  • 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.



    APPLICATION PROGRAMS :
    Observation Space programs - CSO (2013) - HREOS (2017)



  • Test of Radars Altimeter Embarked on Satellites

  • Radar Echo Simulator

     

    Acquisition of RF radar signals (C-band or Ku band) - Conversion to digital signal and processing to simulate the affected target and propagation of an earth / Satellite route - Reconversion to analog signal for radar processing.

    Performances :


    • Analogic—digital conversions,

    • Altimeter interfacing,

    • Signal processing (FFT, FIR, complex multiplication…).

    APPLICATION PROGRAMS :

  • Special Check Out Equipment - SCOE

  • Functional Testing, Integration and Validation Test Benches

     

    NEXEYA designs complete HMI-driven systems (SCOE), integrating not only the systems described above but also more specific systems of acquisition, simulation or generation with provision of power supply, harnesses …

     

    • Subset developed specifically by NEXEYA or off-the-shelf products,

    • Rapid development raised by NEXEYA basic technology building bricks,

    • Equipment power supply protection and signal insulation,

    • Integration of several space serial buses, analog telemetry, high power commands,

    • Simulation of plasmic propulsion,

    • High level user test controller interface allowing synoptic development, database management, real time and post-processing.




  • 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.
