Abstract

Very long baseline interferometry (VLBI) is one of the technologies to enable comparisons of atomic frequency standards at intercontinental baseline. Our group is working on development of wideband VLBI system with transportable small diameter antennas for VLBI application to the frequency transfer. The system is composed of pair of small diameter antennas and large diameter antenna, which observes ultra-wide frequency range at 3-14GHz. This paper reports the overview of the project and current status of the development.
