Secure Communication Networks


For the Galileo Ground Mission and Control Segment Network, Antwerp Space was responsible for delivering both hardware and software design, integration and maintenance towards its prime contractors, Thales Alenia Space and Airbus.

This implies requirement engineering, shaping the network design, defining the roadmap and product definition at network node level as part of the design phase.

Antwerp Space was also responsible for product assembly, rack integration and functional integration of the network nodes. 

The project version-controlled repository consisted of more than 27000 items, mainly configuration files for bespoke software, routers, security COTS appliances and software, servers and workstations. To ensure the scalability (multiple instances of each node type resulting in about 140 nodes) templates based on a typical configuration were used to create the different configurations. An automatic build process was engineered in order to ensure the creation of all specific configuration files which resulted in a new release.


A representative reference platform was setup in our premises, allowing integration and qualification of the different rack nodes (12 types/multiple instances per type) and security zones to mitigate the risk on the final deployment. 

In this network a typical configuration of all the different nodes types is foreseen, and interconnected via a GDDN simulation in order to do representative tests.

This reference platform allows management and control of both MDDN and SDDN elements. The different Galileo traffic flows can be created (if needed with the aid of traffic generator tools).  Both inter-GCC traffic as well as traffic to-and-from the remote nodes and external entities. The dual lane/dual GCC-site platform allows for redundancy and handover testing.

Software deliveries were built and packaged in-house, followed by a factory acceptance test campaign.  In a number of cases, the releases were deployed by our engineers “in-the-field” followed by a formal site acceptance campaign. In other cases we prepared and dry-ran in-factory roll-out procedures for mission critical and in-operations systems.

After successful qualification large volumes of network nodes were deployed world-wide.

The team was responsible for delivering training material and for training the customer, operators and the maintenance team, both on-site and in our premises.

Aside from maintenance support Antwerp Space has demonstrated its capability to support GALILEO into its FOC1 phase by delivering a major obsolescence resolution release swapping out three major security COTS.

Given our experience in Galileo IOV and FOC1 Antwerp Space understands what it means to deliver and guarantee the long term availability of its integrated network solutions for these kinds of important programs.
