<p>PROBLEM TO BE SOLVED: To unnecessitate a power supply line for supplying power from the inside of mobile body. SOLUTION: A tracking antenna system 1 has a plane antenna 11 for receiving signals from satellites, turning frame 13 to be turned with a turning shaft part 12 for azimuth angle adjustment as a center while mounting the plane antenna 11, and fixed base 14 for mounting the turning frame 13 and supporting it so as to freely turn it. Besides, a solar battery 2 for power supply is provided on the turning frame 13, and the solar battery 2 is deviated from the plane antenna 11 to the counter-clock-wise direction of azimuth angle direction about at 45 deg. and fixed while inclining the elevation angle about at 45 deg.. Therefore, when the plane antenna 11 is turned southwest in the direction of satellite while the tracking antenna system 1 is operated, the solar battery 2 always turns south so that the area of execution can be used wider than the case of fixing the solar battery 2 is fixed on the plane. Thus, efficiency is improved and the solar battery 2 can be more miniaturized.</p> |
