sat-nms ACU2-19V2 User Manual

Abstract

The sat-nms ACU19V2 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

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

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 .

Safety Instructions : This chapter gives an overview about the safety precautions that have

to be observed during installation, operation and maintenance.

Unit Overview : The installation chapter gives informations about the different modules that

are integrated in the ACU (not ACU-ODM and ACU19).

Installation/Start-up : The installation chapter guides through the installation and setup of the

ACU outdoor module. It describes the mechanical concept of the ACU and the assignment of

the ACU's connectors. It gives you informations about the starting up procedure. Finally you

learn in this chapter how to set the ACU's IP address, which is a essential precondition to

operate the ACU by means of a web browser.

Operation : The sat-nms ACU is operated using a standard web browser like the Internet-

Explorer on MS Windows based computers. The user interface design is straight forward and

clearly structured. Operating the ACU is mostly self-explanatory. Nevertheless, the

'Operation' chapter outlines the map of web pages which make up the ACU user interface

and elaborately describe the meaning of each alterable parameter.

Frontpanel Operation : The sat-nms ACU19 and the sat-nms ACU-RMU optionally are

equipped with a frontpanel Human-Machine-Interface. This chapter describes how to use this

interface.

Remote Control : The ACU outdoor module provides a versatile remote control interface. A

monitoring & control software may fully operate the ACU either through a TCP/IP network

connection or through the RS232 interface of the ACU. This chapter describes the

communication protocol used for remote control and lists all parameters accessible through

the remote interface.

Theory of Operation : This chapter gives a short overview how the ACU works. It also

describes the different tracking algorithms and their parameters. The interaction with a

beacon receiver is described as well. Knowing about the theory regarding this functions

helps to find the best parameter settings for a given application.
