Hardware architecture

The GalTeC architecture basically consists of a scalable server/client architecture with several computer systems on which the different software-based functions is realized.

The basic hardware is mounted in a single 19" rack that consists of the three GalTeC servers with integrated mass storage. The various analysis and evaluation software on the GalTeC servers require access to the Internet in order to download actual data from the various sources delivering GNSS measurements and evaluated data. The external access to GalTeC servers is also provided through the Internet.

The GalTeC servers are connected internally to local users through their own work stations where individual computations can be performed. There is also one operator workstation (GalTeC Client) directly connected to the servers and located in the laboratry.

The figure shows the contents of the GalTeC System Rack, which contains the integrated GNSS receiver at the top, a network interface, the simulation server, the server for the reference orbit determination and user reference PVT computation, the server for the analysis function and the provision of services to the users. This is complemented by an uninterruptible power supply (UPS) to ensure continuous operation.

The following figure shows the primary Client-1 at in the Thales ATM laboratory.
