ANTENNA DEVICE, ANTENNA COORDINATE INFORMATION CALCULATION METHOD, ORIENTATION INFORMATION CALCULATION METHOD AND HEADING ANGLE CALCULATION METHOD

摘要

PROBLEM TO BE SOLVED: To acquire the information (coordinate information) of the position (latitude and longitude) of an antenna device or the information of orientation easily from the information (coordinate information) of a plurality of positions (latitude and longitude) obtained from the same GPS receiver.;SOLUTION: By means of an antenna drive unit 2 for rotating an antenna 1 having a parabolic curved mirror 1a in which the GPS antenna 3a of a GPS receiver 3 outputting the information of latitude and longitude, around the azimuth axis, the antenna 1 is rotated around the azimuth axis. Coordinate information consisting of the latitude and longitude at two or more points, including that where the absolute value of difference of azimuth angles is 180° at the time of acquisition, is acquired from the GPS receiver 3.;COPYRIGHT: (C)2014,JPO&INPIT
