Abstract
The sat-nms ACU19V is an advanced automatic tracking antenna controller. It can be used
as a cost efficient antenna tracking system to replace the Vertex / General Dynamics
Satcom Technologies Model 7200 Antenna Control Unit keeping the outdoor 7150 Antenna
Drive Unit as it is. The replacement is simple plug & play by reusing the existing cables. The
system is based on the sat-nms ACU-ODM Module and provides Model 7200 ACU fully
compatible rear panel connectors in the 19inch 1RU chassis. The sat-nms ACU19V points
any antenna size precisely on the satellite and performs a fully automatic and accurate
inclined orbit satellite tracking with an improved adaptive tracking algorithm. The sat-nms
ACU19V records the tracked positions over several days and calculates based on this data
a precise mathematical model, which is used to predict the antenna position. This reduces
the step-track failures and provides continuous operation in case of a beacon receive
failure. In the Program Tracking Mode the antenna follows a path defined by a file that
contains time stamped azimuth, elevation and polarization values. These values have
usually been calculated by external software.
This document describes how to install, setup and operate this antenna controller.

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
(C) 2022, SatService GmbH www.satnms.com ACU-19V-UM-2209 Page 4/64

compact cabinet directly at your antenna.
sat-nms ACU-RMU: complete antenna controller system for AC-Motors integrated in a 6RU
19inch rack mount case for indoor use
sat-nms ACU19: complete antenna controller system for DC-Motors integrated in a 1RU
19inch rack mount case for indoor use
For detailed description please refer to the sat-nms documentation CD or www.satnms.com/doc
Main benefits of the sat-nms ACU are:
The ACU outdoor unit is able to act as a standalone antenna control and tracking system
without an indoor unit required.
The ACU provides an Ethernet interface using the TCP/IP and HTTP Internet protocols. It
can be controlled using any PC providing an Ethernet interface and a web browser like the
Microsoft Internet Explorer. The ACU runs a web server which acts as a user interface to the
antenna controller.
The ACU is prepared to read the receive level of a sat-nms beacon receiver through the
TCP/IP interface.
The flexible interface design of the ACU enables it to control most types of motor driving
antennas for geostationary satellites. Supported motor controllers are (configurable in the
field):
Power relays: This simple solution is suitable for antennas using 2-speed AC motors.
Freque ncy inv erters: Speed and acceleration ramps are programmed into the inverter
module with this solution.
Servo controllers: Used for DC motors at small antennas. Supported position sensors are
(separate hardware interface modules for each axis:
Resolver Interface: The resolver interface module contains a resolver to digital chip which
does the decoding of the resolver sin/cos signals.
SSI Interface : SSI is a high speed serial interface used by modern digital position encoders.
DC Voltage Interface: The third position encoder interface module contains an A/D
converter which is suited to measure the DC voltages produced by simple inductive angle
encoders. This application is for small antennas especially in the SNG business.
The paragraphs below give a short overview to the contents of the documentation. A subset of
this documentation is stored on the device itself, the complete documentation is available on the
sat-nms documentation CD and at www.satnms.com .
