| High Light | ANTEENA POSITIONER ，POSITIONER | ||
Antenna Positioner is a key part of antenna far-field measurement. Such 3-dimensional positioner system is composed by azimuth axis, pitching axis and polarization axis. Tested antenna is fixed on the installation surface of the polarization axis, and the positioner can accurately change the mechanical point of the antenna in space, in order to achieve the 3-dimentional direction pattern.

The design ideas of such positioner are:
a) Positioner’s configuration: It adopts U-T framework structure, and the
framework is made up of welded steel plate components, which
ensure a sufficient strength and stiffness conditions of the components.
And it also greatly reduce the moment of inertia of the axises.
b) Dragging device: it adopts Japanese Yaskawa AC servo motor
c) Sensor: it adopts high-precision optical encoder as the angle sensor, in
order to achieve high-precision control of the positioner.
d) Control program: it adopts PC digital control to achieve full control function. The control system of the positioner contains a control PC, which is a direct control device of the positioner, to achieve high-precision and high frequency control requirements. The control PC, as a man-machine interface, adopts WINDOWS operation system, with a friendly interface, easy for operation and management.
