Positioning Systems
ARA, Inc.'s Wide Band Unit (WBU) offers an ever-expanding line of positioning systems based on mature, robust, digital motion control architecture and mechanical systems designed to satisfy the most demanding applications. Most systems use brushless DC servo-motors with integral resolvers for velocity feedback and separate absolute encoders coupled directly to the output for position feedback information. This dual loop feedback system is tightly controlled by a specialized motion control system that provides precise speed and positioning capability.
Antenna Research positioning systems have been used successfully on both military and commercial applications. Many of the controllers and positioners have been qualified to MIL-STD-810 for Environmental Testing and MIL-STD-461 for EMI/RFI and are successfully installed in ground- based, shipboard and airborne applications.
The ARA, Inc. positioner product line is subdivided into the following categories:
- Single Axis Positioners (ARP Series)
- Elevation over Azimuth Positioners (EAP and EAR Series)
