Abstract: The Observatorio AstronĂ³mico Nacional (OAN) is building a 40m radiotelescope in its facilities in Yebes (Spain) which will be delivered by April 2004. The servosystem will be controlled by an ACU (Antenna Control Unit), a real time computer running VxWorks which will be commanded from a remote computer (RCC) or from a local computer (LCC) which will act as console.

We present the tools we have chosen to develop and use the control system for the RCC and the criteria followed for the choices we made. We also present a preliminary design of the control system on which we are currently working. The RCC will run a server which communicates with the ACU using sockets and with the clients, receivers and backends using OmniOrb, a free implementation of CORBA. Clients running Python will allow the users to control the antenna from any host connected to a LAN or a secure Internet connection.
