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 main structure is defined as the telescope mechanical structure including the drives, the encoder system, the hydrostatic bearing system and all those subsystems which make the system self standing safe and testable as an electromechanical system

The prototype of an optical gyro encoder (OGE) has been successfully tested on the NTT telescope in September '93. The OGE consists of a ring laser gyro and a fiber optic gyro with their input axis parallel. The gyro outptu signals are compensated fo

The Very Large Telescope (VLT) utilizes high accuracy absolute encoders for the altitude and azimuth axes. The size of the telescope makes it impossible to use encoders of the glass disc type, like have been used on the ESO NTT telescope. The solutio

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 altitude and azimuth axes of the VLT telescopes will be controlled by special designed servo controllers. These controllers are designed to minimize the effect of disturbances. The properties of all elements of these servo systems: mechanical sys

Fiber Optic Gyros: 15th Anniversary Conf.
An investigation is underway regarding the usefulness of altazimuth-mounting telescopes' incorporation of laser gyros for pointing and fiber gyros with extremely small random-walk coefficient for telescope inertial stabilization during tracking. A st
