The rotation of antenna in azimuth at very fast rate are detected by gyroscope (Tiezzi et al., 2012).The Gyro sensor can be used in precise attitude control (Kim et al., 2013). The rolling and pitching angles of receiving antenna are calculated by using gyro and inclinometer. The antenna...
The aerial drive unit 18 provides signals Ed, Ad, to the computer 22 which are representative of the angular position of the reflector 28 in relation to the (X A , Y A , Z A ) co-ordinate axes system. The computer 22 develops signals E Ed , E Ad in response to its various input...
The elevation-azimuth (or “el over az”) coordinate system described here has its lower plane of rotation (azimuth) parallel to the local horizontal plane. A weather radar antenna, for example, rotates on the azimuth plane. The second axis, the elevation axis, is at right angles to the ...

It is an object of the present invention to provide a wide range azimuth (AZ) driving system for an antenna which has a simple structure and enables costs to be lowered and a producing time to be shor
can be obtained. FIG. 5 is a diagram illustrating the relationship between the directional gain and the azimuth angle for the main polarization (elevation angle θ=90 degrees) at the resonance frequency (which is adjusted to be in the vicinity of 1.8 GHz) of the fundamental mode of the ant...
A three-axis antenna positioner has an X-Y over azimuth configuration, and includes an azimuth drive assembly, an X-axis drive assembly, and a Y-axis drive assembly. Each drive asse
