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.
