Abstract

We present and discuss the role of robotic telescopes in satellite projects, as well as related strategies. Numerous satellite projects in space astrophysics focus on high energy astrophysics from X-rays to gammarays. However, a large fraction of objects of high-energy astrophysics emit also optical light, which in many cases, are variables. The observation of these sources at optical wavelengths can provide valuable inputs for multispectral analysis of various categories of celestial high-energy (HE) sources. There are also satellite projects outside the high–energy astronomy, in which the robotic telescopes can also play an important role, e.g. the ESA satellite Gaia. In Gaia, robotic telescopes are expected to verify the triggers detected by satellite (such as transients and flares) but also to provide additional (mostly photometric) data for better scientific cases.
