Optical observations represent important part of multispectral analyses of high-energy sources.
We develop and operate robotic telescopes and small ground-based telescopes, and in collaboration network of small and amateur observatories.
We focus on the development and operation of innovated ground-based telescopes for the astrophysical satellite projects, mainly robotic telescopes BART and BOOTES. BART is a Czech robotic telescope placed in the Astronomical Institute in Ondrejov. BOOTES is a system of two robotic telescopes operated in the framework of Spanish-Czech collaboration in favourable observing conditions of south Spain. It includes remotely controlled instruments directly connected to the international system of satellite data distribution (gamma-ray bursts) GCN. Both instruments already provided us with valuable follow-up data for gamma-ray bursts detected by satellites. Development of unique controlling software for the satellite and ground-based experiments (INTEGRAL OMC, INTEGRAL ISDC, BART, BOOTES).
