sat-nms MNC Monitoring & Control System

SatService´s Monitoring & Control System sat-nms MNC is a comprehensive software-based system providing monitoring and control of any type of satellite ground station and associated baseband equipment.

The system consists of two parts:

  • 2RU 19" Industrial PC with Ethernet interface and serial interfaces connected to the ground station equipment
  • sat-nms IO-FEP parallel interface for low level devices like alarm contacts or waveguide/coxial switches.

The sat-nms MNC Software is seperated into two in Java implemented modules: sat-nms MNC Server and Client. Both modules are installed on the industrial PC and running under the Linux operating system. The platform-indepented client software can also run on every TCP/IP connected workstation.


  • Client Server Software Architecture
  • TCP/IP-based Design
  • Server operating under LINUX with full remote Administration and Support Capability
  • Clients are operating independent from System 
  • Unlimited Number of Clients possible
  • Event/Alarm Log with a lot of Filter Utilities
  • Task- and device-oriented User Interfaces
  • Macro Recording Functionality
  • Software configurable Interface Device Configuration
  • Integrated graphical Tool for User Interface Configuration
  • Comparable Equipment of different Manufacturers has the same "look and feel"


  • VSAT-Hub
  • SNG, SNG Central Station
  • TV-Uplink
  • Teleport


  • 2RU 19" rack-mount Industrial PC
  • LAN (TCP/IP) Interface
  • Power Supply Wide Range Input Voltage 90V to 240V 50/60Hz AC
  • CD- and ZIP-Drive for Backup Capability
  • Rack-mountable 15" TFT Monitor, Keyboard and Trackball for local Control

Interfaces to Satcom Equipment

The sat-nms MNC is able to monitor and control the attached equipment via the following types of interfaces:

  • Serial RS232 Interface
  • Serial RS422/RS485 Interface
  • Network Interface (Ethernet,TCP/IP)
  • SNMP Interface via Network
  • Parallel Interface for low level Devices like Alarm Contacts or waveguide/coaxial Switches via the sat-nms IO-FEP

sat-nms MNC-Server

The sat-nms MNC Server monitors and controls the equipment of a satellite ground station. The monitoring is performed locally without any influence and connection by any operator client. The connected equipment is polled and monitored continuously. Typical alarm flags of the equipment, like summary alarm, lock alarm, etc., thresholds or limits of data quality are detected. The alarm message is stored in the internal sat-nms MNC database at the sat-nms MNC Server and the client operator is alerted via both a graphical and an audible alarm.

Virtual Device Driver defines families of satellite ground station equipment with common user interfaces for operator with multi vendor equipment in the field, e.g. all satellite modems are presented to the operator in the same look and feel. This simplifies the handling because device specific details are hidden from the operator.

Logical Devices are also available like EIRP Adjustment, Data Logging (any parameter that is displayed can be logged to file), Redundancy Switching and Site Diversity Switching.

sat-nms Drivers

The Universal Device Driver concept reduces the cost for the configuration of new drivers. The user can configure its own drivers without writing software. Parallel to that SatService will always provide the service to adapt new equipment with drivers to the system. Drivers are always the same for sat-nms MNC- and VLC-Systems.

The Driver Development Kit (sat-nms DDK), which is an eclipse-platform-based Integrated Development Environment supports the user to configure and test new drivers and protocols. For details please see datasheet.

Device Licenses, Configuration Changes and Upgrades

The basic sat-nms MNC-0/0 System already contains 5 device licenses that can be used, e.g. for devices connected via TCP/IP. Additionally, each sat-nms MNC System Package contains device licenses for every serial interface that is included e.g. the sat-nms MNC-4/8 System contains 5+4+8=17 licenses to monitor and control 17 units.

With the included configuration tools for the interface setup and the graphical user interface our customer is able to add, remove or change the connected equipment. Our customer is also able to add new types of devices from the sat-nms Driver Library or even configure new drivers by himself.

This flexible approach provides you with all possibilities to use our sat-nms MNC System even with changed conditions in the future. Upgrade kits to extend the number of available interfaces are also available.

sat-nms MNC-Client

The client software is the user interface for the operator of the ground station. The operator accesses the sat-nms MNC System directly via the sat-nms MNC Industrial PC or via an arbitrary workstation in the network connected via TCP/IP. The number of clients is not limited.

The platform independend Java software requires only a Java virtual machine on the Client-PC. We have tested the software successfully on Windows 9x/NT4/W2K/XP/7/8 and of course on Linux PCs.

With the purchase of the sat-nms MNC System you obtain the licenses for an unlimited number of clients so that you do not have additional costs.

There are two kinds of user interfaces available:

The device-oriented user interface provides all parameters of the satellite ground station equipment and gives a deep insight in the equipment for system engineers. It is part of the delivery and shows every attached device in a block diagram view. The device-oriented screen will be mostly used in stations with a static configuration for monitoring & control and redundancy switching.

The task-oriented user interface is a customized user interface, fully configurable and reduces the user interface to the special requirements of the operators. Several task-oriented and or device-oriented user interfaces can be used in parallel. SatService will be glad to offer you the configuration regarding your needs, but you are also able to do this on your own with the integrated graphical screen editor.

Remote Access

The sat-nms MNC Server is completely configurable and maintainable remotely. These actions only require a TCP/IP connection and for the clients only a TCP/IP connection to the sat-nms MNC Server. This can be an already existing network (LAN) or a dialup connection (e.g. PPP).

SatService offers also ISDN and VPN solutions to connect different locations on request. Via these routers SatService can give you remote support if you need it.
