We introduce and describe our newly developed code that simulates light curves and radial velocity curves for arbitrary transiting exoplanets and its satellite. The most important feature of the program is the calculation of radial velocity curves and the Rossiter–McLaughlin effect in such systems. We discuss the possibilities for detecting the exomoons taking the abilities of Extremely Large Telescopes into account. We show that satellites may be detected also by their RM effect in the future, probably using less accurate measurements than promised by the current instrumental developments. Thus, RM effect will be an important observational tool in the exploration of exomoons.
