Fraunhofer IIS's research unit on positioning and navigation has expertise in the following technologies:

  • AoA – Angle of Arrival:

    The angle-of-arrival (AOA) method measures angles in real time and is suitable for both indoor and outdoor use. A robust infrastructure makes it possible to perform hundreds of measurements per second.

  • ToF - Time of Flight:

    Time-of-flight (TOF) methods can provide positioning accuracy of less than a meter. If UWB technology is used, transmission through obstacles such as walls is possible.

  • CoO - Cell of Origin:

    The cell-of-origin (COO) technique is a basic mobile positioning technique that considers the unique identifiers of base stations and in some cases their locations. More sophisticated versions of this technique analyze information from a large number of cells.

  • RSSI - Received Signal Strength Indication:

    If there are communication networks available, for instance in the form of WLAN, GSM and UMTS base stations in indoor or urban outdoor environments, then mobile devices can independently determine their positions based on the strengths of signals received. This is known as "received signal strength indication" (RSSI).

  • INS - Inertial Navigation System:

    Inertial navigation involves the use of self-contained measurement units that determine the distance traveled by an object as well as its current orientation based on a combination of accelerometry and rotation sensing.

  • LST – localization software toolkit

    Our Localization Software Toolkit encompasses modules for positioning with the following satellite navigation systems: GPS, GLONASS, Galileo and EGNOS. We also offer variants according to your accuracy specifications and application environments. The localization software toolkit contains all modules required for complete receiver solutions (sensor fusion, embedded operating systems, system software).

  • Cooperative Networks:

    If distributed objects form a wireless network, the relationships created by data exchange among them make it possible to determine the objects' relative positions within the network.

  • GNSS - Global Navigation Satellite System:

    This satellite-based navigation system does not require any additional infrastructure. It is used, for example, in surveying to determine locations with an accuracy of a few centimeters.

    • More Information…

  • Event Detection:

    Many applications are designed to provide not positioning data as such but a reliable basis for decisions, controls and insights.

  • Sensor Fusion and Cooperation:

    Since requirements can be manifold, depending on the intended use, a single technology is often insufficient.

  • Environment Modeling:

    Many applications require information not only about the position of an object but also about its surroundings.
