract: |
The Observatorio Astronomico Nacional (OAN) is building a 40m radiotelescope in its facilities in Yebes (Spain) which will be delivered in summer 2006. The radiotelescope is an instrument composed of antenna, receivers, backends, and auxiliary equipment connected through a Local Area Network (LAN). The control system has to deal with a distributed environment which needs to be remotely controlled and monitored from external heterogeneous users (astronomers and engineers) and requires multiple processes simultaneously working and being synchronized. We have chosen the Alma Common Software (ACS) framework for the development of the control system. ACS provides an implementation of the component/container paradigm via Common Object Request Broker Architecture (CORBA) and also provides general purpose utility libraries, hiding the complexity of CORBA to the developer. ACS is supported by the European Southern Observatory (ESO) and the National Radioastronomy Observatory (NRAO) for the Atacama Large Millimeter Array (ALMA) with a lifetime similar to our radiotelescope. This is an important guarantee for the OAN with a very reduced software team. We present an overview of the planned software architecture of the radiotelescope and the current status of the development of the components. |
