A Flexible Embedded Hardware Platform Evaluates Multimodal Localization And Motion Monitoring Algorithms

   What Is HYLOC?

HYLOC is a flexible embedded hardware platform designed to evaluate the latest hybrid data fusion algorithms for precise, resilient multimodal localization and motion tracking. Built around a high-end digital signa lprocessing module and an FPGA, it integrates:
  • GNSS receivers using standard and high-accuracy GPS RTK technology
  • An ultra-wide band radio
  • ISM-compatible, 868 MHz and 2.4 GHz communication band radios
  • A consumer grade, low-cost measurement unit
  • A tactical grade, high-accuracy inertial measurement unit

  Applications :

Hybrid data fusion algorithms for multimodal localization are often difficult to optimize for environmental and operating conditions. Leti HYLOC accelerates optimization from algorithm development to implementation to:

Explore unknown environments or challenging contexts, in which localization is critical, such as:

  • Autonomous vehicle technology
  • Industry of the future
  • Personal asset management
  • IoT data geo-referencing for Big Data analysis
  • Next Human-Machine Interfaces & Virtual/Augmented Reality

Evaluate alternative fusion modalities based on flexible mother/daughter board architecture


  What’s new?

  • Localization scenarios can be recorded in log files for consumer metrics and high-end components. Fusion algorithms can then be fine-tuned offline
  • Communication protocol impact on and from localization fusion algorithms can be assessed
  • Fusion algorithms can be embedded in real-time CPU for early prototyping
  • HYLOC can be used as a baseline for more integrated RTLS or stand-alone solutions
  • Simultaneous GNSS (GPS and GPS RTK), radio (ISN and UWB) and inertial (tactical and consumer IMU) access to consumer and high-end localization sensors can provide exhaustive benchmarks
  • Small form factor of complete solution foreshadows future systems and facilitates field trials
  • Flexibility in adding new localization or communication modalities and technology contexts, while managing gradually increasing system complexity

 What’s Next?

HYLOC updates can be considered to support new technologies such as:
  • Emerging radio accesses: 5G, IEEE 802.11p, LPWA
  • New GNSS solutions, e.g. Galileo
  • Alternative high-end or consumer IMU components
