| Abstract(in English) | VERA(VLBI Exploration of Radio Astrometry) aims at obtaining very high accurate position of galactic matter sources by using VLBI. To achieve such observations, it is required to observe phase of the sources accurately, therefore, we should compensate the effect of displacement of reflectors caused by gravity and phase errors of reciever. On the other hand, Horn-on-Dish method is proposed, which compensates the the errors by setting noise sources on main reflector. In this paper, we propose the principle of the method and how to apply to VERA. Further, we propose methods to eliminate displacement erros of sub-reflector from the metohd. |
