The Exoplanet group in Ondrejov, CZ was founded in 2016. The astronomical Institute Ondrejov operates a 2-m telescope equipped with an Echellespectrograph. In the seminar an overview about the potential of our ground based support program for exoplanetary missions will be presented along with first results from 2017/2018 campaign. Furthermore, our institute in cooperation with Tautenburg Observatory and Universidad Catolica de Chile plans to design a new spectrograph for 1.52m telescope at ESO La Silla observatory, Chile which should contribute to candidate vetting process for PLATO in the future and most certainly also for TESS.
