Geostationary radiatively-cooled telescope (GROT) Original Research Article

A possibility of the survey experiment onboard the geostationary GOMS-Electro spacecraft comprising the 15cm-telescope 1:1.8 and the in-flight-tested radiative cooler is considered. With presumed CCD performance the limiting stellar magnitudes V=16 and K=12 would allow regular daily monitoring of variable and high throughput observations of extended sources as well as environmental studies of the near-Earth and near-Earth-orbit space in the wide FOV 2 deg.
