Title: Attitude controllor for antenna on moving body
Inventor: KATO EIJI
IPC: G01S3/44
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the disturbance and the tracking deviation of the attitude of an antenna by providing an inhibiting means for inhibiting the attitude change with a control means in response to the detection of an attitude-change detecting means. CONSTITUTION:An attitude-change detecting means 30 detects the attitude change of a moving body with respect to a radiowave source. A control means 4 drives a BS antenna Ant through driving means 141 and 151 in the direction for correcting the attitude deviation of the antenna Ant with respect to the radiowave source due to the attitude change of the moving body with respect to the radiowave source in response to the attitude change detected with the means 30. When the shock of the moving body is detected, an inhibiting means 4 inhibits the change of the antenna attitude in response to the detection of the means 30, namely, the abrupt change of the antenna attitude in response to the high-level output of the means 30 caused by the shock during the presence of the shock. Therefore, the large disturbance of the antenna attitude and the tracking deviation by the shock, when, e.g. a vehicle passes the projection or the depression of the road, are prevented.
