As a major player in the space industry, NEXEYA provides developers/integrators of satellites and space launchers with state-of-the-art test systems and EGSE to carry out their critical space programs.


These means are based on our ever developing expertise and know-how in critical electronics throughout numerous client projects.


Our solutions are based on standard and proven hardware and software, combining high level of performances and reliability with costs and deadlines imposed by market.


In addition to the solutions presented hereafter, we built tailor-made solutions and we are at your side all along the life cycle of your products: from first definition up to operational phases.

  • Acquisition/generation of High Speed Numerical Links for functional validation requirements

  • Acquisition front-end and satellite image processing on LNR3 (3rd generation rapid digital link)


    The system is based on generic acquisition and high-speed generation cards (> 5GHz), and configurable modules for signal processing and adaptation.


      • Digital links VML technology series, CML and PECL compliant,

      • Design with the latest generation of FPGA programmable components (VIRTEX 6) to meet customer needs faster,

      • Manage multiple links simultaneously (up to 6) in real time ,

      • Pixel re-arrangement, statistical processing,...,

      • Possible to share acquisitions via Ethernet.

  • Launcher Telemetry Reception, Decommutation and Processing

  • MAGALI Stations & Control Room


    With 30 years of experience in Telemetry, NEXEYA has developed high performance solutions, from the single system to the complete telemetry facility, for launcher operations follow up: final assembly, countdown, in-flight monitoring and post-flight analysis. MAGALI stations receive, acquire, simulate and analyze one to several PCM data streams (CCSDS) and can distributes data to numerous stations for visualization and processing. MAGALI solutions offer many benefits:


    • Open system, both configurable and upgradable,
    • Quick implementation,
    • Autonomous for totally secure data recording and archiving,
    • Redundant system,
    • Rapid integration of new tests,
    • Network architecture for configuration requirements and distribution.
