Spirent Federal Systems' Participation In Galileo

Spirent has been selected by Alcatel Alenia Space and Thales, the organizations overseeing the Ground Mission Segment (GMS) and Test User Segment (TUS) elements, of the project respectively. Spirent's RF Constellation Simulators will generate radio frequency signals that are representative of the real signals to be transmitted from Galileo satellites when the project is fully deployed.

The main purpose of Spirent's solution will be to test the performance of the receivers used in the GMS and user receivers which form critical elements of Galileo system development. The GMS stations control the satellite constellation and the TUS forms the basis for future Galileo user receivers that will be used in a wide variety of application areas on sea, air and land. Spirent's simulation systems will enable the Galileo project to fully test critical receiver technology in advance of full system availability.

Other key features of the RFCS include:
  • Enabling full performance verification of the GMS and TUS receivers
  • Testing in adversarial and error conditions to improve the resilience of the Galileo receivers
The systems provided under this contract have recently been upgraded with new software capabilities and signal generator hardware. Over the next couple of months comprehensive verification testing will be completed in Spirent's newly completed facility, pictured below.

The Spirent verification facility consists of reference versions of our Galileo system as well as reference systems for all of our existing product range. The Galileo rack will be used for full verification testing of our reference Galileo system as provided to the Galileo program.

For the rest of our existing product range the facility is being used as an integral part of our support infrastructure to enable Spirent to provide technical support even more effectively.
