Advances in Stellar Interferometry.
The Very Large Telescope Interferometer (VLTI)1 that coherently combines the four VLT 8.2-m Unit Telescopes (UT's) is on the point to be fully equipped with its dedicated array of Auxiliary Telescopes (AT's). This array includes four 1.8-m telescopes

The VISTA wide field survey telescope will be operated and maintained from 2006 by ESO at their Cerro Paranal Observatory. To minimise both development costs and operational costs, the telescope's software will reuse software from the VLT wherever fe

The first VLT unit telescope, Antu, saw first light in May 1998 and started science operation in April 1999, roughly at the same time as first light of unit telescope 2, Kueyen, was achieved. The time between first light and science operation is used

Advanced Telescope and Instrumentation Control Software.
This paper presents the actual status of the Telescope Control Software on the VLTs and on the other telescopes. The main focus is in the characteristics that make the TCS architecture portable on very different mechanical and optical configurations.

The Field Stabilization functionality compensates for image motions, mainly due to wind gusts, with a frequency of up to 50 Hz. Position errors are detected with a CCD mounted in the guide probe, and the correction vectors are passed to the secondary

The installation of the complete VLT telescope control system on the observatory is a complex task. It is important that the various components of the system have been carefully tested and integrated before. This paper presents the ESO strategy to pr

The ESO VLT control software consists of all the software, which will be used to directly control the VLT Observatory and associated instrumentation. This is now in the implementation phase, performed to a large extent by ESO staff in the VLT softwar

The generation and distribution of an accurate time signal has been the cause of some technical difficulties in the past. Modern telescopes with their distributed computer architecture have increased this problem even more. Since the availability of

The design of the VLT Telescope control software is driven by requirements of different nature and origin: technical/astronomical requirements, operational requirements, test and maintenance requirements, and general system engineering requirements.
