1 Introduction
The sat-nms Antenna Control Unit is an antenna controller / positioner with optional satellite
tracking support. It may be operated as a standalone unit or in conjunction of the sat-nms ACU-
IDU, a PC based indoor unit which offers extended tracking capabilities and a full featured
visualization interface.
The sat-nms ACU is available as:
sat-nms ACU-ODM: only the core-module integrated in a compact case prepared for
mounting on a 35mm DIN rail
sat-nms ACU-ODU: complete antenna controller system for AC- or DC-Motors integrated in
an outdoor cabinet that could be mounted directly to the antenna. By mounting a sat-nms
LBRX beacon receiver into this cabinet, you have a complete antenna tracking system in a
