<P>PROBLEM TO BE SOLVED: To set an optimum orientation of a directional antenna by automatically correcting the geodesic deviation becoming the reference of position information of a transmission side device and a receiver. <P>SOLUTION: In the receiver 60, candidate calculation means 65 determines a plurality of position candidates by converting the position information of a transmission side device 51 for a plurality of geodesic systems, with reference to relation storage means 66 for storing the conversion relationship among the plurality of geodesic systems. Adjustment control means 67 controls adjustment means 69 to change the orientation of a parabolic antenna 61 toward the plurality of position candidates, thus setting the antenna 61 to an orientation of highest reception level detected by level detection means 63. <P>COPYRIGHT: (C)2013,JPO&INPIT |
