Paper Abstract

The ESO 8-meter telescopes, known as the VLT, utilize new technology in the design to achieve high image quality. Although previous telescopes have employed extensive component analysis and modeling, certain aspects of telescope performance are only captured by system level modeling. Therefore, to better understand design features on system performance, an end-to-end simulation model was developed jointly by ESO and Ball Aerospace. This required combining the diverse disciplines of structural dynamics, optics, atmospherics, control systems, signal processing, and random process modeling for disturbance generation into a single time simulation model. The end purpose of such at tool is to help in verifying requirements and performance for different VLT subsystems on one hand and to help understanding potential problems that could occur during the commissioning phase on the other hand. This paper describes the architecture and contents of the model, and gives some fist simulation results.
