MVG - Rotary Positioners - AZ/EL/ROLL / Null Seeker Positioner
The Null Seeker Positioner is used in development and production testing to emulate flight movement of a device encasing null-seeker sensors. Its high motion dynamics and ultra-precise angular positioning, rates, and acceleration allow for accurate evaluations of null seeker technology (ie. RF signal nulls transmitted from directive antennas).

More Product Information
MVG heavy duty azimuth positioners provide accurate rotation, velocity, and direction, with turntable diameters up to 122 in. (3100 mm). Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation.
MVG Performance Series heavy duty AZ/EL positioners represent the latest generation of multi-axis rotary positioning subsystems with turntable diameters up to 48.0 in (1,219 mm). They offer enhanced capabilities and improved performance relative to size and incorporate new engineering advances.
The EH022 EMC Horn combines stable gain performance and low VSWR with wide band frequency operation. The horn is single linearly polarized with excellent cross-polar discrimination. The unique horn design suppresses any possible excitation of higher order modes in the aperture and maintains a well-defined smooth radiation pattern in the direction of the boresight axis throughout the operational bandwidth.
MVG-Orbit/FR medium duty EL/AZ positioners provide accurate rotation, velocity, and direction, with platform sizes up to 28 x 28 in (711 x 711 mm). Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation.
