<P>PROBLEM TO BE SOLVED: To obtain an antenna axis calibration method for solving the problem of time (restrictions caused by the observation time of weather and target radio satellite) and the problem of difference incurred in an antenna orientation angle in installing a plurality of antenna devices. <P>SOLUTION: In an antenna device for stationary orbit observation, an orbital position of each GPS satellite is calculated on the basis of TLE, and an antenna axis calibration value is calculated from a tracking result of tracking each GPS satellite on the basis of the orbital position and positional information of each GPS satellite acquired via the Internet. Therefore, the problem of time is mitigated and the problem of difference incurred in an antenna orientation angle in installing a plurality of antenna devices can also be solved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
