Two antenna units (11) and (12) are located on a pedestal device (13) provided rotatably around an azimuth angular axis thereof, and a rotating mechanism for rotating in an azimuth angular direction and an elevation angular direction respectively is provided in each of the antenna units (11, 12). The antenna units (11) and (12) execute, for the purpose of communicating with the orbital satellites (81) and (82) respectively, satellites tracking by adjusting its own azimuth angle and elevation angle while moving in association with rotation of the rotating mechanism (14) of the pedestal device (13).
