SkyRack ATC - System Monitoring and Control - Description


SkyRack is ATM-grade server cabinet. On the front side it includes a trouble shooting panel, measurement sockets, servers and 2 UPS. The read side offers a multitude of options for the trainer to degrade the system. It is an infrastructure for monitoring and control exercises with SkySMC, the pedagogical, but fully operating monitoring and control solution. It can run together with the NextGen 8 GHz Radar, our fully operational ATM system, the virtual infrastructure or to any external system with standardized Object Identifier Codes (by ITU or/and ISO).

SkyRack ATC provides the important use cases for ATSEP qualification in line with EASA's Easy Access Rules for ATM-ANS (Regulation (EU) 2017/373) ATSEP.BAP.SMC.

This infrastructure solution comes as hardware. Depending on the destination it will be shipped disassembled and assembled at customer site, or it will be shipped readily installed right away. The servers include pre-installed software (depending on the destination, the software will be installed in the destination country).

Server Cabinet with Rack

The cabinet can be accessed from 2 sides.

The front side is what is visible to the trainee. It is a typical ATC server arrangement. Trainees need to make use of the system control and monitoring software SkySMC to detect errors or system degradations before applying the right recovery strategy.

The rear side shows the manual hardware-based control panel. The teacher can manually enforce system degradations or errors.  He or she can e.g., switch off certain network connections, or hardware components by interrupting the power supply.

19" Rackmount Touchscreen and Socket Rack

SkyRack includes a 19" touch-panel, accessible from the front side. This touch-panel can show varying troubleshooting screens.

19" Rack-Mount The Socket-Rack

The socket rack allows to do physical measurements on the system with oscilloscopes and multimeter. Various configurations of socket racks are possible (suitable for SUR, COM, NAV).

2 Server Modules

The server rack is equipped by default with 2 server modules. The modules contain databases and applications like the small pedagogical FDPS. The various applications communicate with eachother through the physical network. The applications provide typical ATC constellations in a nutshell.

Software Applications & Databases

The software applications include e.g.,

  • NGINX - a commonly used is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. The ATC environment includes a sample websites, its IP is 172.17.02.
    We can for instance refresh the website. Consequently the requests per second in the Nginx server will increase
  • SNMP server - SNMP is widely used in network management for network monitoring. SNMP exposes management data in the form of variables on the managed systems organized in a management information base (MIB) which describe the system status and configuration. These variables can then be remotely queried (and, in some circumstances, manipulated) by managing applications. In the example it is a pure SNMP server. IP 172.17.03
  • Pedagogical Flight Data Processing System (server) - it is a web service on IP 172.17.04. This pedagogical FDPS provides simulated data on arriving and departing flights. The events happen faster than in reality in order to see changes faster. 
  • Distributed Control System (DCS) für fire monitoring. The server includes an DCS system for fire monitoring in gas or kerosine. The system can be connected to real Airport Rescue and Firefighting installations for training purposes or real ARFF training aircraft. Relevant monitoring data is passed to SkySMC.

Network Routerboard

The network routerboard consists of of a4-Port Ethernet Line Breaker with relay controlled Ethernet ports and integrated I/O module.  It is a is a cybersecurity system for industrial networks that can physically disconnect Ethernet connections. It features relay-controlled 10 Gigabit Ethernet ports, each of which can be turned on and off via a toggle switch on the device as well as remotely. Remote control is based on standardized communication protocols.
The teacher can cause network errors and degradation manually though physical switching or remotely through the teacher panel in the SkySMC.

Power Strip

The switchable power strip allows to manually switch on and off Servers and Facilities.
The teacher can cause network errors and degradation manually though physical switching or remotely through the teacher panel in the SkySMC.

2 UPSs

The system is equipped with 2 Uninterrupted Power Supplies (min 3x750 W). Through SNMP, The SkySMC System Monitoring and Control software can monitor the USPs. 

From teacher panel, the teacher can switch on and off the USPs.

Fan with Thermostat

The system includes a Fan with Thermostat.

Fire Detector (Optional)

An important Facility in the ATC landscape is fire detection and monitoring. 

The server cabinet can be extended by a fire detector with SNMP communication to be monitored by SkySMC.


Expandable System

The monitoring environment is able to include a variety of different labs, including the NextGen radars, the ATC Radar and Tower Simulator, or various electronical and electro-mechanical labs.
