sat-nms Antenna Control and Tracking System

The sat-nms ACU product family can cover antenna control which reaches from positioner only applications up to a full featured adaptive step-track system. In order to cover these user requirements the system is divided into two modules:

• sat-nms ACU-ODM (Outdoor Module)
• sat-nms ACU-IDU (Indoor Unit)

Applications

• Antenna positioning
• Antenna Step Track
• The sat-nms ACU can operate as stand alone solution or fits into the overall sat-nms Network Management System solution provided by SatService

ACU Outdoor Module

The sat-nmsACU-ODM module is a three axis antenna positioner (with optional step-track capability) which provides all interfaces to the three motor controllers. To measure the azimuth, elevation and polarization angle three different interface types are available.

The module can be directly integrated in a cabinet at the antenna and together with the sat-nms LBRX Beacon Receiver it is possible to have a complete step track system integrated in the antenna cabinet.

The sat-nms ACU-ODM module includes a web server and provides its operator interface via web browser. The system is easy to maintain and all support can be controlled remotely. Also the interface to high-level M&C systems is provided via Ethernet and TCP/IP.

The modular architecture and standard interfaces simplify new or retrofit integration. The sat-nms Antenna Control System is an economic alternative to the systems provided by antenna manufacturers. SatService GmbH provides upgrade kits for all antenna types on the market and can also perform on-site system integration

Key Features Outdoor Module ACU-ODM

• Ethernet interface
• Web based user friendly operator interface
• Optional Step Track algorithm and Adaptive Tracking with self-learning orbit model tracking algorithm
• With sat-nms LBRX a complete step track system in cabinet at the antenna
• HTTP protocol for external M&C interface
• Interoperable with Andrew, Vertex and NEC antennas and systems

ACU Indoor Unit

The sat-nms ACU-IDU is for customers who want to have a more classical antenna step track system which also has an indoor unit. This ACU system does provide even more functionality, like data archiving, adaptive tracking, tracking on the basis of Intelsat data, two line Kepler elements, graphical presentation of the angular and beacon level variation via time and other sophisticated features.

The sat-nms ACU-IDU is an industrial PC incorporating digital technology for accurate antenna tracking with high reliability, flexibility, and a user friendly operator interface. This system is ideally suited for all kind of satellite ground station antennas.

The SatService Adaptive Tracking algorithm performs the function of conventional step track peak signal level optimization but without the random "guessing" errors associated with predetermined fixed scan patterns.

Key Features Indoor Unit ACU-IDU

• Ethernet between indoor and outdoor
• User friendly interface
• Real-time position readout and fault message reporting
• remote maintenance and support
