High performance control of these systems leads to the need to predict the disturbance in order to better compensate for it. In this presentation, I outline the minimum variance control and modelling strategies developed in our team. What are the most suitable models for predicting turbulence, how to identify them, is it problematic to use physical priors, how to ensure the stability of the control loop, how to update the model-based controller smoothly during operation to follow the changing observation conditions?

Today, potential markets range from the already bustling amateur astronomy scene to rapidly growing wide scale industrial applications.[[BR]][[BR]]We at Tuparev !AstroTech and Astrosysteme Austria are involved in projects spanning this whole spectrum. On the industrial side, the increasing amount of satellites in orbit and the rising amounts of space debris mean the space around the Earth could rapidly be rendered unusable. As part of this effort, we are attempting to create a large, worldwide network to monitor satellites and space junk, covering regimes not included in the current generation of monitoring programs.[[BR]][[BR]]We are involved in every step from manufacturing and setting up the telescopes, to developing the pipeline for detecting and determining properties of such objects, through to the expected petabyte database management. For amateur and professional astronomers, we are developing a range of inter-connected, modern astronomy tools and applications as well as being involved in renovating old observatory facilities as well as locating potential sites for new observatories.[[BR]][[BR]]In this talk, I will give an overview of some of the projects we are involved in as well as some of the wider market out there.
